Daikin, a global pioneer in heating and cooling solutions, has secured support from over 100 businesses and individuals in the Heating, Cooling, and Ventilation industry, for its open letter pressing political pioneers and candidates to establish clear policies on domestic low-carbon heating, provide incentives for adopting these solutions, and increase investment in related training programs. Alongside the open letter, Daikin introduced its own manifesto urging political parties to assist the UK in achieving its legally binding 2050 net zero climate target. This initiative coincides with Daikin’s recent research involving 2,000 British adults, which underscores significant public dissatisfaction with political inaction on environmental issues. Key Findings from Daikin’s Research Public Frustration with Political Inaction: 66% of respondents feel politicians are failing future generations by neglecting green issues. Demand for Government Solutions: 78% believe the Government isn’t doing enough to introduce energy-efficient solutions like heat pumps. Moreover, 76% of Brits want to make their homes more energy-efficient but are deterred by high material costs (57%), expensive installation (42%), and insufficient government subsidies (28%). Barriers to Greener Homes: 86% of participants urge the government to do more to promote home insulation and low-carbon heating systems. Scepticism About Net Zero Goals: Although climate change ranks third in national priorities, only 23% believe the UK will meet its 2050 net zero target, and 78% feel the government isn’t promoting energy-efficient solutions adequately. Innovative heating and cooling solutions Daikin is further urging the next UK Government to implement real action on climate change Daikin’s steadfast commitment to sustainability and innovative heating and cooling solutions positions it as a crucial advocate in the conversation about the UK's environmental future. With backing from over 100 businesses and individuals, Daikin is further urging the next UK Government to implement real action on climate change. National Residential Business Manager of Daikin, Simon Chapman, says: "By not taking immediate, robust action to support households with the transition to low-carbon heating solutions, we are missing a critical opportunity to significantly reduce the UK’s carbon footprint by a substantial 14%. Any lack of decisive action will put the UK’s commitment to achieve net zero by 2050 at serious risk." Several measures of Daikin To address these challenges, Daikin recommends several measures: Ensuring all new homes built annually are zero-carbon by 2025. Supporting and incentivizing landlords and homeowners to improve energy efficiency, thereby reducing heating costs and environmental impact. Providing stronger financial support for low-carbon heating solutions like heat pumps. Simon Chapman adds: "These steps are crucial for creating a sustainable future and making meaningful progress toward our climate goals."  Daikin would urge individuals and businesses to show their support for a cleaner and greener future, and to sign the open letter.

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.

By now, most of the HVACR industry is familiar with the HFC phasedown portion of the U.S. EPA American Innovation and Manufacturing (AIM) Act that was signed in 2020 and finalized in 2021. The first phasedowns started Jan. 1, 2020, with a 10% reduction in HFC refrigerant production, importation, and consumption, and was followed by an additional 30% reduction that began Jan. 1, 2024. As these regulations work to achieve a total 85% HFC phasedown from historic baseline levels by 2036, Technology transition rules will start to impact the industry as early as Jan. 1, 2025. Technology Transitions Often referred to as “sector controls,” Technology Transitions are the second of three main sections of the AIM Act. They focus on limiting the use of HFC refrigerants and supporting A2L adoption by calling for global warming potential (GWP) limits for refrigerants based on specific applications, including refrigeration, air conditioning, heat pumps, and more.  three new-generation refrigerants Three new-generation refrigerants help create a clear path to making refrigerant transitions that comply with the rules Although the Technology Transitions program is rather complex (providing rules for which refrigerants or GWP limits apply for which applications and when) focusing on just three new-generation refrigerants helps create a clear path to making refrigerant transitions that comply with the rules and support more sustainable operations. While several new refrigerants have been developed recently, many of the HVACR industry’s applications and equipment can be covered by focusing on these three refrigerants: R-454A, R-454B, and R-454C.   R-454A (AR4 GWP = 239)   Developed to replace legacy refrigerants such as R-404A, R-454A is an HFO blend offering zero ozone depletion potential (ODP) and a GWP of 239, lower than R-404A’s GWP of 3,920. R-454A is classified as a mildly flammable, low-toxicity A2L, suitable for low- and medium-temperature commercial refrigeration applications. The AIM Act Technology Transitions set a maximum GWP of 300 for several types of systems with charge limits up to 200 lbs., such as remote condensing units for food retail walk-ins and cascade systems. These systems are ideal for R-454A, given the refrigerant’s improved performance and reduced GWP compared with R-404A.  