How can UK businesses effectively tackle the challenge of cooling commercial and industrial buildings? Cooling commercial and industrial buildings can be a challenge for UK businesses. In recent years, the spiraling energy costs have put pressure on businesses with regard to finding new and innovative ways to achieve the same result with less capital outlay and less maintenance. New system installs have sometimes been put on hold and maintenance schedules squeezed, leaving many businesses with the challenge of managing aging HVAC assets and deciding when and where to invest. Systems without regular maintenance can experience unpredictable downtime and parts availability is not always guaranteed. Evaporative Cooling Evaporative cooling is an alternative cooling method that not only offers higher energy efficiency Business owners will always wonder how they can improve the cost-effectiveness, ease of maintenance, and sustainability of systems their business needs. When it comes to cooling business premises, there’s a solution that not enough people know: Evaporative Cooling.  Evaporative cooling is an alternative cooling method that not only offers higher energy efficiency than alternative HVAC solutions but also has cheaper running costs. Since then, it has been our mission to develop and use this technology to tackle the cooling challenges in industrial processes. Cooling Challenges in Industrial Processes With regard to cooling, many industrial processes have a high heat gain, whereby the process itself generates heat which must be managed. There are numerous sectors where this is occurring, two prime examples from our customer experience are industrial-scale bakeries and plastic molding facilities. The production line may be operational 24 hours a day, seven days a week In an industrial-scale bakery using modern production methods, the production line may be operational 24 hours a day, seven days a week. The constant production of heat and steam from large ovens working to high temperatures must be managed carefully, especially given the health and safety requirements for food production areas. Heat gain from the industrial processes Plastic molding facilities manufacture a variety of end products from everyday items such as plastic bottles for household goods to more specialist storage and packaging products. In a plastic molding facility heat is used to mold the liquid plastic but chemical particles may also need extraction to maintain a safe working environment. Production in any of these facilities may be adversely affected by the heat gain in the process itself. Unplanned and unmanaged heat in any manufacturing facility has the potential to stop production resulting in a cascade of business interruption, lost revenues, damaged stock, and missed productivity targets. All potentially severe impacts for any business to consider. Plastic molding facilities manufacture a variety of end products. In addition to heat gain from the industrial processes, we should also note that UK air temperatures are rising, the top 10 warmest years for the UK since records began in 1884 have all occurred since 2002. As the UK continues to experience temperature rises and more seasonal fluctuations we need to look to those more experienced with warmer climates to optimize and improve our own approach to cooling these spaces. So, let’s consider the choices to cool large commercial and industrial spaces. Conventional air conditioning (AC) systems Cotton mills and textile plants were among the early adopters of the technological advancement Most of us will be familiar with conventional air conditioning (AC) systems but let’s review how they work: The first “modern” air conditioning unit was built by the American inventor Willis Carrier in 1902 and was used to control the temperature in the Sackett-Wilhelms Lithographing & Publishing Company in Brooklyn, New York. This innovation helped to control the paper dimension and ink alignment. Cotton mills and textile plants were among the early adopters with the technological advancement soon spreading across the world. Today a conventional AC unit removes heat and moisture from the air. It uses a chemical refrigerant to cool the air which is then re-circulated in the building. The same air is then filtered as it returns to the unit. Key Facts of Conventional Air Conditioning Temperature can be controlled. Air is mostly recirculated within the space or building. The resultant energy performance of the system can be negatively impacted by high external temperatures, i.e., the hotter the external temperature the greater the amount of energy needed to run the unit and maintain the desired temperature. Complete systems are expensive to install and maintain due to the more complex requirements associated with the refrigerants used within the units. The cost to run large systems is expensive resulting in high and unpredictable energy bills. Chemical refrigerants are used ultimately negatively contributing to climate change. Conventional air conditioning cannot be said to be a bad choice however, in our experience, it is more suited to smaller spaces with a defined use. Office spaces would be a good example of where air conditioning systems can still be a good solution albeit without the benefit of reduced running costs. A fantastic sustainable alternative to conventional air conditioning is an evaporative cooling system. Historically championed in warmer climate countries, the technology delivers several benefits over and above conventional and familiar air conditioning. Evaporative Cooling Solutions Fresh, filtered air enters the system and is pulled through a cooling pad Reflecting on global history, examples of evaporative cooling can be seen as far back as 1350AD. One case describes how in Cairo, Egypt, a building was purposely situated up-wind, to catch the air and let it flow down the building and across a fountain which increased the relative humidity and lowered the temperature of the surrounding air. A fascinating early adoption of the evaporative cooling effect. Evaporative cooling systems as the name suggests use evaporation to cool the air; surprisingly no chemical refrigerants are involved in this process. Fresh, filtered air enters the system and is pulled through a cooling pad where the heat is absorbed. The resultant cooled air is distributed throughout the space via ducts. Key Facts of Evaporative Cooling Temperature and humidity can be accurately controlled. Indoor Air Quality (IAQ) is improved because of the introduction of 100% fresh