It’s an exciting and challenging time to be an HVACR professional. The industry is rapidly evolving to implement advanced technology and adapt to environmentally conscious regulations all while experiencing a skilled labor shortage. As contractors struggle to keep up, many are turning to HVACR press fittings for their efficiency, safety, and reliability. The demand for these press fittings has nearly doubled in the past five years alone.  unique characteristics While the global shift to press continues to gain traction, the drivers and patterns for their adoption differ based on the unique characteristics and regulations of each region. Let’s explore how contractors around the world are implementing press to maximize their businesses.   United States & Canada  The key factors driving this trend are the speed and consistency of installation, which results in reduced labor In the U.S., press fittings are primarily used for larger-scale projects, including VRF applications, commercial buildings, institutions, and multi-family homes. However, residential contractors are also starting to adopt the press. The key factors driving this trend are the speed and consistency of installation, which results in reduced labor and material costs, allowing contractors to complete more jobs in less time. This is especially crucial in a country experiencing a severe shortage of skilled labor, as novice technicians can learn to install press fittings in a single training session.   Adoption of press fittings In Canada, the adoption of press fittings is also focused on large-scale commercial projects. However, another major driver for using press fittings in Canada is the flameless installation aspect, which is particularly useful for projects in sensitive environments like healthcare facilities, government buildings, and occupied structures. Unlike the U.S., where press fittings are widely accepted, only one press fitting manufacturer is approved in Canada: Rapid Locking System (RLS). This is because Canada’s HVAC industry is heavily regulated by the Technical Standards and Safety Authority (TSSA), whose regulations are stringent and many other press manufacturers have not been approved for use in the country.   Press adoption The U.S. has seen the highest rate of press adoption on its east coast, primarily the New England region While contractors in both the United States and Canada seem to have similar motives for converting to the press, the countries are seeing the most growth on opposite coasts. The U.S. has seen the highest rate of press adoption on its east coast, primarily the New England region, where commercial development is booming. Although Canadian contractors have been slower to adopt press, many are based in the western providence of British Columbia where large metro areas such as Vancouver experience higher building values and the speed of completing projects is consequential.    Latin America  Contractors in Latin America are increasingly adopting press fittings due to their straightforward implementation and reduced training requirements. The lack of formal trade schools in the region makes quick, easy-to-replicate training critical for contractors. Labor is often inexpensive but with minimal training, press fittings offer a reliable alternative to brazing, providing consistent results without requiring advanced skills. This is particularly appealing in a market where investing in contractor education is more expensive than simply employing them to do the job.  High call-back percentage Press fittings address this issue by virtually eliminating the chance of human error, leading to fewer reworks The high call-back percentage in Latin America— which sits around 90% is largely due to untrained and inexperienced contractors installing HVAC/R equipment incorrectly. Press fittings address this issue by virtually eliminating the chance of human error, leading to fewer reworks and greater overall efficiency. For larger projects such as VRF systems, commercial buildings, and government contracts, the consistency and reliability of press fittings are crucial. Contractors working on these projects need tools and processes that ensure the work is done right the first time.  On-site efficiencies The implementation of press in Latin America has not only improved the quality of installations but also enhanced on-site efficiencies. With press fittings, the need for extensive brazing and complex procedures is minimized, allowing contractors to complete jobs with fewer people and in significantly less time.  Use of specialized tools and jaws The use of specialized tools and jaws ensures consistent connections across different contractors, reducing errors The use of specialized tools and jaws ensures consistent connections across different contractors, reducing errors and providing peace of mind in a market where rework can be costly and time-consuming. This approach enables contractors to deliver reliable results while maintaining a price-conscious mindset, ultimately driving profitability and customer satisfaction.  Australia  Australian HVAC contractors are very proud of their brazing craftmanship, and for good reason. Still, the adoption of press fittings is gaining traction, primarily for its health and safety benefits. Press fittings eliminate the need for open flames, significantly reducing fire hazards, which is especially crucial in a country prone to wildfires. This feature not only helps prevent accidental ignitions but also makes working conditions safer during the scorching Australian summers when temperatures soar and the risk of heat stroke increases. Press fittings advantages The ability to bypass the need for hot work permits, which can streamline the installation process Additionally, using press fittings allows contractors to avoid lugging heavy brazing equipment to job sites, offering a more convenient and efficient workflow.  Another advantage of press fittings in Australia is the ability to bypass the need for hot work permits, which can streamline the installation process and save contractors significant time. This is because press fittings don't require open flames or additional fire safety precautions like fire spotters and fire safety equipment. Reducing costs By eliminating these requirements, contractors can reduce costs and quickly complete more projects. While press fittings will never entirely replace brazing, they serve as a practical alternative for projects where safety and efficiency are paramount, offering contractors a more adaptable solution for their installation needs.  Addressing labor shortages Despite the varying reasons for embracing press fittings, the common thread across all regions is the emphasis on efficiency, safety, and the need to address labor shortages. As the HVACR industry continues to evolve, press fittings are poised to become an increasingly indispensable tool, empowering contractors to deliver reliable and cost-effective installations while meeting the demands of a dynamic global market.