R-454B (AR4 GWP = 467)  Regarding refrigerants of the future at work today, R-454B is likely the one you’ve heard the most about. Establishing itself as the predominant replacement for R-410A in new air conditioners and chillers, R-454B started being used earlier this year. R-454B will be used in most equipment manufactured after Dec. 31, 2024. Offering a GWP of 467 compared with R-410A’s GWP of 2,088 (a 78% reduction), R-454B has been selected by most air conditioning and heat pump manufacturers worldwide.   R-454C (AR4 GWP = 148)  R-454C, with a GWP of 148, offers compliance with AIM Act regulations and is suitable for new systems R-454C, with a GWP of 148, offers compliance with AIM Act regulations and is suitable for new systems in applications requiring a GWP of <150. Two examples are small standalone units and larger system architectures with a charge size of >200 lbs. being developed for supermarkets.   For Use in New Equipment Only  R-454A, R-454B, and R-454C are HFO-blend refrigerants and have slightly different R-32 and R-1234yf components percentages. All three are individually optimized for peak performance and carry an A2L mild flammability safety classification. As A2Ls, these refrigerants can only be used in new equipment designed to mitigate leaks and flammability risks and must be installed according to OEM instructions and in compliance with applicable safety standards and building codes.  Easy as A, B, C  In anticipation of AIM Act regulations and the continued adoption of R-454A, R-454B, and R-454C, the HVACR industry has ramped up A2L training and engineering support significantly over the past few years. So, while sorting through the regulatory changes and becoming familiar with the new refrigerant options may seem complex, focusing on these three A2Ls will hopefully make your refrigeration transition, and your business’s future growth as easy as A, B, C.  

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.

The flammability of the new class of low-GWP refrigerants is a source of misunderstanding and unnecessary anxiety among contractors who will be working with the newer materials, which must be used by HVAC equipment manufactured beginning Jan. 1, 2025.   A2L refrigerants The newer A2L refrigerants, specifically R-454B, perform similarly to previously used materials such as R-410A, and flammability is so mild as to be almost negligible. What’s needed is more education to make contractors more comfortable with the newer refrigerants. And sensible precautions, of course.   flammability of refrigerants Among the trainers educating the industry on the benefits of, and needed precautions for, the new materials is Don Gillis, Technical Trainer of Chemours.   “The flammability part of it is the elephant in the room,” says Gillis. “Our training seeks to remove the fear of the unknown and to get ahead of what the expectations are.”  Don Gillis experience At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition Gillis’s background includes more than 32 years of experience in the industry, 24 of which were on a service truck. Before coming to Chemours, he was the Senior Technical Trainer for Copeland compressors where he helped to train thousands of contractors across North America.  At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition in hundreds of training sessions this year.   peculiarities and similarities of new refrigerants “Change is now coming so fast that technicians are struggling to keep up,” says Gillis. “We need more education, not just about the differences in the new refrigerants but also about the similarities. We need to understand the peculiarities and the similarities of new refrigerants compared to what we used in the past.”   Features of A2L refrigerants The refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world Working with A2L refrigerants such as Opteon XL41 (R-454B) is similar to working with R-410A. For R-454B systems, the installation and service procedures are similar. Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions.  When working with R-454B, processes that were once described as good practice will be required. These processes include purging a line with nitrogen to remove any residual refrigerant, testing lines under pressure for 60 minutes, and documenting the results.  training sessions Gillis is seeing higher-than-expected attendance at his training sessions this year, with actual attendance sometimes doubling what was expected. There are classes with more than 100 in attendance, even 200 and 300 in some cases. While most of the training is geared toward contractors, distributor training is similar, ensuring that the “counter people” speak the same language as their customers when it comes to the transition.   Urgency due to transition “We are not having an issue of people not coming to training,” says Gillis.  “I think right now there is a new urgency because [the transition] is happening. Dealers and distributors are telling them the new equipment is coming out, and they are peeking in to see what the hubbub is all about. We want everyone to get better. The more knowledge the better.”   R-454B refrigerant availability All equipment manufactured or imported beginning in 2025 will use newer refrigerants New equipment that uses R-454B refrigerant will be on the market within weeks. At least three original equipment manufacturers (OEMs) say they will have equipment out by the end of the first quarter. All equipment manufactured or imported beginning in 2025 will use newer refrigerants.  