West Africa Water Expo: 7th International Water & Waste Water Exhibition, which is organized by Elan Expo, will be held on 20-22 May 2025 at Landmark Center in Lagos, Nigeria. Improved water sources Nigeria is one of the biggest countries in Africa with its increasing population and annual GDP rates. With the increase in the population, the urbanization process is speeding and the local people have low-level access to improved water sources and sanitation. Wastewater Management in Lagos State as the case in other parts of Nigeria is minimal, with only a fraction of wastewater being treated. Sanitation systems currently used in Lagos State include both government and private facilities. The government cannot afford to fill the gap that exists between the current capacity of the state water corporations and the required daily volume for the state’s use. According to the government, the private sector is thus encouraged to invest in the sector. Wastewater treatment facilities The General Manager of ELAN EXPO, Mr. Suer Ay illustrates his opinions about the Nigerian Water industry as; "Nigeria is not a water-poor country, it needs more investments. Nigeria produces 1800 m3 of water per capita annually; there are enough water resources for domestic, industrial, agricultural, hydropower, transportation, and recreational uses but there is more need for modern wastewater treatment facilities during the rapid urbanization process." Mr. Suer Ay adds, "In this year's Wawe Expo 2024, we served the local people to meet international suppliers for Water And Waste Water Treatment, Transport & Storage, Process Control & Automation, Engineering, And Flood Control/Storm Water." Global brands and companies  West Africa Water Expo 2024 attracted 172 global brands, representing companies from 25 countries West Africa Water Expo 2024 attracted 172 global brands, representing companies from 25 countries, as well as more than 8600 visitors throughout the World: Bulgaria, Canada, China, Egypt, Germany, Ghana, India, Italy, Japan, Lebanon, Morocco, Nigeria, Poland, Russia, S.

Swedish heat pump manufacturer Qvantum has officially introduced its UK business, with invited guests attending the launch event at its new headquarters in Moorgate, London. Priding itself on being ‘more than just a heat pump manufacturer’, Qvantum’s ambition is to heat the cities of Europe using affordable renewable technology, alongside a commitment to generating positive change in electricity grid balancing. Unique heat pump solutions Qvantum UK CEO Phil Ord said: “We believe our unique heat pump solutions genuinely bring something new to the UK and can provide the impetus to redirect the way we consume energy to service the needs of the domestic heating and hot water market." “A big part of the challenge is to harvest and store renewable energy when it is plentiful, often in excess of what we actually need, and use it when demand increases above the generating capacity of the grid. Qvantum is here to help shift that peak.’’ Innovative line-up of solutions The innovative line-up of solutions includes: QE: exhaust air heat pumps (4kW/6kW) capable of providing heating, instantaneous domestic hot water and ventilation. As an added benefit, the QE is also able to provide a degree of cooling with a flow temperature of circa 18°C. This is not comfort cooling that can maintain a set room temperature but ‘overheat mitigation’ aiming to prevent adversely high temperatures and assist compliance with Part O. QG: a water-to-water, geothermal or ambient loop apartment heat pump system (6 kW/12 kW) supplying heating, cooling, and instantaneous domestic hot water for both single households with individual collectors as well as in ambient or low-temperature water loop applications. QA+QH-XL/QH-L: compact pre-plumbed hydro units used in conjunction with a Qvantum R290 (propane) monobloc air source unit (9 kW/15 kW). Qvantum heat pumps Thermal batteries have a capacity of up to 12 kWh and enable all Qvantum heat pumps to shift energy Qvantum’s business model has seen it invest heavily in technical and aftersales support personnel before product development, ensuring that the pain points of the heat pump and energy sectors have been identified before deciding how to address them and with what products. A modular design concept means that 80% of components are shared across the product line, including the unique integrated QH water tank shared across all three ranges, which is used as a thermal store and charged like a battery. The thermal batteries have a capacity of up to 12 kWh and enable all Qvantum heat pumps to shift energy consumption for heating and hot water away from peak periods, easing the load on electricity grids and reducing environmental impact through the time of use (ToU) shifting, in addition to considerable running cost saving for the property owner. Integrated thermal store The thermal store can be heated to high temperatures by the heat pump or an integrated immersion heater, consuming electricity when it is cheaper, in abundance, or produced during low carbon intensity.  Hot water is produced indirectly via a plate heat exchanger using energy from the thermal store, so the need for a legionella pasteurization cycle is removed. A property’s heating system can be served directly from the heat pump compressor module at any time or from the thermal store for peak load saving, or a mixture of both. cloud-based control solutions FLEXREADY®, an open API that enables 3rd-party cloud-based control keys to integrate with product line-up FLEXREADY® is an open API that enables third-party cloud-based control solutions to integrate with Qvantum’s product line-up. It is currently used to interrogate and monitor systems remotely connected via Wi-Fi, but when used more widely it will enable energy providers to charge hundreds of thousands of thermal stores on demand when the production of electricity outweighs its consumption. This will reduce the amount of time renewable energy generation is dormant because of grid capacity and lessen the reliance on fossil fuels to generate electricity during peak periods, simultaneously reducing the home’s running costs and carbon emissions. Qvantum’s products Qvantum’s products are backed by manufacturer-supported national service coverage from over 130 engineers. The products are installed and commissioned using dedicated apps that provide step-by-step guidance, data logging, installation and user manual access, and system registration.  A service app is accessible for system monitoring with actual operating data displayed alongside system schematics for easy understanding. Qvantum’s modular product concept Training is fed in-house with an online platform and face-to-face at Qvantum’s dedicated training room The Q-support remote monitoring service offers live data viewing and logs historical data, so service engineers can review it before attending the site, reducing first-fix repair times. Qvantum’s modular product concept also means that engineers can carry a reduced number of parts, knowing that 80% are interchangeable throughout the range. In addition, engineers who do not hold refrigerant-related qualifications can remove compressor modules by disconnecting hydronic connections only. Training is provided in-house with an online platform as well as face-to-face at Qvantum’s dedicated training room at its Moorgate offices. Training facilities and product line-up Guests at the launch were able to explore the training facilities and product line-up, following presentations from Phil Ord and Qvantum UK colleagues Darren Manley (Technical Sales Director) and Geoff Turton (Aftersales Technical Director).  Further background was provided by Thomas Nowak, former Secretary General of the European Heat Pump Association, who is now Qvantum’s VP of Government Relations and Public Affairs.