outside air this in turn improves employee comfort, health, and well-being and supports good productivity. Cooling performance is improved with increasing external temperatures–efficiency rises along with the temperature. Initial capital outlay costs are relatively low, in comparison to a like-for-like conventional air conditioning system. Running costs are low, lowering energy bills and energy dependence. Based on the evaporation principle and using only water to cool, combined with the lack of chemical refrigerant make evaporative cooling a responsible, energy-efficient, and sustainable choice for cooling your industrial or commercial workplace. Lowering Carbon Footprint with Evaporative Cooling The carbon footprint is a method of determining environmental impact Lower your business carbon footprint with an evaporative cooling system. When measuring a carbon footprint, it’s the amount of carbon dioxide directly or indirectly produced. The carbon footprint is a method of determining environmental impact. If an industry appliance uses a low level of electricity, it minimizes the environmental impact. Evaporative cooling systems can contribute to lowering the carbon footprint of your factory and warehouse in the following ways: Evaporative cooling products can use up to 82% less energy compared with conventional air conditioning. This is a huge saving both initially and across a lifespan of more than 15 years. Evaporative coolers also consume up to 30% less water than conventional AC systems despite relying on water to provide evaporation for the cooling effect!  Addressing Industrial Hotspots In addition, industrial manufacturing workplaces often have hot spots that are uncomfortable to work in and those spaces are not just hotter than the rest of the building, but hotter than external ambient conditions. Evaporative cooling may be used to “spot cool” these hot spots and therefore reduce the need for the multiple units that would be needed to cool the entire space. Evaporative cooling is a proven technology perfect for all kinds of HVAC applications across multiple industries, this includes manufacturing plants and commercial warehouses. When cooling these large areas, evaporative cooling is repeatedly more cost-effective than traditional air conditioning. The primary benefit being the initial capital outlay to design and install the system is lower than conventional air conditioning. Secondly, the day-to-day running costs are again less owing to the reduced energy demand by the sophisticated technology used in these coolers. Unusually, these cost savings are also underpinned by the eco-friendly credentials of the technology, potentially contributing to reducing the carbon footprint of your business. This can be further enhanced by installing supportive clean energy technology such as solar power.

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.

Advanced heating, ventilation, air-conditioning, and refrigeration (HVACR) systems have always been essential to healthcare. However, the need for clean, fresh air at the right temperature and humidity within clinical settings has never been made clearer during the COVID-19 pandemic. It illustrated the importance of effective HVACR systems in healthcare due to their ability to improve air quality, patient outcomes, and infection control measures.  The need for change  Many current HVACR systems are outdated. Their reliance on direct on-line motor connection and mechanical methods to regulate fans, pumps, and compressors leads to inefficient energy use, generating higher costs. However, switching from manual methods to variable speed drives (VSDs) to regulate motor speeds can save as much as 25% in HVACR energy use, reducing operational costs in the process, and improving air quality control. The adoption of advanced ultra-low harmonic VSDs also improves power network reliability and efficiency.  variable speed drives (VSDs) There’s the added benefit that the facility can save on the capital costs of the equipment and space VSDs also play a pivotal role in expanding the design capabilities of HVACR. One key advantage is their ability to over-speed fans within the system to cover higher loads than the system was designed for. This flexibility allows them to operate in extreme conditions and still meet the needs of the facility, without installing significantly oversized systems to cover these rare peak loads. There’s the added benefit that the facility can save on the capital costs of the equipment and space where it is installed.  The challenge of harmonic distortion While newer healthcare facilities may already be equipped with HVACR systems controlled by VSDs, older facilities may require significant upgrades. Some VSDs can introduce unwanted electrical disturbances to the facility network, called harmonics, which affect the performance of electrical equipment and lead to higher energy losses. Harmonics increase line current, meaning that when fitting VSDs, power cables, and other components might need to be re-sized to be able to accommodate it. Filtering and control mechanisms Advanced ultra-low harmonic VSDs are designed to mitigate the impact of harmonics on electrical systems To address this issue, advanced ultra-low harmonic VSDs are designed to mitigate the impact of harmonics on electrical systems. Ultra-low harmonic VSDs incorporate sophisticated filtering and control mechanisms to reduce harmonic distortion, ensuring the reliability and efficiency of electrical infrastructure within healthcare facilities, including medical equipment used to treat patients. They also mitigate the need for a larger refit and higher maintenance costs, while ensuring compliance with regulatory standards governing harmonics and electrical quality.  Understanding the crucial role of air quality  Maintaining high air quality standards within hospitals is essential to minimize the risk of healthcare-associated infections (HAIs) and ensure the safety of both patients and medical staff. Poor air quality can lead to higher concentrations of bacteria, viruses, and fungi in the air, significantly increasing the risk of HAIs. These infections can lead to prolonged hospital stays, compromising patient safety, and further increasing healthcare costs for patients and providers. This is exactly what the COVID-19 pandemic highlighted. Regulatory standards and guidelines Only advanced ventilation systems controlled by VSDs can fully deliver what’s required Given these significant risks associated with poor air quality, healthcare facilities are subject to stringent regulatory standards and guidelines governing indoor air quality. Compliance with these standards is essential, and only advanced ventilation systems controlled by VSDs can fully deliver what’s required.  Breathing easier In conclusion, advanced HVACR systems controlled by ultra-low harmonic VSDs are essential for healthcare facilities seeking to improve air quality and provide a healthier environment for patients and staff. They also enhance energy efficiency and optimize associated costs, while ensuring compliance with regulatory standards. Adopting these advanced drives offers improved medical equipment reliability, as they take care of power quality and minimize electrical disturbances in the facility's power network. Ultimately that leads to better patient outcomes and hospital operational efficiency.