Misinformation Misinformation is a problem as the refrigerant transition looms, says Gillis. For example, 50 to 60% of attendees at a recent training session were still under the impression that the new refrigerants contain hydrocarbons such as propane. Not true. The flammability of A2L refrigerants more closely resembles the refrigerants currently in use than materials at the far end of the flammability spectrum.  Fact-checking and myth-busting A2L refrigerants have already been used safely for years in automobiles, window air conditioners, PTAC systems, and dehumidifiers.  “I’m all about fact-checking and myth-busting,” says Gillis. “You don’t know what you don’t know.” Some of the misunderstandings may have come from earlier messaging in the industry that addressed A2Ls along with other “flammable refrigerants” such as propane, thus confusing the matter.  Key points Key points Gillis seeks to communicate in his training sessions include:  ∙There are no hydrocarbons or propane in A2L refrigerants.  ∙Although similar to previous refrigerants, an A2L refrigerant cannot be used in an existing unit.   ∙No extra ventilation or placards are required for trucks carrying A2L refrigerants; tanks of Chemours’ Opteon XL41 (R-454B) refrigerant can be transported on their sides.   ∙The 440-pound maximum allowable refrigerant truck load stays in place.  ∙Safety and handling requirements and good installation and service practices are required.  ∙Factors such as servicing, installation, safety, pressure, temperatures, and oils are the same for R-454B as for R-410A.   To access educational resources, contractors and others may visit Opteon.com to request training by webinar, remotely, or in person. There are also YouTube videos available on demand.   training certificate Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with NATE, ACCA Although there is currently no EPA requirement for special training on the new refrigerants, the jury is out on whether a requirement might be forthcoming. There currently are also no federal or state certifications. Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with North American Technician Excellence (NATE), Air Conditioning Contractors of America (ACCA), or whomever.   high-GWP refrigerants The U.S. AIM Act will limit the amount of high-GWP refrigerants that can be made in coming years. As the manufacture of legacy refrigerants is phased out over time, existing legacy systems will need to use more reclaimed/recovered refrigerants from existing systems. Fortunately, the processes of reclamation are improving, and even refrigerant mixtures will still have value in the market moving forward. {##Poll1709537519 - What is your preferred format when it comes to training on new aspects of HVAC equipment and installation?##}

The idea of Energy as a Service involves shifting the traditional business model from selling energy as a commodity to providing a comprehensive package of goods and services to address a customer’s energy use and management. Rather than selling energy, the approach encompasses complete stewardship of a company’s energy needs in exchange for a monthly fee. Because 40% or so of a company’s typical energy needs are related to heating and cooling systems, implementing Energy as a Service (EaaS) is tied directly to a company’s HVAC systems. heat pumps and HVAC technologies In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount, say 5%, below what they currently pay. By then strategically seeking to lower the customer’s energy costs by more than 5%, the EaaS company uses the extra margin to pay its own costs and to attain a profit. For example, if a customer’s energy costs can be lowered by 30%, the EaaS company retains 25% every month for the term of the agreement, typically 10 years. Any costs associated with providing the service come out of the 25%. In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount Specifically, working to lower energy costs by that much involves an upfront investment in infrastructure, such as heat pumps and HVAC technologies, to lessen energy consumption. The idea is that the profitability of lowering energy costs will offset even a substantial investment over time. Energy-related infrastructure Briefly stated, that is the business model of Budderfly, which assumes management of a company’s energy infrastructure and becomes the “account holder” with the utility. Once an EaaS contract is signed, Budderfly then invests to upgrade the customer’s energy-related infrastructure, including LED lighting, refrigeration, etc., in addition to HVAC. The goal is to decrease energy usage by 30% or more.  Budderfly typically upgrades the variable frequency drive (VFD) When upgrading the infrastructure, Budderfly “owns” any new infrastructure assets for the term of the EaaS agreement, say 10 years, and amortizes the cost over the timespan. At the end of the term, the assets are turned back over to the customer unless they renew the contract. In the HVAC arena, Budderfly typically upgrades the variable frequency drive (VFD), economizers, and other equipment in a rooftop unit or other machinery when it takes on a new customer. Embraces the EaaS scenario EaaS has a direct incentive to invest in the newest technology to slip the client energy usage “Looking at the opportunity to save 5% of their energy costs, many customers think it seems too good to be true,” says Al Subbloie, President, CEO and Founder at Budderfly. The price of the EaaS contract is based on a two-year review of the customer’s utility bill, which creates a baseline against