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.

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.

Revised building codes, based on model “I-Codes” developed by the International Code Council (ICC), are being widely adopted to allow A2L refrigerants to be used in comfort air conditioning applications. Previously, the use of A2L refrigerants, which are “mildly flammable,” was not allowed by building codes in force in 2021 and before because of safety concerns.   benefits of A2Ls However, the benefits of using A2Ls instead of refrigerants with higher global warming potential (GWP) have led to their acceptance as a replacement for hydrofluorocarbons (HFCs) in air conditioning applications. In response to the greater acceptance, driven by EPA refrigerant cutbacks, ICC has revised their building codes to permit the use of A2Ls, and local jurisdictions are in the process of adopting the revised building codes.  2024 I-Code changes Approved code changes in the 2024 IBC, IFC, and IMC allow commercial and residential use of A2L refrigerants The 2024 I-Code changes facilitate compliance with new refrigerant requirements and support producers and refrigerant appliance manufacturers already transitioning to lower-GWP solutions such as A2Ls.  Approved code changes in the 2024 International Building Code (IBC), International Fire Code (IFC), and International Mechanical Code (IMC) allow commercial and residential use of A2L refrigerants to replace refrigerants. The use of A2L impacts all three intertwined sets of building codes, which have been undergoing the three-year amendment process since 2021.  model codes and standards The International Code Council is a global source of model codes and standards and building safety solutions that include product evaluation, accreditation, technology, training, and certification.  ICC is working with the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) to partner with the construction industry and to facilitate legislation to navigate this positive change.  The IBC, IMC, and IFC code revisions, all managed by ICC, have been approved; two finalized codes were published earlier in 2023 and the third is being released in November 2023. Building, mechanical, and Fire codes Building code revisions align with established safety standards regarding handling of A2L refrigerants The Building and Fire codes cover storage of A2Ls in a warehouse, while the Mechanical code covers requirements for installing equipment that uses A2Ls.   Building code revisions align with established safety standards regarding handling of A2L refrigerants, including ASHRAE 15 (Safety Standard for Refrigeration Systems), UL 484 (Room Air Conditioners), UL/CSA 60335-2-40 (refrigerant detector requirements) and UL/CSA 60335-2-89 (enabling higher charge limits for flammable refrigerants).   requirements of ASHRAE 15 In buildings where HVAC machinery is installed, the code changes reflect requirements of ASHRAE 15, such as no equipment with open flames, elevated temperature limits in a room, and refrigerant detection requirements that trigger a mechanical ventilation system in case of a leak. Any piping that carries A2L must be labeled as flammable with a warning. Condensers and evaporators will need to carry the familiar triangular flammability labels and “risk of fire explosion” verbiage, all consistent with the ASHRAE 15 standard.   Diamond-shaped labeling An interlock requirement ensures ventilation processes are implemented in case “Diamond-shaped labeling must be displayed on packaging, storage, and containers so that anyone coming into a room knows there is flammable refrigerant there,” says Jim Cika, a director of technical resources for the International Code Council.   The codes cover safety requirements such as leak detection, ventilation requirements, and “flammable” labeling. An interlock requirement ensures ventilation processes are implemented in case of a detected leak of A2L gas.  storage and warehousing “The biggest concern is proper storage and warehousing,” says Jim Cika. “Due to flammability, there are significant additional storage requirements compared to HFC. Distributors have to be prepared with appropriate space and labeling requirements, especially when the materials are being stored in bulk and large quantities.”  A2L code provisions The code changes are required to enable builders to transition to A2L refrigerants ICC has created a website that provides relevant A2L code provisions including documents with specific wording related to code changes. Some states adopt the codes state-wide, while other “home-rule” states leave the adoption of the codes to the individual local jurisdictions. The code changes are required to enable builders to transition to A2L refrigerants.   new codes ICC has been publicizing the code changes with the help of a grassroots effort with AHRI. “We have put our code provisions out there so everybody knows what they need to be concerned about and to be ready for inspection,” says Cika. The new codes are coordinated with the EPA and the requirements of the SNAP programs. “We are all on the same page,” he says.  installation of new equipment After 2025, new equipment will no longer use HFCs but will need to use A2Ls or another low-GWP refrigerant Up to 25 lbs. of A2L refrigerant can be transported without any hazardous material restrictions; in effect, installers and contractors can transport A2L just as they did HFC.  Transitioning to A2L refrigerants involves the installation of new equipment since the legacy equipment that uses HFCs is not compatible with the new refrigerants. After 2025, new equipment will no longer use HFCs but will need to use A2Ls or another low-GWP refrigerant. transition to A2Ls Technicians will still be able to service and maintain existing equipment installed in the field for the rest of its useful life. With equipment using both types of refrigerant operating among various customers, technicians will need to be able to work on either type of system during the transition period.  Phased down and limited supplies of HFCs, as ordained by EPA regulations, will likely push installers and their customers to the newer technologies using A2Ls. 