Data centers worldwide are under intense pressure. High-powered computing is a global necessity that seemingly gets more demanding by the day. There’s also the need to prioritize sustainability improvements ranging from resource conservation to decarbonization. And data centers must consider their bottom line and remain competitive. Anticipating the challenges data centers will continue to face, scientists and engineers have innovated two-phase (2-PIC) immersion cooling. With the capacity to meet the elevated cooling requirements driven by high-powered computing, this next-generation solution delivers on environmental priorities by significantly lowering data center energy consumption, slashing, if not eliminating, water use, while supporting decarbonization, circularity missions, and more. Emergence of 2-PIC Traditional approaches are fast approaching capacity for meeting current and future cooling needs The emergence of 2-PIC comes at a critical time, because the traditional cooling methods that have kept data centers up and running so far—namely air cooling and water cooling—are doing so at the detriment of the planet.  Additionally, these traditional approaches are quickly approaching capacity for meeting current and future cooling needs. Air- and water-cooling methods are used in approximately 95% of the estimated 8,000 data centers that exist today. The criticality of high-powered computing Once seen as a future need, high-powered computing, and faster-than-ever processing are now established as critical to the operation of businesses, governments, organizations, and other entities that support the way communities function, survive, and thrive. Whether it’s health and wellness, financial institutions, economic growth, safety and protection, entertainment, education, or any other service supporting our way of life, successfully providing that service fully depends on the ability of data centers to quickly and reliably obtain, store, and process data.  Influence of AI AI has a profound influence and, generates far more power than traditional internet uses Moreover, when we say “data centers,” we’re not just speaking of big players like Microsoft, Google, Meta, and Amazon. Equally dependent on high-performance, high-speed computing are enterprise data center operators, such as our governments and military, financial institutions, healthcare systems, educational institutions, and more.  We also must acknowledge the profound influence of artificial intelligence (AI), which generates far more power than traditional internet uses. Its effects are far-reaching, enhancing patient care, supporting risk management and fraud detection in finance, boosting crop yields within agriculture, and more. The environmental costs of data centers According to the latest estimates by the International Energy Agency, data centers worldwide produce 1% of energy-related carbon emissions and in 2022 used approximately 460 TWh of electricity per year—equating to 2% of global electricity demand. McKinsey and Company estimates 40% of this electricity is used for data center cooling. Data centers’ impact on the environment also includes their significant water consumption, averaging 300,000 gallons per day, and a physical footprint that averages 100,000 square feet but in the case of some hyperscale data centers can range between 1.3 to 2 million square feet. In terms of growth, a U.S. market report from Newmark tells us that in the U.S. alone, the U.S. data center footprint will absorb 35 gigawatts by 2030, which is more than twice the data center power consumption of 2022. The emergence of liquid cooling: the elevated interest in 2-PIC From reducing energy and water consumption to shrinking physical footprints, 2-PIC offers the planet a better data center solution. In less than two years, traditional cooling systems won’t be able to support the exponential growth in the world’s data processing and storage applications. Based on publicly available product roadmaps from major chip manufacturers, by 2026, air-cooled systems will no longer be able to meet the cooling needs of most next-generation, high-performance computing chips. Capable of removing heat more effectively than air cooling, liquid cooling uses a liquid such as water or a dielectric fluid to cool the heat-generating components of servers. The liquid can cool these components directly, or it can be done indirectly through a heat exchanger. With two-phase immersion cooling the entire server rack is submerged in a tank filled with a dielectric fluid. Single-phase and two-phase liquid cooling Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system. Two-phase liquid cooling uses a phase-change material, such as a refrigerant, which evaporates and condenses as it absorbs and releases heat. With 2-PIC, which is a form of two-phase liquid cooling, the entire server rack is submerged in a tank filled with dielectric fluid. The fluid boils as it’s heated by the components of the servers, creating bubbles that rise to the surface and condense in a heat exchanger. Gravity then returns the condensed fluid to the tank, creating a natural circulation loop that does not require pumps or fans. Advantages of 2-PIC 2-PIC is commanding attention as the solution for meeting the cooling demands of the high-powered computing components of today and tomorrow. Moreover, the technology of 2-PIC systems, combined with the right dielectric fluid, delivers advantages to “take the heat off” data centers. Here’s a breakdown of additional 2-PIC benefits: Up to 90% reduction in energy consumption: Based on modeling completed by the industry, 2-PIC is expected to reduce up to 90% of data center cooling energy consumption and 40% of overall data center energy consumption*. (*Compared to traditional air-cooling technologies) Enhanced computing performance and data center reliability: 2-PIC allows servers to operate at higher temperatures and power densities, while reducing the risk of overheating. Significant reduction in water consumption: Depending on the data center location and cooling design methodology, water consumption could even be eliminated completely. 60% reduction in the physical footprint: 2-PIC reduces the space required for cooling equipment, freeing up more floor area for servers and increasing the rack density of the data center. Lower GWP and circularity: Chemours Opteon™ 2P50 is a developmental dielectric heat-transfer fluid, currently pre-commercial, pending regulatory approval. It offers an extremely low global warming potential (GWP) of 10 and was specifically created to optimize the performance of the electronic components in a 2-PIC system. This 2-PIC fluid also enables the reprocessing/reuse of existing fluid to maximize circularity.  The bottom line: In addition to other compelling data, a recent study commissioned by Chemours and LiquidStack through Syska Hennessy, revealed that, compared with other state-of-the-art liquid cooling methods, 2-PIC can deliver up to a 40% lower total cost of ownership (TCO) and significantly reduce operational expenditures (OPEX), with savings ranging from 54% to 88.6%. Benefits of new data center cooling technologies compared to single-phase direct-to-chip, and single-phase immersion methods. 2-PIC, the future-ready solution As the world’s reliance on AI and other high-powered computing capabilities escalates, data center cooling solutions must grow with demand while significantly reducing their impact on the environment. In global energy savings alone, 2-PIC could generate an estimated savings of 340 TWh by 2055—the equivalent of powering more than 517 million laptops 24/7. And even with increasing IT loads, 2-PIC maintains its performance, ensuring long-term cost-effectiveness and adaptability to meet future demands. With society at a crossroads between the criticality of high-powered computing and a planet in crisis, the industry is turning its attention to 2-PIC as the solution for today and tomorrow.