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.

It takes a proliferation of data centers to serve the growing computing needs of the Internet, and all those servers churning away create plenty of heat. Might some of that heat be harnessed and used for residential or commercial heating? The emergence of district heating systems, which provide thermal energy to multiple buildings from a single source, demonstrates the approach has broad possibilities. Air-cooled chillers and air-handling units used to cool data centers are like the technologies that cool residences and businesses. They just operate on a larger scale and require a higher degree of resilience and redundancy to ensure data center servers operate without interruption. District heating system The law of physics dictates that the energy you put into a data server will come out as heat, and heat is a byproduct of data center cooling systems. Rather than exhaust that heat into the outside environment, how can it be captured and channeled into a district heating system to heat water and/or to provide warmth to homes and businesses in the same neighborhood as the data center? Law of physics dictates that the energy you put into a data server will come out as heat  Mitsubishi Electric designs engineered solutions that both cool data centers and generate heat output that can be captured for district heating applications. “We want to capture the heat and repurpose it for someone else to use,” says Simon Prichard, Product Strategy Manager for Engineered Solutions for Mitsubishi Electric. Reusing wasted heat from data centers can help to decarbonize heating. United Kingdom's Energy Act 2023 An additional heat pump can be used to increase the “low-grade heat” generated by a data center to the temperature needed for district heating. Alternatively, district heating systems might be upgraded to accommodate the lower-temperature heat from data centers. Additional heat pump can be used to increase the “low-grade heat” generated by a data center. The United Kingdom and other governments globally are promoting the creation of district heating networks. Legislation such as the United Kingdom's Energy Act 2023 identifies areas within England where certain new and existing buildings will be required to connect into district heating networks. Legislation is pushing developers toward district heating and away from the use of fossil fuels. District heating applications Water cooling is a developing technology for data centers, which mostly use air-cooling systems In November 2023, the UK government awarded £36 million to a district heating system in West London that will share data center waste heat with up to 10,000 new homes. Hot air from a data center can provide some of the energy needed for a district heating system, and water-cooling systems can provide even more. Water cooling is a developing technology for data centers, which mostly use air cooling systems. Cooperation is needed to realize the scenario of capturing the heat from data centers for district heating applications. Government legislation can drive requirements to embrace the approach, but the multiple involved parties, including data center operators and the architects and engineers creating nearby communities, must also cooperate. Greater ESG goals Energy must be reused in the geographic area immediately surrounding the data center for the scenario to be financially viable. In an industrial estate, for example, the excess heat could be used for nearby farming; the reuse is not restricted to domestic or residential applications. The various parties tend to be “siloed,” so a concerted effort of “joined-up thinking” is needed to bring all the parties to the table to enable such a system. Construction of new data centers is accelerating, and the centers are getting larger. Construction of new data centers is accelerating, and the centers are getting larger. Currently, 4 or 5% of total electricity output is used by data centers, and ways to reuse that energy are a growing priority for ethical companies in the data center market. Large companies that use data centers are drawn to the district heating scenario to achieve greater ESG (Environmental, Social, and Governance) goals. Moving forward, it behooves everyone to think of data centers as not just generating data but as energy centers generating sustainable energy. Mitsubishi Electric’s products MEWALL mixes high version with energy efficiency, space optimization, and cost-effectiveness “We live in a connected world, and we need data centers,” says Prichard. “The world won’t work without them, but many people don’t know what a data center is and how much we rely on them. Society doesn’t realize how embedded they are.” Among Mitsubishi Electric’s products for the data center market is the MEWALL air handling unit, a “wall” of fans with built-in controls, valves, and filters that are mounted alongside a suite of data servers. MEWALL combines high performance with energy efficiency, space optimization, and cost-effectiveness. Water circulates inside the fans, using cold water produced by a chiller. View of the MEWALL system Smaller data center needs can be addressed using technology such as Mitsubishi Electric’s indoor s-MEXT high-precision air conditioner connected to a Mr. Slim R32 Power Inverter outdoor unit. The indoor unit is customized to the client’s requirements for use in a data center.  At the Data Center World trade show in London in March, Mitsubishi Electric used virtual reality (VR) to provide attendees with a simulated view of the MEWALL system. Given the dimensions of 4 by 2.3 meters, transporting the system to the show presented prohibitive cost and logistical challenges.