When Mulalley and Co needed to update the existing boilers at its main office in Essex, a new Wessex ModuMax mk3 system from Hamworthy Heating – a trusted British manufacturer and supplier of commercial heating and hot water products – was installed to help maximize space at Teresa Gavin House. With its previous floor-standing system taking up much of the plant room floor at Teresa Gavin House, Hamworthy proposed a system using two Wessex ModuMax mk3 floor-standing, vertically stacked modules with a total power outlet of 464 kW, a new plate heat exchanger and a Chesil pressurization unit. In line with updates to the existing building regulations Part L, a new boiler flue was also fitted as part of the new installation.  New Wessex ModuMax mk3 system The new Wessex ModuMax mk3 system offers a practical alternative to larger floor-standing alternatives. This means that Teresa Gavin House now benefits from increased floor space and improved access to its plant room. Featuring a stainless-steel design for added protection against corrosion, Mulalley and Co. can also expect to benefit from valuable cost savings on future service and maintenance intervals. Keen to stick to a brand they could trust, the new upgrade at Teresa Gavin House replaces seven NGR floor-standing cast iron sectional boilers from Hamworthy Heating that have been in operation for nearly 30 years. Mulalley expects to benefit from valuable cost savings on future service and care intervals Michael Danes, Mulalley and Co. comments, “Hamworthy products offer a robust and reliable solution, backed by an exemplary service and market pioneering warranty. Any minor issues or questions we had during this process were handled quickly and easily by the Hamworthy team. We’re looking forward to seeing the expected benefits of the new Wessex ModuMax mk3 system at Teresa Gavin House.” Reliable and efficient heating system Available in five modules with outputs (@80/60°C) of 97, 116, 147, 196, and 254 kW, Wessex ModuMax modules can be stacked two or three high in up to 15 combinations up to 762 kW output. Providing the benefits of high turndown ratios and load matching for improved efficiencies, the system delivers the right amount of heat at the right time, with little or no wastage. Following a successful upgrade, Teresa Gavin House now benefits from improved efficiencies and increased space within its plant room. Completed in two months, building occupants are now benefitting from a reliable and efficient heating system.