which the 5% discount is provided. On the consumption side, replacing a rooftop unit with a new Lennox, Carrier, or Trane high-efficiency unit can provide 30 to 40% savings in energy usage. When a customer embraces the EaaS scenario, the EaaS company has an immediate incentive to invest in the newest technology to lower the customer’s energy usage. The more they save on energy, the more they earn in profits. EaaS approach In contrast, in a business model involving energy purchased as a commodity, there is little urgency to upgrade the equipment. That explains why so much equipment currently installed is so out-of-date and energy inefficient, says Subbloie. “We did not expect the infrastructure to be so bad,” he says. “I am sharing something the world is not aware of. As long as cool and hot air are coming out of the vents, no one is looking at the energy impact.” In fact, the EaaS approach is a growing factor in decarbonization. “We are a private capital method to save the world,” says Subbloie. “We are aligning capitalism and putting it to use to save the world (from climate change),” he says. Additional investments by Budderfly Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs Subbloie says Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs. Of the 30%, Budderfly returns 5% typically to the customer and then spends about 15% on capital improvements, amortized over 10 years. Additional investments by Budderfly include 3 to 4% on technology such as thermostats, metering and controls, and data systems. Other costs are to pay Budderfly’s 300 or so employees.  In the refrigeration realm, which might account for 15 or 20% of energy usage, Budderfly deploys controllers (such as KE2 Therm Solutions and NRM) to smartly regulate the compressor operation in refrigeration units. Door alert monitors and upgraded seals avoid any leakage of cool air. Deploying R-290 (propane) refrigerant systems boosts energy efficiency. EaaS strategy When Budderfly deploys solar systems, the cost becomes just another line on the customer’s bill – there is no purchase agreement or lease involved. Budderfly is transparent with the customer in terms of the money they invest in infrastructure and other costs. In addition to providing the customer with the initial 5% discount, Budderfly also typically shares with the customer half of the proceeds of any energy savings they can achieve above 30%. The EaaS strategy is applicable to a variety of markets, but Budderfly is finding initial success in the quick-service restaurant (QSR) market, where repeatable footprints of individual locations make EaaS calculations predictable and scalable. Probably 80% of their business is in casual dining and QSR installations, including 75 or so well-known restaurant brands; they work with large franchisees who operate multiple brands. top-down relationships Budderfly also has firms in healthcare needs, nursing facilities, office buildings, amenity stores Budderfly is also working to establish “top-down” relationships at the restaurants’ corporate level, which has the ability to impose EaaS as a standard throughout its footprint. “As the climate focus becomes more important, a restaurant brand might say to do it everywhere,” says Subbloie. Hotels and motels are another vertical markets amenable to this approach, and Budderfly also has business in healthcare markets, nursing facilities, office buildings, convenience stores, and other retail. They seek to limit each building’s size to 200,000 square feet or less. Regulated and deregulated rates Budderfly has a team that handles the onboarding of new customers, which involves a short, two-page agreement. Their automated system is connected to 500 utilities, and Budderfly tracks all the regulated and deregulated rates. If rates go up, their billing increases, still based on the 5% reduction that is part of the agreement.  Budderfly benefits from its high-volume acquisition of HVAC equipment at lower prices. “We buy a lot of stuff, we have agreements to buy at volume pricing, and we are constantly negotiating to lower the price,” says Subbloie. “We buy the best of the best to achieve the greatest energy-saving outcome, for obvious reasons. We negotiate prices on the expectation that our volume will make it lucrative (for OEMs).” Subbloie says Budderfly is the largest buyer of roof-top units in the country. Energy-efficient HVAC systems Budderfly’s model enables the facility of the latest and most energy-efficient tools In the scenario of buying energy as a commodity, customers have less incentive to proactively replace their HVAC infrastructure with more efficient models. They also may not have the means to invest in capital improvements to achieve better energy efficiency outcomes. In contrast, Budderfly’s model encourages the installation of the latest and most energy-efficient equipment, and that the equipment is fine-tuned and maintained. By pushing the transition to decarbonization based on an old-fashioned business motive (i.e., profit), Budderfly seeks to jump-start the adoption of more energy-efficient HVAC systems on a large scale. “We have an economic model that is sustainable,” says Subbloie. Investment in AI Budderfly also provides customers with abundant data on their energy usage, including submetering architecture that does 20 to 40 measurements per location.  Each point of energy use reports back every five seconds, providing operational data and suggesting a possible investment in artificial intelligence (AI) to make operations even smarter. 