Until a couple of years ago, most of the talk about heat pumps occurred around this time of year, when more than half the planet prepares for an autumn cooldown. These discussions were typically limited to regions that only experienced moderate winters. But as anyone who has recently perused an HVACR trade magazine or website—or participated in an industry webinar, event, or social media conversation—can tell you, the topic of heat pumps is virtually unavoidable. Not only do heat pump discussions now occur year-round, but they’ve also ascended to consistent headline status and transcended the traditional boundaries of moderate climates.  The decarbonization megatrend One might say heat pumps have taken their place on the global stage. If you’re asking why this has happened, the answer requires just three words: the decarbonization megatrend. However, for industry professionals looking to grow their businesses, it’s helpful to gain a deeper understanding of heat pumps—how they work, ways they are currently meeting HVACR needs, and where the technology is headed for next-generation applications. Through this understanding, members of the industry can better forecast customer needs as well as identify opportunities for expanding in both current markets and, potentially, new ones. How heat pumps work—don’t let the name fool you The heat released as the refrigerant condenses is then transferred to interior spaces What heat pumps do and, more specifically, how they do it provides the key as to why they are now being considered a “hero” of decarbonization. The term can be misleading, because “heat pumps” do not generate heat. Because of this, heat pumps are being more widely embraced as the lower-carbon-emission alternative to combustion-based heating technology that uses, for example, fossil fuels.  Instead of creating heat, heat pumps extract heat energy from where it’s not needed and move it to where it is needed. When a heat pump is in heating mode, its refrigerant evaporates as it absorbs heat from the outside. The heat released as the refrigerant condenses is then transferred to interior spaces. In warmer weather, a heat pump kicks into cooling mode and the process is reversed, as heat is extracted inside and released outside. This non-combustion process of moving heat from one place to another provides several potential benefits to society: Heat pumps support the megatrend toward decarbonization. They replace fossil-fuel heating with high-efficiency technology. They can be paired with lower-global-warming-potential (GWP) A2L refrigerants—such as R-454B and R-32—to further increase environmental benefits, while offering similar performance to the legacy R-410A. They offer the ability to tap into alternative energy sources, such as industrial waste heat as well as heat sourced from the air (ambient), ground (geothermal), or lakes/ponds (water). Meeting today’s needs—these aren’t your grandfather’s heat pumps Heat pump technology has been commercially available and in use since the 1950s. Early versions of heat pumps were essentially reversible air conditioning units, and most used traditional refrigerants—like R-22 and, more recently, R-410A. These units performed well and operated safely using lower-toxicity, nonflammable (A1) refrigerants. However, they were known to sometimes struggle at lower ambient temperatures. As often happens in the world of science and technology, challenges drive the search for solutions. Today, we’re seeing innovations that result in efficient, effective cold-climate heat pumps that optimize various components, such as compressors, heat exchangers, expansion valves, and their controls. Thanks to these innovations and others, the U.S. and other countries are experiencing broader heat pump adoption and, in turn, supporting progress toward decarbonization.  Heat pump technology has been commercially available. Increasing heat pump accessibility and viability in more places and spaces is also critical to the HVACR industry’s commitments to the environment—and its need to heed regulations advancing the transition to systems reducing climate impact. Emerging systems use mildly flammable (A2L) refrigerants. They are similar in design to legacy systems and include modifications to mitigate risks associated with the change to A2Ls. Where things are headed—heat pump technology is just getting started Even with the significant advances we’ve seen in colder-climate heat pumps, there is still untapped potential in terms of what the technology can achieve. We can expect to see continued innovation as end-user needs and environmental priorities continue to evolve. Some foreseeable growth areas for heat pumps include: Traditional applications—that is, moderate climates Expansion into nontraditional climates—heating in very cold climates and cooling in hotter regions Domestic water heating, replacing fossil-fuel systems Leveraging a variety of heat sources—geothermal, air-sourced, and water-sourced Harnessing waste heat generated by energy-intensive industrial processes Use of lower-GWP A2L refrigerants System optimization will also drive greater use of lower-GWP A2L refrigerants, such as R-454B Supporting these growth areas will be innovations that optimize high-performance, high-efficiency delivery of extracted heat, using a combination of traditional and new split-ducted, ductless/mini-split, and mono-block technologies. System optimization will also drive greater use of lower-GWP A2L refrigerants, such as R-454B, while limiting the use of highly flammable refrigerants such as R-290. Refrigerant selection will also play an increasingly important role and may offer additional opportunities for application-specific technology. As heat pump applications expand, we can expect to see greater focus on selecting the optimum refrigerant to use as the working fluid. Criteria will weigh system design, operating conditions, and other priorities against key refrigerant properties: Physical—boiling point, vapor pressure, density, and material compatibility Thermodynamic—cooling/heat capacity, energy efficiency, pressure-enthalpy (PH) curves Environmental—ozone depletion potential (ODP) and global warming potential (GWP) Safety and health—flammability and toxicity Conclusion: There’s strong and ample reason to “stay pumped” Over the past several years, members of the HVACR industry have enthusiastically embraced new heat pump solutions. Evolving heat pump technology and expanding applications will continue as the industry progresses along the path of more energy-efficient, lower-GWP, and more sustainable new-generation and next-generation heating and cooling. This, coupled engineering and science that leverages untapped heat pump potential, will mean more opportunities for HVACR contractors to deliver new options to the markets they serve. With a strong understanding of their customers’ individual heating and cooling needs, climate challenges, and sustainability goals, contractors can confidently select the best heat-pump refrigerant solution.

From temperate climates that reach mid-90 F in June and mild winters allowing people to be outdoors without jackets to the “May flowers” that bloom in early March, it’s evident that society is experiencing World Refrigeration Day’s 2024 theme: “Temperature matters.” In addition to driving climate change, global warming is driving changes in how people live and how industries adapt and innovate to support new dynamics. This is especially true for the HVACR Industry. Over the past several years, contractors have been busy installing and servicing cooling systems in climate zones that historically haven’t needed them. There’s a major focus on achieving more energy efficiency and lower water consumption in cooling the world’s escalating number of data centers.  