Nidec Global Appliance’s booth at AWE 2025 - one of the world’s largest home appliances and consumer electronics trade shows - held from March 20 to 23, 2025, in China, was the stage for the launch of the new Embraco residential refrigeration compressor: the Embraco Atom. It stands to be the most compact variable-speed compressor for residential applications on the market, designed to democratize this energy-efficient technology. The product was granted the AWE Innovation Award during the event. Range of refrigeration applications Weighing just 2.5 kg and measuring less than 110 mm, it is 30% lighter than Embraco’s previously most compact compressor, the FMS. It was designed to be competitive enough to accelerate the migration from fixed-speed to variable-speed technology, being accessible to a wide range of refrigeration applications, from premium models to single-door refrigerators and beverage coolers. Crucial role in transformation Weighing just 2.5 kg and measuring 110 mm, it is 30% lighter than Embraco’s previous compressor Alberto Casnati, President of Nidec Global Appliance, explains, "There is a growing global push for increased energy efficiency, driven by economic, social, and environmental motivations, and variable-speed technology plays a crucial role in this transformation, especially in refrigeration appliances. This technology enables compressors to adjust their speed based on demand, resulting in significant energy savings compared to traditional fixed-speed systems." He adds, "The Atom was developed as a global platform to support the widespread adoption of variable-speed technology, and our initial key markets include China, Europe, and India. At the same time, Atom has been meticulously engineered to lead in sound performance, both in terms of sound level and sound quality." Benchmark for low-noise compressors Alberto Casnati continues, "It also sets new standards for compactness, allowing more usable space inside the appliance, a key benefit for maximizing food storage. Thanks to its innovative and space-efficient design, Atom is setting a new industry benchmark for low-noise compressors." Energy consumption regulations The product runs on natural refrigerant R600a, and has a coefficient of performance of up to 1.90W/W The product runs on natural refrigerant R600a, and has a coefficient of performance of up to 1.90W/W, an indicator of its energy efficiency that shows it is capable of meeting the most stringent energy consumption regulations of any region in the world. Its efficiency level allows the Atom to reduce energy consumption by more than 25% compared to a traditional fixed-speed compressor. Innovative technical solutions The Atom features innovative solutions to meet bold design targets of size, low noise, and energy efficiency established in its research and development process. One of them is the polymeric discharge line, which replaces the traditional metal discharge tube, allowing the reduction of the compressor’s size, as well as decreasing heat dissipation, vibration, resonance and noise, without compromising performance. “Making such a small compressor is an engineering challenge. And we are reducing the size without affecting reliability, efficiency, capacity or robustness,” summarizes Alberto Casnati. Standard market compressors The Atom comes with an ultra-compact inverter, which is the component that controls speed Another technological breakthrough is the electronic component. The Atom comes with an ultra-compact inverter, which is the component that controls the compressor’s speed. This specific model is capable of intelligently extracting peak performance from the compressor and actively controlling its vibration levels, making it more silent. The Atom reduces up to 5 dB compared to standard market compressors. Interior space in the refrigerator The small size has additional advantages linked to logistics, such as allowing twice as many compressors per pallet versus market alternatives, which reduces emissions caused by transportation, and demands less storage space. It also reduces resource consumption during production. Another positive outcome of such a compact compressor is to maximize interior space in the refrigerator and allow more design flexibility to appliance manufacturers, even for special applications, such as two compressor systems or refrigerated drawers.