Sherborne School in Dorset has successfully improved the reliability and efficiency of the heating system serving its Big School Room (BSR) building with the installation of four new Remeha Gas 120 Ace boilers using a Remeha prefabricated cascade arrangement. Remeha is part of Baxi. Founded in its current guise in 1550, Sherborne School’s history of educating boys dates back to the 12th century. Given its rich history and reputation for excellence, creating the optimal warm and comfortable learning environment for its students and teachers is a key priority for the School’s estates team. However, refurbishing the heating system in Victorian school buildings like Big School Room can present challenges. Big School Room (BSR) building Until recently, the building had been relying on six increasingly inefficient and unreliable boilers for heating This two-floor building, which looks onto the Courts, was built in 1878 to provide a new assembly hall and classrooms for the School. Until recently, the building had been relying on six increasingly inefficient and unreliable boilers for heating. When they reached end of life, the estates team asked mechanical engineering services company - Cosgrove & Drew to evaluate the practical options to achieve a more modern, efficient and reliable heating system. Obstacles to refurbishing the heating system Neil Price, Senior Technical Manager at Cosgrove & Drew, said: “The fabric of the Victorian building and the operating temperatures of the heating system presented several obstacles.” Relocating the plant room to a repurposed room or designing an external packaged plant room were two options that had to be ruled out due to budget implications. Heat pumps also had to be disregarded as a viable option. Baxi’s site survey identified additional hurdles Neil invited Baxi to accompany him on a site survey to discuss the achievable solutions within the project parameters. The site survey identified additional hurdles. Access to the plant room was restricted due to its basement location, narrow walkways, stairwells and doorway. The low ceiling inside the plant room was a further complication. Cosgrove & Drew recommended installing new modular energy-efficient replacement boilers with a Plate Heat Exchanger as the most practical and reliable approach to meet the School’s requirements for a more energy-efficient heating service, minimal disruption and easy future maintenance. Baxi proposes installing four Remeha Gas 120 Ace boilers To overcome the space restrictions, Baxi proposed installing four Remeha Gas 120 Ace boilers To overcome the space restrictions, Baxi proposed installing four Remeha Gas 120 Ace boilers using a bespoke Remeha off-site fabricated cascade system complete with insulated pipework set and pumps and a specially sized Plate Heat Exchanger (PHE). Neil Price said: “I’ve used Remeha boilers before and have been impressed by their quality and reliability. So, it was a logical decision to use Remeha boilers on this project. Given the access limitations, the option to install them on a rig made this the obvious choice.” Baxi and Cosgrove & Drew partnership Working with Cosgrove & Drew, the Baxi team prepared CAD and 3D drawings of the boiler cascade arrangement bespoke to the design parameters and integrated specially sized pump sets and a plate heat exchanger (PHE) into the design. The PHE was recommended to separate the new boilers from the existing heating system and protect them from any debris, corrosion or poor water quality. In addition to the boilers, pumps and PHE, the rig design included a pressurization unit, a dosing pot and an expansion vessel. To overcome the limited access restrictions through a narrow doorway, the proposal was for the rig to be delivered in units. These would be bolted together inside the plant room and connected to the existing system. Once the design was agreed, production took place in a factory environment, with comprehensive end-of-line testing. Gas 120 Ace boilers are extremely compact Neil Price adds: “It’s proved a great solution. The Gas 120 Ace boilers are extremely compact, and the bespoke prefabricated rig design made it possible to achieve a space saving option that not only made access into the plant room easy but fits nicely into the available space for easier future maintenance.” Reduced installation time was an added advantage, as he explained: “A major benefit of using the bespoke designed prefabricated rig service that Baxi offers is the time savings it delivers.” Baxi’s engineers safety tested the installation “With no need to size all the individual components and no onsite welding required, on site time and labor was reduced significantly,” said Neil Price, adding “This also minimizes disruption which was particularly important as this project took place during term time. Commissioning was carried out by Baxi’s commissioning engineers who safety tested the installation.” Neil concluded: “The BSR plant room has been completely transformed on both a practical and aesthetic level. It's great!” A spokesperson from Sherborne School stated: “The installation project went smoothly, and the School is hopeful that the improved performance and reliability will result in reduced gas consumption.” Fully modulating Remeha Gas 120 Ace series The fully modulating Remeha Gas 120 Ace series is available in 65kW, 90kW and 115kW outputs with bespoke designed cascade options available for greater design flexibility. Extremely compact at only 600mm wide, the Gas 120 Ace range will fit into even the smallest of plant rooms. It is supplied with onboard time and temperature controls, with direct connection to a Building Management System provided as standard to maximize heating efficiency. Its quiet operation, high efficiencies and low Class 6 NOx levels make the Gas 120 Ace particularly suitable for use in schools.