Recently, nine states pledged to accelerate the transition to clean buildings in their states, including a goal of deploying heat pumps to make up 65% of residential heating, cooling, and water heating by 2030. California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island signed a memorandum of understanding in February outlining their collective efforts to accelerate the deployment of clean technologies such as heat pumps in new and existing homes.  Benefits of heat pumps Fifteen percent of the world’s greenhouse gas emissions come from the heating and cooling of buildings and homes, and accelerating the use of heat pumps advances the goal of a cleaner, healthier environment.   “The door is closing on reasons to shy away from heat pumps because the technology is here, and the incentives and support from government programs are on the rise,” says Katie Davis, VP of Engineering and Technology at Trane Residential. “There is no better time than now to make the change for a more sustainable future.”  portfolio of residential heat pumps The new portfolio yields an emissions reduction of over 35% (compared to 2019), and the new 15 SEER heat pump Beginning this month, Trane Residential launches its new portfolio of residential heat pumps that achieve new levels of emissions reduction. The new portfolio yields an emissions reduction of over 35% (compared to 2019), and the new 15 SEER heat pump will meet Energy Star requirements.   “We saw the change in refrigerant regulation as an opportunity to propel us forward in technology toward a better environment,” says Davis.   Heat pump technology Heat pump technology has been around since the mid-1800s, and it has evolved significantly since that time. Within the last 10 years, improvements have been made in efficiency, in both the heating and cooling cycles. The use of vapor injection technology in the heating cycle has greatly improved the capacity and efficiency of heating with heat pumps.   Comfort mode Comfort mode provides a level of comfort similar to that of fossil fuel-burning furnaces Trane heat pumps also can deliver very warm air at the register through Comfort mode, which provides a level of comfort similar to that of fossil fuel-burning furnaces, says Davis. Homeowners who prefer furnaces due to the temperature of the discharge air have similar capabilities with Trane heat pumps.  Sustainability and efficiency Trane Technologies seeks to challenge what’s possible for a sustainable world, says Davis. “Sustainability is the foundation of how we design our products for the future of HVAC,” she says. Improvements in the efficiency of Trane Heat Pumps have a direct correlation to reduced emissions, which translates to energy savings on a homeowner’s utility bill.   Trane Link systems Other factors that assist in driving the transition to the electrification of heating are utility rebates The Trane Link systems provide up to an additional 5% energy savings to the homeowner using smart technology that efficiently manages the home load environment. Other factors that assist in driving the transition to the electrification of heating are utility rebates and a program that assists homeowners in making the shift.  Of course, "indirect emissions" and the greening of the grid have an impact on emissions as the industry moves toward the use of heat pumps and away from fossil fuel-burning systems. emissions reduction by design Trane is achieving industry-pioneering emissions reduction by design, and as the grid becomes greener, it will accelerate the impact the Trane portfolio will have on the industry and the environment, says Davis.  “At Trane, we utilize a multi-variable approach to reducing emissions in our product portfolio,” says Davis. “While a greener grid can help to accelerate the reduction in emissions, our systems utilize smart technology, lower global warming potential refrigerants, and improved efficiency in heating design to achieve industry-pioneering emissions reduction for our systems.”  alternative energy sources When designing for sustainability, several levers can be pulled to yield the best results Heat pumps play a role in encouraging more efficient energy sources. HVAC accounts for over 40% of the energy usage in a home. There is an opportunity for the development of capabilities in alternative energy sources for heating and cooling as well as improved energy management for the home. When designing for sustainability, several levers can be pulled to yield the best results. One of those levers is related to digital controls and smart systems.  Trane Link Variable Speed Trane Link Variable Speed Systems provide over 700 speeds to provide a pinpoint match to a homeowner’s load demand in a home. The system provides temperature control within 0.5 degrees F, humidity control to the exact setpoint defined by the homeowner, and provides up to 5% energy savings on utility bills.   