Teledyne Gas & Flame Detection (Teledyne GFD) is making its final preparations for a trio of forthcoming energy sector events taking place in Europe and Asia. Visitors to the Teledyne GFD booth at All Energy 2025 (Glasgow, UK, 14-15 May), World Hydrogen Summit 2025 (Rotterdam, Netherlands, 20-22 May) and World Gas Congress 2025 (Beijing, China, 19-23 May) will learn for themselves the advantages of tapping into sector knowledge and solutions that stem from decades of empowering safety in all forms of power generation. Key for these events will be Teledyne GFD’s hydrogen detection expertise and technologies. low-carbon energy and renewables event The All-Energy exhibition and conference is the UK’s largest low-carbon energy and renewables event, with hydrogen among key focus areas regarding both grid integration and battery energy storage systems (BESS).  Hydrogen is produced in BESS systems during the charging and discharging process of the batteries, or if a fault occurs that leads to thermal runaway. Once initiated, thermal runaway will likely result in a fire, but with the right detection technology it is possible to contain the consequences. Spyglass™ Xtend triple-infrared flame detector Integrated high-definition CCTV video delivers clear, rapid imaging of fuel fires like gasoline and jet fuel On stand B39, Teledyne GFD, which has its UK manufacturing facility just 8 km west of Glasgow in Renfrew, will be shining the spotlight on four key technologies. The recently introduced Spyglass™ Xtend triple-infrared flame detector offers the simultaneous detection of both hydrogen and hydrocarbon fires. It boosts safety in environments where hydrogen flames can spread to co-located systems or nearby equipment and start fires involving hydrocarbon fuels that are invisible to a hydrogen-only detector. Integrated high-definition CCTV video delivers clear, rapid imaging of fuel fires like gasoline and jet fuel, while the near-IR video option detects fires caused by hydrogen and methanol, making it ideal for BESS applications. Five selectable sensitivity levels are available. Utility grid integration projects Other instruments of note at All Energy 2025 will include the tried and tested GD10P infrared (IR) gas detector, as well as the GS700-Hydrogen, a high-performance and highly flexible all-in-one instrument that is able to detect both hydrogen and natural gas in utility grid integration projects. Fully ATEX-certified instrument means utilities can quickly determine the source of gas leaks Whether it is 100% hydrogen, hydrogen blends, or natural gas, the portable GS700-Hydrogen simplifies gas detection in applications that include outdoor/indoor leak detection, purging, barholing, and pipeline gas testing. Providing both safety and peace of mind, the fully ATEX-certified instrument means utilities can quickly determine the source of gas leaks, saving valuable time and reducing detection-related costs such as unnecessary excavations. Teledyne GDCloud’s capabilities Also on show will be Teledyne GDCloud™, a user-friendly new cloud solution that enhances gas detection measurement by recording hazardous events. Users can take advantage of this technology to help ensure regulatory adherence and streamline safety programmes. Among Teledyne GDCloud’s most powerful capabilities is visualizing detailed gas sensor readings from field sessions. Users can trace the route that a technician takes during investigations via advanced location mapping functionality. This capability enables breadcrumb mapping to identify the exact locations that correspond to gas readings logged by the detector. Teledyne GFD’s expertise Users can also interact with dynamic charts and tabulated data displays to reveal further insights Users can also interact with dynamic charts and tabulated data displays to reveal further insights into field activity and events. The same four technologies will also take center stage at the World Hydrogen Summit 2025, where visitors will find Teledyne GFD at booth A93. In fact, such is Teledyne GFD’s expertise in the hydrogen arena that it has been invited to deliver a presentation at the event entitled ‘Regulatory Framework and Compliance along the Hydrogen Value Chain’. Future gas detection challenges At World Gas Congress, a flagship gas and energy industry event staged once every three years, Teledyne GFD will again present these technologies to visitors from booth Z12 in hall D. A team of local experts will be present to discuss current and/or future gas detection challenges. Further reflecting its strong global presence, Teledyne GFD will also take booths at two events in the United States during May: AGA (American Gas Association) 2025 on May 4-8 in Aurora, Colorado; and OTC (Offshore Technology Conference) 2025 on May 5-8 in Houston, Texas.