Honeywell announced that Hisense, a global consumer electronics and appliance manufacturer, will incorporate Honeywell's energy-efficient Solstice low-global warming potential (GWP) refrigerant into its residential air conditioning units. Hisense units will use Honeywell Solstice® 454B, a low-GWP refrigerant acknowledged for its outstanding performance in both cooling and heating. Hisense’s decision to integrate Honeywell’s Solstice refrigerant is in line with global efforts to phase out higher GWP refrigerants for air conditioners and heat pumps. Technological advancements "Driven by a commitment to pioneering scientific and technological advancements, Hisense relentlessly strives to enhance the quality of life and bring boundless joy to countless families,” said Hao Wang, general manager of the Supply Chain Management Department at Hisense. “Our alliance with Honeywell signifies a formidable leap towards sustainability, as we integrate cutting-edge refrigerants into our industry-pioneering air conditioning units, ensuring unparalleled cooling efficacy with minimal environmental impact." Use of high-HFCs Integration of Honeywell’s Solstice refrigerant into Hisense units comes amidst the recent increase The integration of Honeywell’s Solstice refrigerant into Hisense units comes amidst the recent increase in legislative mandates across the country to reduce the use of high-GWP hydrofluorocarbons (HFCs) in response to the growing global emphasis on addressing climate change.  The partnership between Hisense and Honeywell also follows the U.S. Environmental Protection Agency’s recent announcement of a 40% quota cut in the production of HFC refrigerants as of January 1, 2024. Lower carbon footprints “The world is migrating away from refrigerants with high-global warming potential, but it is also accelerating innovation to create responsible replacements that lower carbon footprints and improve energy efficiency, all without sacrificing safety and end-product performance,” said Jeff Dormo, president of Honeywell Advanced Materials. “Honeywell anticipated the need for these solutions more than a decade ago when we introduced our Solstice technology, and today we are pleased to be able to partner with manufacturers like Hisense that are leveraging our expertise to enhance their own sustainability efforts in alignment with the global energy transition.” New capacity for its Solstice technology Honeywell has invested more than $1 billion in research, development and the creation of new capacity for its Solstice technology, which currently has applications in refrigerants, blowing agents, aerosols and solvents, and is also being evaluated for expanded use in metered dose inhalers. Since its introduction in 2011, the use of Honeywell Solstice technology has helped avoid the potential release of the equivalent of more than 326 million metric tons of carbon dioxide into the atmosphere or the carbon emissions from nearly 70 million gasoline-powered passenger vehicles per year.