A primary school and bowls pavilion in a South Wales village have switched to clean, renewable heating, but in an innovative way that cannot be replicated anywhere else in Wales. Ffynnon Taf Primary School and the Pavilion at Taff’s Well Bowling Club in Taff’s Well, Wales, have had a bold new heating system installed by Kensa, the UK-based Ground Source Heat Pump specialists, that uses naturally occurring heat from the only thermal spring in Wales – the historic Taff’s Well Spring. This unique water source heat pump system harnesses natural heat from the warm spring water, which emerges from deep beneath the earth at around 21°C, to provide the two council-owned properties with low-carbon heating and hot water. Kensa’s ground source heat pumps  Using the innovative clean heating method instead of gas is expected to cut the school and pavilion’s carbon emissions linked to heating by close to 80%. It also demonstrated a way of using Kensa’s ground source heat pumps without drilling vertical boreholes to access heat energy stored in the ground. The bold idea of using the Taff's Well thermal spring to heat buildings was initially proposed by the Friends of Taff’s Well community group, who were looking at other ways the historic spring could benefit the local community. Renewable heating installations The project follows other retrofit renewable heating facilities met in non-domestic buildings by Kensa This project follows other retrofit renewable heating installations completed in non-domestic buildings by Kensa. Using ground source heat pump technology the UK’s pioneering manufacturer and solutions provider has futureproofed heating and lowered carbon emissions caused by heat in multiple UK schools and council properties. The unique installation also highlights the versatility of Kensa’s ground source heat pump systems and forms part of Rhondda Cynon Taf Borough Council’s ambitious plans to decarbonize by 2030. How the system works Kensa’s ground source heat pumps, found in thousands of UK properties, are usually set up to source energy from the ground to provide heating and hot water. The one-of-a-kind installation at Taff’s Well pumps warm water from the spring and passes it through a nearby heat exchanger, which is connected to Kensa’s ground source heat pumps housed inside the school and pavilion. In this highly energy-efficient system, heat energy stored in the warm spring water is absorbed and converted by the heat pumps into usable energy for the school and pavilion’s heating and hot water systems. While in the system, the water is confined to its own pipework, mostly hidden under the ground and out of sight, and doesn’t encounter any other substances to ensure there’s no issue of contamination or pollution. To keep the connecting pipework hidden and to avoid above-ground damage, Kensa horizontally drilled hundreds of meters between the Well, the school, and the pavilion. After passing through the system, the clean water is emptied back into the Well’s overflow, feeding into the River Taff. This is the only system installed by Cornwall-based Kensa that uses a natural thermal spring as a heat source. New low-carbon heating Kensa’s Dr. Gadsden saw the site, along with reps from Rhondda Cynon Taf County Borough Council On Tuesday, 16th July, Kensa’s Dr. Stuart Gadsden visited the site, along with representatives from Rhondda Cynon Taf County Borough Council, to demonstrate to pupils from the Ffynon Taf Primary School’s Eco Committee how their new low-carbon heating and hot water system works. Dr. Stuart Gadsden, Kensa Contracting Commercial Director, said: “This is an incredibly unique system and really demonstrates how versatile Kensa’s ground source heat pumps are. It was great to show the pupils how their exciting new heating system works and how it will reduce their carbon footprint." Ground source heat pump technology Gadsden added: “Kensa has a proven track record of delivering the high efficiencies of ground source heat pump technology for numerous UK schools and local authorities, providing them with a futureproofed low-carbon heating system." “Using the historic Taff’s Well thermal spring as a renewable heat source is a brilliant example of how bold ideas can lead to something that benefits future generations. It’s something the whole community can be proud of, and we were pleased to play our part in making it happen.” Success of the thermal spring installation Ffynnon Taf Primary School Headteacher, Kathryn Price, said: “We are very excited about how Taff’s Well Thermal Spring has been utilized for the whole school community. Our Eco Committee thoroughly enjoyed learning more about the heat pump system and how this helps to reduce the school’s carbon footprint. We will continue to celebrate the success of the thermal spring installation in our community for many years to come.” Jon Arroyo, Energy and Carbon Reduction Manager at Rhondda Cynon Taf County Borough Council said: “We have the ambition to decarbonize the Council by 2030 and we understand there is no one solution to decarbonize our heating systems, so it is important that we look at what heat resources are around or under us. As a Council, we see our role in exploring alternative solutions to help steer our businesses and residents in their journey towards a net zero future.”