As demand continues to grow for sustainable, energy-efficient solutions in refrigeration and heating, both Europe and North America are navigating a rapid transition toward natural refrigerants. There is a strong demand for new CO2 systems, including heat pumps and various other applications. Higher capacity compressors with larger operating envelope, such as Danfoss’ Bock HGX56 CO2 T series, will play a critical role in supporting this growing need. Air to water heat pumps As shown in Figure 1 and Figure 2 below, the larger operating envelope of up to 77°F and 65 bar on the suction side can improve the COP by approximately 15% for applications with higher heat source temperatures – for example, air to water heat pumps in summer conditions. Transcritical CO2 figure. Larger operating envelope of up to 77°F and 65 bar on the suction side. Figure 3 below shows a typical layout of a CO2 transcritical air-to-water heat pump for large systems, designed with features to boost efficiency. Such systems are already being built in Europe, with the largest compressor options, and used in heating capacities of up to 2.5 MW per rack. Layout of a CO2 transcritical air-to-water heat pump for large systems. Cooling and Heating Working Together Transcritical supermarket applications with heat reclaim are very suitable for improving the version Transcritical supermarket applications with heat reclaim are very suitable for improving the overall refrigeration system performance. It is a highly efficient and resilient solution that provides simultaneous heating and cooling by recycling waste heat energy within the store. More than 2,000 installations across Europe and in other parts of the world have shown that the traditional CO2 weaknesses in refrigeration applications, such as high temperatures and pressures, can be turned into profitable advantages when adding heat reclaim to the system. In fact, the operational costs can be reduced by more than 20% by replacing conventional heating sources with heat reclaim, and the pay-back time of the heat reclaim installation is typically short, less than 2.5 years. At the same time, huge carbon savings can be made when the system is installed and maintained correctly. Additional Applications Transitioning to CO2 CO2 is increasing in popularity for cold storage and food processing, due to some challenges of using ammonia in states with a large number of regulations, as well as the desire for distributed systems when expanding plants and the advent of larger CO2 compressors. Some estimates show a 10% market transition to CO2 from ammonia and HFCs for systems up to 250 tons (880 kW). An example would be a cold storage facility requiring variable temperatures with stability/efficiency at partial load for garlic processing, storage and pre-cooling. The requirements for pre-cooling are 40°C/39.20°F, but for processing and final storage, −100°C/140°F is required. CO2 System Examples Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration. They can be operated very efficiently, if the high pressure is operated in the subcritical range over a long period. Using the high-pressure side, it is appropriate to use the application in the transcritical range in combination with refrigeration, due to a large temperature glide and a relatively high discharge end temperature for specific heat pumps and the heat recovery. In CO2 applications in low and medium temperature refrigeration, so-called booster systems are used. High-pressure CO2 gas from the low-temperature compressor is discharged directly to the suction side of the second compressor stage. Different plant constructions of these Booster applications are used, for example, in supermarket applications. In a cascade system, different refrigerants are used in an application. They are combined in two refrigerating circuits that are separated from each other. The high temperature stage is used as a condenser in the CO2 application. It is possible to use different refrigerants like hydrocarbons, ammonia, and HFCs like R-134A. Keys to a Successful Installation Proper oil levels, adequate space for maintenance and ventilation, environmental conditions and surface setup with sufficient load-bearing capacity are all critical initial items to consider. Once these items have been considered and addressed properly, then you need to take extreme care during the soldering - cooling the valve body during and after and only using inert gas to inhibit oxidation products. The actual required pipe cross-section must be matched to the output. The tube must be sawed at a right angle with the angular tolerance being ±10. Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use hermetically sealed parts. Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations. Ensure a proper oil return and keep pressure loss to an absolute minimum. Suction and discharge should be depressurized prior to connecting to the refrigerant system. Proper layout of the suction and pressure lines directly after the compressor is integral to the smooth running and vibration behavior of the system. Oil return function To ensure the oil return function will work reliably no matter what kind of system configuration you are using, Danfoss recommends incorporating oil separators or oil level monitoring equipment. For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. When attaching accessories with an electrical cable, a minimum bending radius of 3x the cable diameter must be maintained for laying the cable. Voltage and frequency values Compare the voltage and frequency values with the data for the mains power supply Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box). Compare the voltage and frequency values with the data for the mains power supply. Only connect the motor if these values are the same compressors marked in this way are suitable for direct or part winding start.  The motor winding is divided into two parts: part winding 1 = 50 % and part winding 2 = 50 %. This winding division reduces the start-up current during a part winding start to approx. 50 % of the value for a direct start. Reversed fields of rotation In the factory, as shown below in Figure 4, the motor is switched for direct starting (YY). For part winding start (Y/YY), remove the bridges and connect the motor feed cable according to the circuit diagram. The motor is switched for direct starting (YY). Failure to comply results in reversed fields of rotation and can cause motor damage. After the motor has started up with part winding 1, part winding 2 must be switched on after a maximum 1-second delay. Failure to do so can be detrimental to the service life of the motor. Ensure that power is supplied via QA2 to winding 1 (50%) (1U1/1V1/1W1) and via QA3 to winding 2 (50 %) (2U1/2V1/2W1). The motor contactors (QA2/QA3) are each to be rated for approx. 50% of the maximum operating current. Danfoss BOCK compressors Transcritical CO2 compressors, like the Danfoss BOCK product line, offer a wide span of capacities with up to 162 kW of cooling capacity (14°F/95°F/18R/60 Hz) and 420 kW of heating capacity (41°C/77°C (100 bar)/18R/60 Hz) for many different product applications, including food retail, heat pumps, district heating, industrial refrigeration and process heating, reversible chiller/heat pumps for HVAC, cold storage, chillers, and data centers. Low and medium temperature levels are available, with high stand still pressures. This high capacity reduces the need for multiple compressors, simplifying system design and reducing investment costs. The Danfoss BOCK compressors also feature a high-pressure rating of 130 bar in operation/150 bar at stand still on the high side and 65 bar in operation/100 bar at stand still on the low side.