Impact on HVACR Industry There’s also increased demand to conserve water in cooling towers and/or adiabatic condensers and for elevated indoor environmental quality (IEQ) to improve health and productivity. A few examples show how rising global temperatures are impacting the HVACR industry These few examples demonstrate how rising global temperatures are impacting the HVACR industry. Sharing a huge part of the spotlight of industry solutions are refrigerants, which now need to work harder than ever to keep people comfortable and foods, beverages, and pharmaceuticals at proper temperatures. And they must do so without contributing to global warming and other environmental concerns. Refrigerant priority #1: lower GWP Assessing refrigerants for their ability to address climate change concerns starts with their global warming potential (GWP). That’s why attention has turned to A2Ls, which offer significantly lower GWP than legacy refrigerants. The three “big players” in the A2L arena—R-454A, R-454B, and R-454C—are now being selected for new-generation equipment solutions in various HVACR applications. A look at GWP reduction in a sampling of these applications tells the story: R-454A and R-454C can provide a 94% to 96% reduction in GWP as an alternative for R-404A, while offering similar performance Applications that historically would use a new R-410A unit can transition to R-454B, resulting in a 77% reduction in GWP. The industry is also choosing HFO-1234yf, an A2L currently used in air conditioners in 95 million vehicles on U.S. roads. HFO-1234yf has an AR4 GWP of 4 and is also used as a blend component in Chemours A1 and A2L products. Although A2Ls are for new equipment only, lower-GWP A1 refrigerant solutions can help in retrofits. For most applications using a higher-GWP HFC in an existing system, there’s likely a lower-GWP HFC/HFO blend for retrofit applications Other refrigerant priorities Of course, the value of a refrigerant is based on more than just low GWP Of course, the value of a refrigerant is based on more than just low GWP. The true innovation in refrigerant development lies in striking the optimal balance between environmental impact and performance for a diversity of applications. For example, after developing what are now considered three major players in the future of refrigerants—Chemours Opteon™ XL40 (R-454A), Opteon™ XL41 (R-454B), and Opteon™ XL20 (R-454C)—our chemists remain in the labs and work with pioneering industry partners to lower GWP even more, without compromising other properties. It’s important to consider how well a refrigerant addresses several key factors: Low GWP and zero ozone depletion potential (ODP) Reduced energy consumption Circularity—the ability to be recovered, recycled, and reclaimed Lower operating costs over the lifetime of equipment Safety—for everyone from technicians to end users Overall performance—measured by capacity, reliability, and efficiency Can be serviced by a large existing workforce of trained technicians Responsible manufacturing focused on reducing carbon emissions Availability and supply chain strength A2L refrigerants have been designed with these factors in mind, raising the bar in terms of performance and support for environmental priorities. Addressing climate zone challenges In addition to solutions designed for today’s many residential, commercial, and industrial cooling and refrigeration applications, the industry needs a full toolbox of systems, components, and refrigerants to meet—in a highly efficient manner—the challenges of cooling and heating in various climate zones. These range from Zone 1, which is very hot, humid, and dry, to the subarctic Zone 8 ASHRAE divides the U.S. into eight major climate zones. These range from Zone 1, which is very hot, humid, and dry, to the subarctic Zone 8. In between these two extremes, we find various levels of heat/cold, humidity, and dryness. These climate zones provide system engineers with guidance for choosing the best designs—including refrigerant selection—so that each zone can be equipped with the appropriate system, optimized for year-round capacity, efficiency, reliability, and more. New-generation heat pumps For example, the high heat and humidity of a tropical climate put heavy demand on cooling equipment—from air conditioners to refrigeration systems. These cooling systems are likely to run most of the year, so choosing a highly energy-efficient option is paramount. By contrast, we have zones with overall colder ambient temperatures. Heat pumps must be properly sized to ensure occupant comfort. Cooling systems in these climates have limited use during the year, but they must perform reliably when needed. In climates where heating buildings take priority over cooling them, we’re finding a significant transition from traditional AC-only units to new-generation heat pumps. Heat pumps must be properly sized to ensure occupant comfort and keep the heat pump from “struggling” to control humidity when operated in AC mode. Choosing refrigerant solutions There is no question the world’s temperature is on the rise. According to the National Oceanic and Atmospheric Administration, since 1982, the rate of the Earth’s warming has risen approximately 0.36 F (0.20°C) per decade—more than three times the average rate of all previous decades measured. The 10 warmest years on record all occurred in the past decade. And 2023 was the warmest year on record for North America, South America, and Africa, as well as the second warmest for Europe. As climate change continues to warm up winters and heat up summers, refrigerants will play an increasingly important role in “cooling down” people and products and helping to reduce the impact that industry and society have on “heating up” the planet. Everyone can do their part by understanding that temperature matters, then choosing refrigerant solutions that have lower GWP, support other environmental needs, and offer the right combination of performance attributes for a given climate zone.

Johnson Controls’ Advanced Development Engineering Center (JADEC) in New Freedom, PA., about 25 miles from Philadelphia, highlights and demonstrates the company’s capabilities related to development, testing and manufacturing.  The 357,000-square-foot facility is an advanced engineering and testing facility for water-cooled chillers, air-cooled chillers, air handlers, compressors, and heat pumps. Much of the development in the facility centers on advancements in a critical vertical market for the HVAC industry – data centers. Big challenge  Data centers are a big challenge – and a huge opportunity – for the HVAC industry. “You cannot ignore the tremendous growth opportunity in this vertical,” says Todd Grabowski, president, Global Data Center Solutions for Johnson Controls. Unlike other verticals that are more dominant in certain geographic regions, data centers are growing everywhere globally – and at a breathtaking pace. “As a growth company, it is critical that we have solutions to handle the growth and serve the customers in the data center market,” says Grabowski. Performance of various components Testing options at JADEC include testing the performance of various components Testing options at JADEC include the ability to test the performance of various components in a controlled environment that approximates how they will operate in the customer’s real-world setting. There are more than 20 testing labs available at the JADEC campus, covering some 250,000 square feet.  “We want everyone to understand the unique position Johnson Controls is in to use our technology and our manufacturing scale to accomplish desired outcomes,” said Grabowski. Non-compressor solution  JADEC displays the full breadth of what they offer, including a non-compressor solution using direct evaporative cooling and an air-cooled unit that uses a screw compressor or a magnetic-bearing centrifugal compressor. Also included are various water-cooled chillers.   Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Customers are assured of getting a fully engineered and supported solution from Johnson Controls (e.g., no third-party compressors). Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Colocated data centers  Grabowski emphasizes that each customer installation has site-specific needs that require unique solutions that Johnson Controls seeks to fulfill. The company works closely with data centers, including those operated by “hyperscalers” such as Amazon, Microsoft, Apple, and Meta, and colocated data centers that rent space and capacity to customers based on their growth and needs. Colocated data centers come in a variety of sizes and types; some of them are operated by companies such as Equinix and NTT. Data center solutions Sustainable methods include the use of refrigerants with ultra-low GWP The sustainability of data center solutions is a bigger issue than ever, given the sheer volume of data centers being built to handle the world’s growing computational needs. Sustainable approaches include the use of refrigerants with ultra-low GWP, and water-free systems that do not require higher costs or create higher demands on a locality’s water infrastructure. Magnetic bearing centrifugal compressors are more energy-efficient because no friction is lost in the compression; also, the equipment is quieter. Impact on global electricity demand “Sustainability has always been an important aspect, and now it is critical in 2024 and beyond,” says Grabowski. Because data centers are huge consumers of energy, they can put more strain on the electricity grid and have a big impact on global electricity demand. Lowering energy usage helps to address the challenge.  “We want to contribute to energy efficiency, be good stewards of water, and reduce noise,” says Grabowski. Increasing the challenges are the proliferation of new artificial intelligence (AI) chips, more common in newer data centers, which need more power and create more heat than older chips.   Advantages of water cooling  The liquid contained in a cold plate on top of the chip is denser than air and accept more transferred heat Closed-loop liquid systems are used to cool individual chips, an application that does not cause a strain on local water supplies. The liquid contained in a cold plate on top of the chip is denser than air and can accept more transferred heat.  