Nearly Bergamo, Italy, there is a weather station that collects meteorological data and monitors air quality. Its operation requires professional equipment that, however, works without a permanent power supply or the presence of staff. Such conditions put the equipment and other assets at risk. In fact, the station had already suffered from several intrusion attempts and needed a security system to be put in place. Challenge Protect a remote object without a permanent power supply Like many remote objects, the weather station does not have a permanent power supply and cannot afford a full-time presence of staff members on the site. After several intrusion attempts, the client needed to secure an area of 600 square meters, prevent equipment theft, and put an end to the damage made to the agricultural produce growing on the site. They looked for a professional security system that could operate outdoors without mains power and was easy to manage remotely.  Solution Wireless outdoor security system with flexible power options and remote control The implemented security system consists of 11 Ajax devices, coupled with a third-party solar panel, battery, and case In response to the challenge, Von Wunster Next s.r.l. configured a solution for securing the object that has no permanent power source or staff on-site but has extensive sun exposure. The implemented security system consists of 11 Ajax devices, coupled with a third-party solar panel, battery, and case. At the core of the system, there is a Hub 2 (2G) Jeweller control panel with a low-voltage PSU 6V. The latter allows the hub to operate from an external 7 A h battery for years. The battery, in turn, is charged via the 25 W solar panel (10 A). If the external power supply fails, the hub switches to a built-in battery and continues to protect the object for up to 16 hours or even 60 hours if the Battery Power Saver feature is enabled. The client and central monitoring station of the security company instantly receive a notification about the power issue to be fixed. The company has enough time to get to the remote object for restoring power without compromising its security. A SIM card (2G) ensures connection with the network, so Von Wunster Next s.r.l. won’t miss a thing. StreetSiren DoubleDeck Other elements of the security system are wireless outdoor Ajax devices that operate with pre-installed batteries for up to 3 years. Several MotionCam Outdoor Jeweller cover the perimeter and detect movement within seconds. The device’s photo-by-alarm feature allows minimizing expensive patrol dispatches to false alarms and gives the client peace of mind. StreetSiren DoubleDeck activates the sound of up to 113 dB and bright LED indicators in response to an alarm to deter and expose intruders. Communication with the wireless devices is provided via Ajax proprietary radio protocols Jeweler and Wings at a distance of up to 2,000 m. It’s perfect for covering large areas such as that of the station. Ajax SpaceControl Jeweller key fobs Dealing with the security system is as easy as it gets for both the client and the security company The client can control security modes effortlessly. There are four end users with different rights, and they can manage the system in the Ajax app on their phones and with wireless Ajax SpaceControl Jeweller key fobs. Von Wunster Next s.r.l., which installed the system and conducts monitoring, can track the devices’ status and take care of their configuration and maintenance remotely in the majority of cases.  Dealing with the security system is as easy as it gets for both the client and the security company. All the devices are either weather-resistant or reliably hidden in the case to withstand the impacts of the environment. Constant exposure to rain or sun does not affect the security system. Why Ajax Flexible power supply options. Ajax's product portfolio includes PSUs designed to connect the system to a low-voltage power supply even when no permanent power source is available. Wireless Ajax devices operate with pre-installed batteries for up to 3 years. Visual alarm verification. With photo verification, system users and monitoring company operators can promptly verify whether an alarm is real and save costs on patrol dispatches. It is a particularly important feature for remote objects. Remote system management. The system can be managed, configured, and maintained through Ajax apps with no people present on-site, which is a cost-effective solution for a remote object.

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.

Water and energy efficiency company Cenergist has been appointed by Ashford Borough Council to provide a nutrient neutrality solution for a new 1,000 home development using its patented Control Flow technologies. The site is within a nutrient-sensitive area that requires any new development to mitigate against increased localized waterway pollution.  Cenergist’s patented Control Flow products are pressure-independent flow controllers that provide long-term reductions in water wastage and nutrient emissions from homes as well as improve the performance of existing gas boilers. By eliminating the fluctuations in the water supply caused by system pressure changes, Control Flow provides a steady precise water flow to the home.  Control Flow installations By installing in existing homes in the area, Control Flow creates the headroom for new builds Performance tested in both the UK and Europe, Control Flow has been shown to reduce water and energy bills by up to £360 per annum with a 98% customer satisfaction rating. By installing in existing homes in the area, Control Flow creates the headroom for new builds.  Under the contract, Cenergist will determine the precise number of Control Flow installations required to offset all the nutrient emissions from the new development at Ashford. Working with the council, it will then contact and persuade householders of the benefits of the technology and then carry and complete the installations and provide the necessary assurance to allow Natural England to sign off on the development. The project follows on from the use of Control Flow to unlock a development in Crawley that had previously been held up due to water scarcity concerns. Nutrient neutrality strategies Paul Mckenner, head of strategic projects at Ashford Borough Council, said: “The retrofitting works is part of a series of measures to unlock approximately 1,000 new dwellings which the Council has a vested interest in.” In England, waterways including lakes, rivers and estuaries are protected under the Conservation of Habitats and Species Regulations 2017. Natural England has mandated that developments located near vulnerable watercourses require nutrient neutrality strategies to prevent negative ecological impact." Caroline Gray Mason, business development director at Cenergist commented: “Nutrient neutrality is a significant challenge facing developers as they look to deliver much-needed housing in a sustainable, responsible way. It is essential to be on the front foot with nutrient mitigation measures to minimize the environmental impact of new developments in vulnerable areas. Securing this contact with Ashford Borough Council is a testament to Control Flow’s role to mitigate nutrient pollution by reducing the level of emissions from existing homes.”