By utilizing the digital technology within the control system, the heat pump manages comfort as well as efficiency to provide the best for the homeowner and the environment. For dealers, Trane provides Dealer Diagnostics that give precise information on runtime and system performance, in real time, to ensure the most optimal operating parameters for the best system performance and efficiency.  heat pump heating capability Two obstacles are cost and the customer perception of heat pump heating capability Two obstacles remain in the transition journey. They are cost and the customer perception of heat pump heating capability. “As we accelerate this transition, the time is now for utilities and government programs to step up and assist homeowners in electrification of heating,” says Davis. Inflation Reduction Act (IRA) funding is a step toward this assistance, but more is needed across the industry to ensure a rapid transition to cleaner equipment.   Consumer concerns In addition to cost, homeowners have not been properly educated on the advancement of heat pump technology over the last decade, and heating with heat pumps has improved significantly.  “The cost to convert from furnaces to heat pumps can be prohibitive, but with government incentives, like the IRA rebates, this becomes less of an issue,” says Davis. “Other concerns from consumers are energy bills and the concern that energy costs will rise with the use of heat pumps. While it is true that electric energy bills may rise, homeowners should see a reduced cost of use of other energy sources,” says Davis. “In the end, we move closer to parity.” 

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.”

Kepier School's phased transition to low-carbon CIAT heating technologies has delivered generous energy savings within a year of installation. CIAT worked with partners to initiate the school’s journey to net zero in 2022, returning to measure performance and optimize the system. CIAT is a part of Carrier Global Corporation, a global pioneer in intelligent climate and energy solutions. New high-efficiency heat emitters CIAT worked with BREng Hull Ltd, AA Projects, Quora Group, and Cool Designs Ltd to create a phased decarbonization plan for Kepier School in Northeast England, aided by the Condition Improvement Fund (CIF). Recognizing the challenges faced by many schools, Oliver Sanders, Carrier Commercial HVAC Director, United Kingdom, and Ireland, said, "For schools with new gas boilers aiming to reach net zero, it's most cost-effective to integrate them into a modernized heating infrastructure, ready for the next transition phase to heat pumps when the boilers reach end-of-life." Project featured a heating audit The project involved a heating audit identifying the need for new high-efficiency heat emitters The project involved a heating audit identifying the need for new high-efficiency heat emitters. Conventional radiators were replaced with seven surface-mounted high-level CIAT MajorLine and 31 CIAT COADIS fan coil units (FCUs). The seven gas boilers installed in 2019 were integrated into the new system's infrastructure, enabling them to be replaced as required to improve system efficiency and cost savings. Sizeable energy savings A subsequent review revealed sizeable energy savings. Gas usage was compared before and after the pandemic to avoid skewed data due to COVID-19 school closures. Findings revealed an 8.6% reduction of 2,824 m3 (~31,446.41 kWhr) from March 2022 to March 2023 compared to the period from March 2019 to March 2020. This achievement reduced the school’s carbon footprint and resulted in an 8% annual cost saving of ~£800 (average based on gas price fluctuations between March 2019-2020 and March 2022-2023). CIAT project partners BREng Hull  CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains Following commission, CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains.  "The process doesn’t stop once a solution has been designed, installed, and commissioned," said Rob Smelt, Managing Director of BREng Hull, adding "Experience shows that there are often significant additional gains to be made by optimizing the system in light of its real-world operation." The inspection revealed that some areas were imbalanced while others operated at sub-optimal temperatures. These issues were addressed to improve occupant comfort and reduce energy use and running costs. Carrier’s 2030 ESG Goal "The comfort level has improved significantly," said Brian Dixon, Kepier School Estates Manager, adding "We already gained control over specific rooms and areas, as opposed to the old ‘on or off’ heating system, and the latest work seems to have improved things even more. Future phases in our decarbonization plan will yield even greater energy and cost savings for the school." BREng Hull worked closely with equipment supplier Cool Designs Ltd during the scoping and specification stages, supported by CIAT application specialists. Projects like these contribute to Carrier’s 2030 Environmental, Social and Governance (ESG) Goal of reducing its customers’ carbon footprint by more than one gigaton.

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.