However, chillers and cooling towers lose water through evaporation and can strain local water supplies. Johnson Controls is researching and testing systems that provide the advantage of water cooling without losing excess water to evaporation. Air-cooled systems  In contrast, air-cooled systems can cool chips to a point, but may not provide enough cooling for high-density chips. Johnson Controls provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons.  “As chip technology evolves, the way you cool, secure and automate the entire data center changes as well,” says Grabowski. “Companies such as Johnson Controls must keep up with evolving trends and provide unique solutions.” As chips become denser from a heat-generation perspective, systems must be optimized from a footprint and energy standpoint.  JCI provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons. Technological solutions “As chip density increases, we will have technological solutions ready for the next generation of chips when they come out,” adds Grabowski.  Johnson Controls is also involved in developing new approaches to managing the heat from data centers, such as the possibility of recapturing the heat and circulating it into a district-heating system for a nearby community, university, or hospital. A more widely deployed approach in Europe, the concept of district heating is gaining acceptance in the U.S. market. {##Poll1725623180 - What is the biggest challenge the data center market presents to the HVAC community?##}

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

Humidity can influence employee health and productivity in the workplace. Humidity, temperature, and ventilation all work in concert to create a healthy indoor environment that supports overall occupant well-being. “Dry indoor air can cause discomfort in the form of dry skin, eyes, and throat for staff and visitors,” says Jennifer Montville, Director of Marketing at DriSteem, a manufacturer of humidification systems. Air-related health issues “There are real costs associated with health-related issues caused by dry air, including a higher occurrence of infections and increased rates of staff absenteeism?”  Maintaining a comfortable work environment, including the correct humidity levels, prevents respiratory issues and reduces the spread of illnesses, ensuring a healthy working environment and boosting productivity and efficiency, says Montville.  humidity levels Humidified spaces help keep facility costs down by improving thermal comfort at lower temperatures Maintaining humidity levels between 40% and 60% RH is ideal for mitigating virus transmission, she comments. Humidified spaces feel warmer and are more comfortable for employees, which in turn increases their productivity with improved concentration and less fatigue. It also helps keep facility costs down by improving thermal comfort at lower temperatures.  dehumidifiers Employing dehumidifiers to keep humidity levels from rising above that 60% RH threshold is also important. Removing excess moisture from the air reduces distraction from unpleasant smells or health issues caused by mold, mildew, or fungi that thrive in moist environments. All the ways that proper humidity levels affect employee health and productivity in the workplace also contribute to increased customer satisfaction in office and retail spaces, says Montville.  preventing product issues “We all prefer to spend time in places where we feel physically comfortable,” she says. “Customers in offices and retail spaces are no different. When physical comfort is not an issue, we are likely to spend more time and engage more deeply.” Well-managed humidity levels also help to prevent product issues such as shrinkage, warping, or degradation due to moisture fluctuations. Food quality is particularly impacted by humidity levels. In a retail store, this can translate to spending more time shopping in a store and a more positive opinion of the products being considered.  recommended indoor relative humidity level Keeping relative humidity levels within the range ensures the health and safety of building occupants The recommended indoor relative humidity level ranges from 30% to 60% RH, according to guidelines published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Keeping relative humidity levels within this range ensures the health and safety of building occupants without promoting mold growth or other indoor air quality issues.  air quality goals With that said, the type of indoor space, air quality goals, and how the space is used will determine the best relative humidity levels for each facility, according to Montville. Machinery and sensitive electronic equipment are vulnerable to low or fluctuating moisture levels. Static electricity buildup and electrical malfunctions are among the potential consequences of inadequate humidity control.  precise humidity control Many industrial processes depend on the consistent quality of materials, and fluctuations in relative humidity (RH) can result in less-than-ideal inputs which in turn impact the quality of final products. From preventing mold growth, spoilage, and texture deterioration in food processing to safeguarding medication stability, efficacy, and safety of pharmaceuticals, precise humidity control is critical to achieving intended results.  Optimal RH levels Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness Maintaining appropriate humidity levels is essential for infection control. Optimal RH levels can inhibit the growth and transmission of airborne pathogens, such as viruses, bacteria, and fungi. Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness of respiratory tract mucous membranes in trapping and neutralizing pathogens. Conversely, dry indoor air impairs these defenses, increasing susceptibility to respiratory infections.  humidity control systems Investing in commercial humidity control systems, such as those offered by DriSteem, can effectively regulate RH levels within facilities. “These systems provide flexibility and precision in catering to specific humidity needs across different areas within the facility,” says Montville. Whether integrating humidity control solutions in existing structures or implementing them in new buildings, factors such as the type of indoor space, energy source, required maintenance, and capacity determine the best technology for each building, she says.

With 53 men on the Jacksonville Jaguars roster, practicing 5 to 6 days per week for 10 to 12 hours a day, the demand for hot water must be enormous. As the choice for the team’s practice facility’s hot water storage and water heating capabilities, we happen to have the deets. How about 1,880 gallons of storage capacity and 2,400,000 btu/hr heating the water?  Miller Electric Center The Miller Electric Center is a new state-of-the-art practice facility in downtown Jacksonville that serves as the Jaguars’ football operations headquarters. The 120 million dollar facility is 125,000 square feet and includes locker rooms, training and medical facilities, office space, and a draft room. It also features two full-size grass practice fields and one indoor field, along with shaded public viewing stands, concession areas, and a team store.  Big men need big spaces  Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze Luckily, Lochinvar’s Armor Condensing water heaters are up for the job. The Armor’s stainless steel heat exchanger delivers hot water at 98% thermal efficiency and modulates at a 10:1 turndown ratio. That means the units can fire as low as 10% of their total capability and modulate up to 100% when the demand is greatest. The Jag’s facility has 3 of the AWH0800NPM units installed providing the ability to cascade which ensures the units operate with equal runtime and extends the life of the heaters. The Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze – which is nice in Florida. Lock-Temp Round Jacketed Storage Tank With a proven storage vessel like the Lock-Temp Round Jacketed Storage Tank, making sure the stored hot water is ready for delivery is a given. These tanks have the exclusive Lock-Temp baffle that keeps water evenly stratified and the 80% draw factor allows almost the entire capacity to be used at the designated temperature.  installation and commission With the help of a local manufacturers’ rep firm, Harry Warren, the installing contractor, Touchton Plumbing out of Jacksonville reported that the whole experience went off without a hitch. “The installation went extremely well, and the units have been working without fail through the first year of the facility being in use,” said Parker Touchton, project manager. The equipment was installed and commissioned according to schedule and is said to be performing as promised and at the end of a 12-hour practice, there’s no room for disappointment. 