Shadow Industrial, the UK’s pioneering shortwave infrared heating specialist, recently helped St. Helen’s Chapel, in Colchester, Essex, specify and install a low-carbon heating system, keeping the congregation warm and costs down. Installing 14 of its powerful ceiling-hung and wall-mounted heaters and 16 controllers from scratch, the new system has given visitors a warm, comfortable and sustainable place to worship, whatever the weather. Futureproofing sensitively Reducing energy consumption and increasing its efficiency is a goal that touches on every part of UK business and industry, especially against the backdrop of the drive towards Net Zero 2050. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide. With strict and ambitious ESG commitments, futureproofing these assets in the face of tighter climate change regulation, whilst delivering their core function is a real challenge. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide Some of its sites are centuries old, and it can be difficult to upgrade facilities here. One particular area of concern is how to heat these large, high-ceilinged, and poorly insulated structures. Crucially, visitors need to be comfortable, but simultaneously ensure utility bills and waste are kept to a bare minimum. Warming-up the congregation It was an issue at the forefront of the church’s mind when they took over the lease of St Helen’s Chapel, Colchester, Essex in September 2020; especially as the 16th Century, Grade-II building had no existing HVAC system. The congregation bore the brunt of this unfortunate situation over three consecutive winters, where temperatures would sometimes plummet down to 1°C. It made the church a particularly uncomfortable place to worship.  Grade-II building had no existing HVAC system Initial use of oil-fired heaters proved futile, failing to provide the necessary levels of warmth and releasing a large amount of CO2. Next, industrial fan heaters were introduced, to little effect; noisy, they also proved a significant disruption to services. Following further research, they decided to trial shortwave infrared heating, approaching Shadow Industrial on the recommendation of their electrician, who had installed its solutions on previous projects. A heating revelation Shortwave infrared heating is one of the fastest-growing and most disruptive categories of heating Shortwave infrared heating is one of the fastest-growing and disruptive categories in the heating and ventilation sector. Simply, the technology works by emitting focused radiant heat through a precision-engineered smooth parabola reflector; it heats the person, not the air around them. Wall-mounted and directed downward at individuals, the energy creates a comfortable and instant warmth, mimicking the gentle heat of the sun. It’s fast becoming popular in historic ecclesiastical buildings as it’s easy to install, with limited impact on the structural fabric, in addition to its effective heating function and low energy consumption. It is also unaffected by changes in air movement, making it particularly efficacious in drafty settings such as those found in heritage sites, like St. Helen’s Chapel.  Unrivalled performance, at a reasonable price Installed in 2023, Shadow Industrial’s systems have significantly improved the comfort of congregants, allowing them to remove coats during services. The impact was particularly felt among older people and children, for whom extreme cold can have an adverse impact on health during extended services. The client was worried their tight budget would not be enough to fully equip the church’s interiors Initially, the client was worried their tight budget would not be enough to fully equip the church’s interiors with heaters. However, it proved far cheaper than traditional electric or gas central heating. The entire system and installation totaled £20,000. Putting this in context, they were initially quoted £100,000 for underfloor heating; this represents a massive 80% upfront saving, with greater performance–a no-brainer decision. The entire system and installation totaled £20,000. Shadow Industrial and its team Commenting on the project, Shadow Industrial’s founder, Steve Levy, says, “We are deeply committed to the preservation and longevity of heritage buildings. With a focus on comfort, we have successfully executed numerous heating projects with this in mind, of which St. Helen’s Chapel is the latest. It’s such an important local landmark and it was great to be able to provide a solution that benefits all those who work, volunteer, and pray here.” Father Mark Shillaker added, “Shadow Industrial’s infrared heating systems have had a transformative effect. Now visitors can worship in maximum comfort even on the chilliest winter mornings. In fact, since we’ve installed these heaters we’ve actually seen an uptick in service attendance. Many thanks to Shadow Industrial and its team for their expertise and ongoing support.” Church of England's Heat Decarbonization Plan Shadow Industrial’s electric heating systems, present a low-carbon, net-zero alternative ideal for heritage structures, churches, and culturally significant buildings. They even align with The Church of England's Heat Decarbonization Plan, offering compliance and sustainability in a non-intrusive way.