Although energy efficiency continues to be a focus of home renovation, HVAC professionals are sometimes hesitant to work on older homes. The potential costs and complexities of replacing outdated HVAC systems or installing a solution where one doesn’t exist can make them nervous. However, installing all-electric, all-climate heat pumps in homes built decades ago, even a century ago, is an everyday occurrence in the northeastern U.S. Heating and cooling systems A sizable portion of Jay Moody Heating & Air Conditioning consists of installing and servicing energy-efficient heating and cooling systems, especially heat pumps, in older homes in central Massachusetts. Updating older homes with heat pump solutions is more feasible than many think — it’s a matter of overcoming common barriers and being the right, experienced HVAC professional for the job. Common barriers when heating and cooling an older home In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes Barriers to renovating older homes are surmountable. Commonly, older homes lack adequate filtration and insulation and are equipped with older electrical panels that might need upgrading or replacing.  In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes. However, whether an older home is heated with oil or gas, outside air infiltration occurs because these structures generally lack a tight building envelope. More recently built homes have these systems to prevent outside air and water from penetrating the structure. Similarly, many older homes are insufficiently insulated. Size of the structure and other electrical loads As a first step, owners of older homes should get an energy audit and find out what can be done to eliminate infiltration, such as having air sealing performed and having more insulation blown into their houses. Once weatherization is complete, installing an all-electric heat pump system becomes more feasible. Another important requirement would be an appropriately sized electrical panel. Older homes might have 100 amps of service, for example, when it will need 200 amps for the new heat pump, depending on the size of the structure and other electrical loads such as electric stoves/ovens, water heaters, and electric vehicles. In some cases, an electrical panel upgrade may be required. Attributes homeowners look for in an HVAC company HVAC companies that specialize in heat pumps should ensure their HVAC technicians are shared and ongoing training When upgrading an older home with a heat pump system, it’s a best practice for homeowners to get multiple quotes from experienced contractors in their service area. To stand out and offer more value during this process, my business conducts monthly heat pump workshops that help educate customers. Additionally, I recommend that any experienced, reputable HVAC company should post online reviews, have a professional website and online presence, and show relevant work examples to help familiarize homeowners with their work. HVAC companies that specialize in heat pumps should ensure their HVAC technicians are experienced and undergo ongoing training. In fact, the Jay Moody team is part of the Mitsubishi Electric Diamond Contractor® program, which provides in-depth training on heat pump solutions. Homeowner’s comfort preferences During the in-home consultation, the salesperson should discuss the homeowner’s comfort preferences, HVAC concerns, and short- and long-term plans for the home and its HVAC system. The contractor should conduct an in-house Manual J to calculate the heating and cooling loads of the home, ensuring proper HVAC equipment sizing for efficient and comfortable performance. Lastly, the HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. For instance, my team would not use mini-splits in certain rooms in a Victorian home because they might detract from the style. Instead, they would likely suggest a ducted heat pump system with air handlers and stylish vents. HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. Heat pumps offer the right fit for homes of all ages In the Northeast, many of the homes are older – whether that means built in the 1960s, the 1860s, or the 1760s. There’s little reason that any HVAC contractor should shy away from installing heat pump systems in older homes. Further, contractors can learn how to teach homeowners about heat pumps, train their teams, and recommend the right system for the character of the house. Refurbishing these beautiful houses is a challenge well worth tackling to create homes as energy-efficient and comfortable as they are charming.