To offset the cost of tenants’ monthly electric bills and provide prospective residents with high-quality HVAC upgrades that prioritize comfort and performance, Samuels Associates, owner of the Fenway Triangle luxury apartments, sought a new, building-wide heating solution that was not only cost-effective but also added a modern touch to the building’s extravagance. QMark® MUH-Pro+ and CU900 electric heaters with SmartSeries® Plus (SSP) digital BACnet thermostats from Goodyear HVAC Sales proved to be the ideal solution. Heat in a contemporary design “From their energy efficiency, quiet operation and low maintenance to the fact that they can be controlled individually for personalized comfort, electric heaters offer several benefits in apartment buildings,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products® (MEP). “Delivering supplemental comfort heat in a contemporary design, these heaters are ideal for a variety of spaces including school hallways, church vestibules, transportation terminals, stairwells, entrances, lobbies, mechanical rooms and more.”  Installing Heaters while Maintaining esthetics Buildings boast modern frills and discreet and esthetically good HVAC plans that act quietly Steps away from the iconic Fenway Park, the Fenway Triangle is an 891,000-square-foot complex comprising more than 570 luxury apartment units, as well as an eclectic mix of national and local retailers, restaurants, shops and green spaces. Since opening in 2006, the building needed to address issues with its HVAC systems and controls, which were leading to high monthly electric bills. The culprit? More than 50 outdated competitor electric terminal heaters, which offered only on/off controls and needed to be operated manually. If the maintenance team forgot to shut off the heaters, "The Fenway" would incur the cost of each heater running at full capacity at a rate of about 27 cents per kilowatt-hour. Another challenge facing Fenway Triangle: The emergence of new luxury apartment complexes. These buildings boast modern amenities and discreet and esthetically pleasing HVAC systems that operate quietly. They pose significant competition for “The Fenway”, as tenants increasingly prioritize indoor air quality (IAQ) and HVAC performance when selecting their luxury residences. To remain competitive in the luxury apartment market, investing in HVAC upgrades to replace outdated equipment is imperative. QMark MUH-Pro+ and CU900 electric heaters  Heaters were installed in elevator banks, stairwells, worker lounges, hallways, and facility To combat the rising cost of heating each unit within the building, MEP’s local Sales Representative, Goodyear HVAC Sales, worked with HVAC distributor Equipment Direct Sales, Inc. (EDSI) to provide the client with energy-efficient QMark MUH-Pro+ and CU900 electric heaters from Marley Engineered Products. Designed to maintain occupant comfort and a comfortable environment, the heaters were installed in various elevator banks, stairwells, employee lounges, hallways and inside the building’s recently upgraded building management system (BMS) room.  “Equipped with SSP digital thermostats that provide connections to BACnet MS/TP BMS for easy control and monitoring, the MUH-Pro+ and CU900 units only run when directed by the internal schedule of the BMS,” said Matthew Goodrich, President of Goodyear HVAC Sales. “Use of the BMS saves time and reduces personnel costs by eliminating the need to travel to the heater site. And, if a BMS is not available, the maintenance team can simply use the built in seven-day programmable scheduling feature.”  New electric heating units Cost-Effective Heat for Unmatched Comfort and Lower Monthly Bills In tandem with EDSI, Goodrich and his team installed several brand-new electric heating units in The Fenway’s BMS room to provide cost-effective warmth without taking up floor space or creating a tripping hazard.  “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Goodrich. “In fabricating this solution for the client, our dedicated team and the coordination of skilled contractors transformed this building into a space that harmonizes comfort and elegance and exemplifies the blending of form and function.”  Full control of the entire heating system The thermostats include features that allow the building’s maintenance team to monitor each heater The success of the project resulted in an extremely satisfied customer. Already, the SSP thermostats have provided cost savings by turning on the heaters only when needed, resulting in less electricity usage throughout The Fenway. Additionally, the thermostats include features that allow the building’s maintenance team to monitor each heater individually from within the BMS room, granting them full control of the entire heating system and eliminating the daily trips previously needed to turn each heater on and off.  “We’re already seeing the savings associated with the upgraded controls,” said John Belmonte, Head of Trilogy Operations for the Fenway Triangle. “Being able to control over 40 heaters locally allows our team to focus on tenant needs without being bogged down by the time it takes to touch each individual unit. We’re eager to work further with the Goodyear team on other buildings in the neighborhood.” Innovative approach and exceptional achievements To acknowledge the innovative approach and exceptional achievements demonstrated by the Goodyear team in overcoming the challenges faced during this project, Marley Engineered Products awarded Goodrich the 2024 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. “This award for excellence in solution design embodies the spirit of Herring, who left a lasting legacy of designing creative solutions for specialized applications, was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Director of Sales for Marley Engineered Products. “Matthew and his team at Goodyear perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”

To adequately heat the 111 Murray Street residential skyscraper in New York, the owner sought an effective way to maintain the aesthetic of the mostly glass building without being obtrusive to its design. Custom convection style heaters, mounted in the building’s millwork by Faber Industrial Technologies, proved to be the game-changing resolution. “Convection heaters provide warmth and heat to a specific area or room by circulating air and heating it using a highly efficient electric element,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products. He adds, “Designed for quiet, controlled comfort, they are ideal for both residential and commercial applications, including living rooms and bedrooms, offices, hallways, lobbies, conference rooms, retail stores and buildings with floor-to-ceiling windows.” Installing heaters while maintaining aesthetics 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums Located in the Financial District and Tribeca neighborhoods in Lower Manhattan, 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums and 2,100 square feet of retail space on the ground floor. Due to mechanical constraints exacerbated by the building’s slim design, hot water was not available in most of the upper residences, rendering hydronic heating systems impractical. Therefore, the client requested Berko ASL3 convector heaters from Marley Engineered Products to be installed for elegant, supplemental comfort for heat loss, condensation prevention and continuous warmth throughout each condo. The challenge, however, came from their preference to keep the heaters hidden for aesthetic reasons. “The varying heights and angles of the millwork in each condo limited our ability to install the heaters directly where we wanted them,” said Christopher Smith, a Heater Manufacturing Representative with Faber Industrial Technologies, adding “Therefore, we needed a custom design that enabled us to mount the heaters properly while also keeping them out of sight.” Hidden Heat for Unmatched Comfort and Elegance The solution involved fabricating and supplying custom dual inlet convector heaters, which were then mounted within the millwork of each condominium unit. Using a thermocouple array, the engineering team at Marley tested the Berko ASL3 convectors – at 125 watts per foot and 120V – inside a customer-supplied demo millwork section sent from New York City. After making some adjustments to the design, thermal couplers were utilized on both the heaters and their enclosures to ensure their surface temperatures were within Marley Engineered Products’ limits to pass a UL site inspection. Berko ASL3 convector heaters The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units Next, Smith coordinated with the electrical and mechanical contractors on-site to fit the heaters into each condo’s temperature control system using power relays. The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units. “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Christopher Smith, adding “In fabricating this ‘invisible solution’ for the client, our dedicated team and the coordination of skilled contractors transformed these condos into spaces that harmonize comfort and elegance and exemplify the blending of form and function.” Berko ASL3 convector heaters The success of the project not only resulted in an extremely satisfied customer, but also left the contractors pleased with the uninterrupted delivery and installation of the heaters. They were further impressed when the custom heater and millwork system passed the UL site inspector’s test after just one evaluation. To acknowledge the innovative approach and exceptional achievements demonstrated by the Faber team in overcoming the challenges faced during this project, Marley Engineered Products awarded Smith the 2023 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. Solving unique heating or ventilation problems “This award for excellence in solution design embodies the spirit of Herring, who was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Acting Director of Sales for Marley Engineered Products. He adds, “Chris and his team perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”