Demeva Refrigeration Limited has installed a high-efficiency, state-of-the-art BITZER ammonia refrigeration system at Pilgrim UK's meat processing facility at Bromborough, Wirral, dramatically reducing the company’s energy costs and carbon emissions. Energy costs for the previous cooling system were £146,000 a year, compared with an estimated £61,000 for the new BITZER ACP pack, saving over £80,000 a year in running costs–a reduction of nearly 60%– and delivering substantial savings in carbon emissions. The project is part of a site-wide energy efficiency program designed to reduce power consumption and carbon emissions. New BITZER ACP system Timing on the project was critical due to the need to ensure continuity of cooling at the production facility Demeva Refrigeration Limited, based in Formby, Merseyside, specified a 707 kW BITZER Ammonia Compressor Pack (ACP), powered by high-performance screw compressors, to replace an end-of-life ammonia system by another manufacturer that had been in service for 20 years. The existing ammonia charge was retained for use in the new system, further supporting the economic case for the upgrade. The new BITZER ACP system provides primary cooling at an evaporating temperature of −9°C for the site's secondary glycol circuit, serving cold stores at 2°C and air handling units at 8°C within the processing facility. Timing on the project was critical due to the need to ensure continuity of cooling at the production facility. This was assisted by being able to run the system’s second compressor during the switchover. Straightforward modifications A logistical challenge was removing the old system and locating the new pack in position in the plant room. This required relatively straightforward modifications to pipework to connect the ACP pack to the central glycol system, followed by an electrical connection. "It was the first BITZER ACP pack we have installed," said Dean Rawling, Demeva Director. "Having assessed the technology currently available on the market, we believe BITZER's ACP system is the most efficient ammonia refrigeration solution available. Plus, importantly, it has the added safety benefit of being built and tested in pristine factory conditions by BITZER." BITZER's manufacturing and R&D facility BITZER's factory systems and technical support are second to none, and it gave the customer confidence" In the run-up to the replacement, the project leads from Demeva and Pilgrim UK visited BITZER's manufacturing and R&D facility in Stuttgart, Germany, to see first-hand the production process. Dean Rawling: "BITZER's factory systems and technical support are second to none, and it gave the customer confidence that the proposed ammonia solution was designed, built and tested in a world-class facility by people with deep experience of the technology and its application." Support from BITZER A key target for the project was to achieve payback on investment within one to one-and-a-half years. This was achieved as a result of the significant energy savings. Once the pack was installed, BITZER engineers from Germany attended the site to assist with commissioning and ensure the plant was optimized to deliver the anticipated savings. Adrian Spencer, Demeva's Refrigeration Manager, said: "The support from BITZER throughout the project was first class, from first contact to final handover. BITZER UK's James Graham was a key point of contact and provided excellent support throughout." Building Energy Management System Other energy-saving measures implemented at the site include the replacement of the evaporative condenser for the refrigeration pack, the installation of modern high-efficiency glycol pumps on the secondary circuit, and a new Building Energy Management System to provide site-wide monitoring. Other energy-saving measures executed at the site hold the aid of the evaporative condenser Neil George, Pilgrim UK’s Engineering Manager, said: "Responsible energy use is a major area of focus for our business. We are constantly looking for opportunities to improve energy efficiency and reduce emissions. The BITZER ACP pack, combined with the other efficiency measures implemented by Demeva Refrigeration, will significantly reduce power consumption at Bromborough and deliver significant savings in carbon emissions." Reduce carbon emissions The project is part of a multi-million-pound investment program by Pilgrim UK to further enhance the sustainability of its operations, with the aim of achieving net zero by 2030. Alongside upgrades to the refrigeration plant, this includes replacing gas boilers with heat pumps and completing the transition to LED lighting across its sites. The company already has local solar and wind projects at many locations and is expanding these to the remainder of its manufacturing plants across the country, helping to reduce carbon emissions by an estimated 11,000 tonnes a year. Zero GWP refrigerant BITZER's ACP range has been designed to meet the requirement for very high-efficiency cooling for industrial applications with a zero Global Warming Potential (GWP) refrigerant.  In addition to its exceptional part-load efficiency, it offers outstanding resilience, with a back-up compressor in the unlikely event of a failure, and rapid commissioning due to its plug-and-play design. Author's quote BITZER can build ACP units in a high-quality factory environment, ensuring the highest possible system" Kevin Glass, Managing Director of BITZER UK, said: “Ammonia refrigeration systems have traditionally been built as one-offs, often in less than ideal conditions. BITZER is able to build ACP units in a high-quality factory environment, ensuring the highest possible system integrity, absolutely essential when working with ammonia.” He added: “The modular design means that contractors can quickly connect up ACP units on site with a few simple pipework and electrical connections. This dramatically speeds up with process of installation and commissioning.” BITZER screw compressors ACP packs are based on compact BITZER screw compressors, which result in a smaller footprint than equivalent-capacity reciprocating compressors. In addition to the inherent efficiency of screw compressors, the speed of the lead compressor is controlled by an integrated Variable Speed Drive (VSD), which significantly increases part-load efficiency and enables soft-start, important on sites where power headroom is limited. A further benefit for end users is that the screw compressors used on ACP have much longer maintenance intervals than reciprocating compressors, further reducing the cost of ownership over the plant's lifetime.

When a company is one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc.