With nearly nine out of ten new school sites above the World Health Organization (WHO) targets on major air pollutants, Elta is urging decision makers for schools’ building services to address the problem through a ‘three-step’ process to ventilation specification and maintenance. The callout follows a study led by researchers from Evelina London Children’s Hospital and King’s College London (KCL). Following their analysis of 147 new school locations around England that were to be built between 2017 and 2025, the researchers found that 86% of those sites exceeded air quality targets. Those targets are for particulate matter PM2.5, PM10, and NO2 (Nitrogen Dioxide), pioneering to the conclusion that air quality around new schools is “alarmingly poor”. Three steps to prevent poor air  With emerging studies also showing that poor air quality leads to lowered cognitive growth With emerging studies also showing that poor air quality leads to lowered cognitive growth, Elta, UK’s pioneering experts in ventilation equipment, outlines three measures to tackle the problem. The three steps are aimed at preventing poor air from entering the school building and classrooms, including: Installing air monitoring equipment in schools to identify concentrations of particulate matter, nitrogen dioxide, and other contributors to poor air quality Using correctly specified mechanical ventilation systems to process and filter air of harmful particulate matter and substances, to bring indoor air quality to a safe level Having a robust maintenance schedule in place to clean ventilation equipment on a regular basis Decision-makers for building services David Millward, Group Product Manager at Elta Group, the parent company of Elta, said: “This latest study by Evelina London Children’s Hospital and King’s College London is a harsh wake-up call to everybody in the country and is a reminder that poor air quality has a real detrimental effect on children. Not only is it harmful from a health perspective, putting pupils with respiratory conditions like asthma at higher risk, but poor air also impairs children’s learning and ability to concentrate. “While outdoor air is hard to regulate, there are some immediate steps that decision-makers for building services can take to improve indoor air quality in schools. Through three simple steps of air quality monitoring, correct specification of mechanical ventilation systems, and regular maintenance of these systems, we can at least prevent poor air from making its way into the classroom.” Framework for ventilation Framework for ventilation in schools and recommended performance levels to comply with UK regulations David highlights that ‘Approved Document F – Ventilation – Volume 2’ of the Building Regulations gives guidance about air quality monitoring requirements in buildings other than dwellings.  Meanwhile, ventilation decision-makers for schools should follow the guidance given in the UK Government’s Building Bulletin, BB 101, to understand the framework for ventilation in schools and recommended performance levels to comply with UK regulations. David also urges those in charge of building services for schools to collaborate with ventilation experts to ensure best practices and compliance is achieved. Effects of poor air quality David concluded: “With better collaboration across the supply chain, we can protect the next generation from the effects of poor air quality, and improve indoor air quality across new schools, as well as old." "At Elta, our ventilation experts are always available to help provide guidance and help design ventilation systems, either for newly built schools or for retrofitting to existing school stock.”

The HVAC market is a rapidly changing environment on a variety of fronts, from the introduction of new refrigerants to the increasing use of artificial intelligence to the embrace of interconnected systems in the Internet of Things (IoT) environment. We asked our Expert Panel Roundtable: How will the HVAC market change in the next five years?

For schools, improving indoor air quality (IAQ) is a basic function of HVAC systems, which also ensures a high comfort level for students, teachers and staff. Schools can be a lucrative market for HVAC systems, but there are challenges, such as long sales cycles and the lingering impact of the COVID-19 pandemic. We asked our Expert Panel Roundtable: What are the challenges for HVAC in serving the education/schools market?

The practice of working from home soared during the coronavirus (COVID-19) pandemic and many observers see a likely continuation of the trend, as infection risks gradually subside. Both environments – home and office – depend on HVAC systems to keep occupants comfortable (and safe!). Therefore, the industry stands to be impacted whichever way the trend plays out. We asked our Expert Panel Roundtable: How will remote working affect residential and commercial HVAC?