Sophisticated temperature control using Fujitsu General Air Conditioning UK technology is delivering the best possible growing conditions for a vertical farming enterprise in Northamptonshire. Vertical farming involves growing food indoors on multiple levels, in vertically stacked layers, using UV lighting. With arable space increasingly coming under pressure from urbanization, the technique aims to provide an efficient and sustainable source of food into the future.  energy and resource-efficient Vertical Future says its systems use up to 98% less water compared to traditional farming, are energy and resource-efficient, and can grow the same amount of produce in 1% of the space when compared to traditional methods. The installation was carried out by CSL Air Conditioning with equipment supplied by distributor Oceanair.  monitoring and control technologies Darren James, Director of Vertical Future, said, “We deliver advanced growing solutions tailored to an industry that demands unparalleled precision and control. Our systems integrate sophisticated monitoring and control technologies, ensuring the optimum growth environment to maximize crop quality and yield." “I was extremely impressed with the combined work of both Fujitsu and Oceanair on this project." choosing equipments "Both companies attended the site in tandem so that they could come up with the best option for this project in loadings and efficiency, and choose the relevant equipment within the area where we could install the systems." “This meant more than one site visit but they kept me informed throughout the design stage of the project and it has worked wonders. The site has been up and running for over 12 months with no issues.’’  Controlled Environment Agriculture (CEA) technology By monitoring every aspect of the environment, it can achieve the best possible yield For the installation at Syan Farms in Horton, CSL Air Conditioning chose equipment from Fujitsu to meet the precise requirements of the customer and end-user. Electrical installation was carried out by a third party. Syan Farms uses Controlled Environment Agriculture (CEA) technology, which sets the temperature, light, and humidity within each growing stack. By monitoring every aspect of the environment, it can achieve the best possible yield and ensure crops are never affected by poor weather conditions or land damage. addressing air conditioning challenges Dave Crate from CSL Air Conditioning, said, “The biggest challenge is designing a system that can distribute air efficiently across the growing area." "We have developed a solution with all air conditioning units installed at a high level, with cool air sinking across the growing pods and any heat rising into the units. The wall mounts are positioned perpendicular to the growing racks to deliver air across the vertically stacked pods.’’  Fujitsu 22kW High Static Duct Units The ducted units are mounted centrally, and each uses a flexible fabric duct sock to distribute air evenly Oceanair supplied CSL with the equipment needed to keep the growing area at a constant 23°C. It was also crucial to design a system which avoided high-velocity air movement in the 30m2 space, as the plants require conditions as close to natural as possible. Two Fujitsu 22kW High Static Duct Units are paired with 22kW HP Inverter Condensers. The ducted units are mounted centrally, and each uses a flexible fabric duct sock to distribute air evenly along the center of the warehouse. These units work alongside eight Fujitsu 9.4kW Inverter Heat Pump Condensers, connected to eight 9.4kW Wall Mount Units. single controller operation The two groups of four systems, operating off a single controller, are sited at high levels on facing walls perpendicular to the growing racks to prevent excess air movement. Tony Holland of Oceanair said, “We know from long experience the capabilities of the Fujitsu kit and were confident that it was the correct choice for Vertical Future at Syan Farms." “It was a new experience to work out climate control loadings for plants rather than people but working as a team of manufacturers, distributors, engineers, and end users, we came up with a grid system to make sure each section had the correct loading to do the job and the proof of the warehouse now up and running and working to its full capacity is a testament to all parties concerned.”  Fujitsu 6.8kW Multi Condenser The installation marks a significant leap forward from the container-based modules with localized cooling Elsewhere on site, a multi-split system consisting of a Fujitsu 6.8kW Multi Condenser connected to two 3.4kW Wall Mount Units and a Compact Cassette serves the entrance, offices, and meeting area. The project is the first of this size for Vertical Future and further sites are in development. For Syan Farms, the installation marks a significant leap forward from the container-based modules with localized cooling used previously.  Food security Kelly Bullivant, Distribution Account Manager at Fujitsu General Air Conditioning, said, “Food security is becoming increasingly important and we are proud to be able to contribute to the development of vertical farming." "Our equipment is ideally suited to the precision needed for an installation of this type.’’

When the Florida Keys Aqueduct Authority opens its upgraded desalination plant on Stock Island, Danfoss high-pressure pumps and energy recovery devices will radically improve the energy efficiency of a SWRO plant that plays a central role in the Florida Keys water supply strategy.   The Florida Keys Aqueduct Authority (FKAA) supplies 20 million gallons of potable water per day (75.7k m3/d) to its nearly 80,000 customers in the Florida Keys. While most of the water is normally sourced in aquifers, FKAA also operates two seawater reverse osmosis (SWRO) plants for emergency purposes and as a supplemental supply in periods of high demand. FKAA initiated the SWRO plant upgrade FKAA initiated the upgrade of one of these plants, the Kermit H. Lewin Water Treatment Plant located on Stock Island, to increase its capacity, make it more resilient to hurricanes and rising flood levels, and improve its energy efficiency. Since opening in 1980, not only have guidelines for storm protection of such critical infrastructure changed significantly, so has the potential to save on the energy required by desalination. Designed to withstand future floods and hurricanes With sustained winds above 157 mph, such storms can cause severe damage to everything in their path To improve resiliency to extreme weather events in the low-lying Florida Keys, the entire site and facility have now been upgraded to withstand Category 5 hurricanes, the most dangerous level of tropical storms. With sustained winds above 157 mph (252 kph), such storms can cause severe damage to everything in their path. Accordingly, the refurbished facility lifts all electrical and mechanical equipment above the base flood elevation and the expected sea-level rise anticipated by 2060, effectively placing the plant’s desalination operations on stilts to mitigate the risk of severe flooding. improve the plant’s energy efficiency Another key goal of the upgrade was to improve the plant’s energy efficiency at the same time as doubling its production capacity from 2 MGD (7,500 m3/d) to 4 MGD (15,000 m3/d). To bring the refurbished plant up to date and reduce its financial and environmental costs, Carollo, a major U.S. engineering firm specializing in water and wastewater facilities, specified the latest axial-piston high-pressure pumps to replace legacy centrifugal pumps and swapped out old turbines for the newest active isobaric energy recovery technology. Upgraded plant to consist of four RO trains This innovative high-pressure setup dramatically reduces the plant’s energy needs This innovative high-pressure setup dramatically reduces the plant’s energy needs. In the new Kermit H. Lewin Water Treatment Plant being built by Biwater, a world pioneer in water treatment, the RO process-specific energy consumption will be slashed from 25.6 kW/kgal (6.77 kWh/m3) to 8.6 kW/kgal (2.27 kWh/m3). With this improvement, the new plant will be among the most energy-efficient in its class, with significantly reduced electricity bills and greenhouse gas emissions. The upgraded plant will consist of four RO trains, each of which includes two Danfoss APP 86 high-pressure pumps and three Danfoss iSave 70 ERDs. Improvement in energy efficiency In addition to the dramatic improvement in energy efficiency, configuring each train with parallel high-pressure pumps provides additional resilience and other benefits: the smaller pumps are easier to lift and work on, and it is now affordable to keep a spare pump in stock. The new improved plant will come online in Q4 2024. The new Kermit H. Lewin Water Treatment Plant is located just north of the existing plant. Construction began in Q3 2021 and will be completed by Q2 2024. The plant is expected to be fully operational by Q4 2024.

Convoy of Hope is an international nonprofit based in Springfield, Missouri. Founded in 1994 by Hal Donaldson, the humanitarian organization strives to feed the world and end intergenerational poverty. Programs include training and equipping local farmers to create food security, feeding more than 533,000 children every school day worldwide, U.S. and international disaster response, and empowering women as entrepreneurs and in the workforce. Since its founding, Convoy of Hope has served more than 250 million people and provided more than $2.5 billion worth of supplies to those in need. tackling global priorities In 2021, Convoy of Hope’s leadership decided that building a new headquarters and training center would improve the organization’s ability to serve humanity. For the first time in its nearly 30-year existence, Convoy of Hope would bring staff together on one campus to tackle its global priorities. The new facility would be a point of pride in Springfield and connect team members in an inviting and comfortable setting.  culture of the humanitarian organization The building would reflect the culture of the humanitarian organization and demonstrate good stewardship Additionally, the building would reflect the culture of the humanitarian organization and demonstrate good stewardship of financial resources. “We’re a non-profit organization, so we don’t want to spend more than we need to. We need to be able to take care of the heating and cooling needs in a way that’s efficient and cost-effective," said Ethan Forhetz, Vice President of Public Engagement, at Convoy of Hope. Project highlights Convoy of Hope’s headquarters is a 200,000-square-foot, modern, industrial-styled, open-concept, multi-use facility. The building houses a large atrium, auditorium, cafeteria, dining room, kitchen, open office spaces, and private offices. More than 280 of the organization’s 500-plus total employees work at the facility daily. The project team, assembled in 2021, collaborated from the design phase through the grand opening in 2023. Installation and project management Buxton Kubik Dodd, Inc., a full-service design firm in Springfield, did the architectural design, interior design, and mechanical engineering. Knight Heating & Air Conditioning, a local, family-owned HVAC contractor, did the installation and project management with support from Fields Mechanical Systems, a local LG-applied representative firm. “We try to recommend a product to the customer that has good local representation. It usually boils down to who supports a product the best. So that’s why we recommended LG,” said Chris Knight, Vice President, of Knight Heating and Air Conditioning. Challenges The heating and cooling system would need to satisfy diverse comfort requirements simultaneously Load diversity was the project team’s most significant challenge. Comfort requirements in the multi-use building vary by each space’s purpose, solar orientation, time of day, glazing, and whether the space is on the perimeter or interior. Southwest-facing offices have different heating and cooling needs than similar offices on the northeast side, as does the large, wide-open atrium versus the kitchen. On cold days when most of the building requires heating, some spaces still require cooling due to the facility’s glass frontage. The heating and cooling system would need to satisfy diverse comfort requirements simultaneously throughout the seasons, as Missouri’s weather ranged from intense heat to extreme cold. Acoustics, mechanical systems and designs The project team also considered acoustics while evaluating mechanical systems and designs. Convoy of Hope’s headquarters embraces an industrial aesthetic, which includes hard floors and concrete, exposed ceilings. With large, open spaces and few surfaces to absorb noise, a noisy HVAC system would disturb employees and reduce each space’s usability. The heating and cooling solution needed to operate quietly and fit in aesthetically. Concealing the HVAC equipment Given the facility’s size and profile in the community, Convoy of Hope tasked the project team with concealing the HVAC equipment so that it did not detract from the exterior appearance of the building. Thousands of cars pass the facility daily. The team rejected mechanical options that would have required extensive ductwork and equipment sitting in full view on the building’s lower roofs. Comfortable and seamless While hiding the equipment posed an engineering challenge, Convoy of Hope prioritized the building’s beauty While hiding the equipment posed an engineering challenge, Convoy of Hope prioritized the building’s beauty as part of being a good neighbor. “The ability to handle varying loads comfortably and seamlessly was the main goal of the project,” said Dylan Chorice, Principal Engineer, Buxton Kubik Dodd, Inc. Solution The project team decided that a variable refrigerant flow (VRF) system with heat recovery from LG would be the best and most cost-effective solution to meeting Convoy of Hope’s needs. “Early in the process, we knew LG was the partner we wanted to work with,” said Dylan Chorice, Principal Engineer, Buxton Kubik Dodd, Inc. Multi V 5 system LG’s Multi V 5 system uses comprehensive controls and outdoor units with inverters to vary compressor speeds and heating and cooling capacity based on occupant comfort needs and ambient conditions. Every outdoor unit connects to multiple indoor units, each serving a zone within the building. With LG’s inverter technology, the all-electric system uses minimal energy to move heat out of zones requiring cooling and transfer heat to zones that need heating. “What LG does for us here is allow us to meet the unique needs of our building’s individual spaces,” said Ethan Forhetz, VP of Public Engagement, at Convoy of Hope. Heat-recovery unit VRF systems typically reject indoor heat to the outdoors during cooling and operate in one mode at a time The project team specified an LG Multi V 5 system with a heat-recovery unit to solve Convoy of Hope’s load diversity challenge with simultaneous heating and cooling. VRF systems typically reject indoor heat to the outdoors during cooling and operate in one mode at a time: heating or cooling.  Adding a heat-recovery unit enables LG’s VRF system to transfer heat from zones in cooling mode and simultaneously use it to warm zones in heating mode. Increased efficiency and cost savings By repurposing heat instead of rejecting it, a VRF system with heat recovery increases efficiency and cost savings while keeping diverse spaces comfortable. For example, the Multi V 5 can cool Convoy of Hope’ssouthwest-facing offices and account for solar gain while using that heat to warm the building’s cooler opposite side. The technology also allows Convoy of Hope to customize setpoints for each zone based on individual and administrator preferences. Powered by the Niagara 4 Framework®, LG’sMultiSITE VM3 controls empower facility managers to visualize, monitor, and control the entire VRF system. Mid-static ducted units The project team installed mid-static ducted units in the areas with covered ceilings. In the open office spaces with exposed high ceilings, the project team installed LG’s DUAL Vane 4-way cassettes. The cassettes cover wide spaces and contribute to healthier air with a five-step filtration and purification kit. To better match the space’s aesthetic requirements, the team placed shrouds on the cassettes, giving the units a cloud-like look that fits seamlessly into the design. Compact refrigerant lines Multi V 5 solution supported Convoy of Hope’s aesthetic needs and reduce costs by requiring less ductwork The Multi V 5 solution also supported Convoy of Hope’s aesthetic needs and reduced costs by requiring less ductwork than alternative systems.LG’s VRF system runs very quietly. Convoy of Hope team members can focus on their work without complaints about comfort or mechanical noise. The Multi V 5’s long, compact refrigerant lines enabled the project team to tackle the facility’s exterior design challenges.  VRF outdoor units By installing the VRF outdoor units on the third floor’s roof, the project team kept the system out of sight to pass neighbors or people entering the parking lot. The refrigerant lines run from the upper roof and down the sides of the buildings to serve the lower floors without requiring units on the ground or the lower roofs. Result Convoy of Hope is currently listed among the top 50 organizations in the Forbes list of America’s Top 100 Charities. With its new headquarters and training center, the organization is positioned to continue and grow its humanitarian work. “It’s a brand-new building. It’s a big building. But it felt very homey right off the bat. I think a large part of that is because it’s very comfortable,” said Ethan Forhetz, VP of Public Engagement, at Convoy of Hope. Cost-effective operation LG’s Multi V 5 VRF system with heat recovery satisfies Convoy of Hope's requirements LG’s Multi V 5 VRF system with heat recovery satisfies Convoy of Hope's requirements across comfort, efficiency, acoustics, and aesthetics. The facility is a community showpiece that helps the organization keep faith with its financial supporters through cost-effective operation. “Convoy of Hope plans to be here for a very long time, so every dollar we can save on utility bills is another dollar they can put toward their mission, which is critically important,” said Dylan Chorice, Principal Engineer, Buxton Kubik Dodd, Inc.