Training has always been important in the heating sector, not least of all because of the dangers associated with working with gas, the traditionally dominant heating fuel in the UK. With the changes that are occurring across the heating industry, primarily the move towards decarbonization, manifesting in a transition to heat pumps, training is more important than ever. Principles of heat pump technology Training could take the form of a CPD on understanding the guides of heat pump technology That training could take the form of a CPD on understanding the principles of heat pump technology through to specific product training addressing installation, commissioning, and maintenance. Commercial heating training courses are abundant. Unless there is a specific manufacturer’s product you want to train on, how do you choose a training course and provider that is right for you? Here, we look at the key aspects to consider when selecting a training course and training provider. Expertise & knowledge By far the most important aspect of any training is the level of expertise and knowledge of the training providers. The training course needs to be both written and delivered by people who have direct experience in the heating industry. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For contractor-based training, ideally, the trainers will have a background in heating engineering. This enables them to not only cover the core content of a training course but also address how it applies in real working-life situations. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For specifiers looking to expand their knowledge through CPD courses, it’s helpful if these are presented by experienced Specification Managers who understand the needs of a specifier and have extensive knowledge of heating systems. On-site facilities The environment itself plays an important role in the success of the training The environment in which you learn plays an important role in the success (or otherwise) of the training itself, which is often overlooked. Being in a comfortable environment free from distractions will support you to better focus on your learning. Is the training held in a dedicated training center or a makeshift back office room? Is it a comfortable environment in terms of seating, desks, heating/air conditioning? Is the presentation equipment up to scratch? But most important of all, is the heating equipment you are learning about present, and is it functional? Training and Technology Centers  At our Training and Technology Centers, we provide learners with on-site access to a range of commercial heating equipment, including a unique thermodynamic heat pump simulator where they can view the change of state of refrigerant when in operation. Hands-on training for contractors is vital as it enables more learning by doing and problem solving, and therefore, greater depths of understanding can be gained. In our feedback survey, this comes up as one of the most important and popular aspects. It’s one thing to have something presented to you, but to be able to work through scenarios with expert support is quite another. Hands-on training for contractors is vital as it enables more learning by doing and problem-solving. Location A CIBSE-approved CPD, for example, doesn’t require hands-on training We’ve looked at the importance of how a training course is delivered, but where it is delivered also has a role to play. Does the training provider have training facilities nationwide, or in just one location? The latter could make for long travel times and even an overnight stay. Ideal Expert Academies are located around the UK at Hull, Leeds, Dalgety Bay, and Luton. Lastly, not all training needs to be done in person. A CIBSE-approved CPD, for example, doesn’t require hands-on training. In these instances, online training is a good, convenient option. Will the training provider be able to deliver this and how? Is it just a PowerPoint presentation, or are other elements included, such as video, attendee tasks, etc? Range of courses and delivery Having a range of courses is obviously important in that it provides you with choice and allows you to fill in the gaps of your knowledge, as well as learning about emerging technologies and best practices. A good training provider will also provide a flexible delivery model to meet individual learner needs and have the knowledge and expertise to support those with learning difficulties. Good training provider also provides a flexible delivery model to meet individual learner needs. Endorsement Ideal Heating’s adult learning provision was assessed by Ofsted, and they received an excellent report Whilst it’s important to do your own ‘homework’ on training providers, third-party endorsements are very useful. These come in different forms, from customer feedback (there are plenty of forums that provide you with the opportunity to ask for feedback), through to recognized industry awards, and independent assessment. Last year, Ideal Heating’s adult learning provision was assessed by Ofsted, and we received an excellent report, plus our Expert Academy team was recognized as Training Partner of 2024 by Hull City Council for delivering Skills Bootcamp programs for hundreds of learners in the area. We were also delighted to receive the inaugural BESA award for Training Provider of the Year 2024. Cost The last aspect I want to touch on when it comes to training is cost. How much should you pay for training? You should really consider the value you believe will be returned from the program and the provider you choose.  If you are going to benefit from state-of-the-art facilities, you may probably expect that experience may cost more than somewhere very simple and basic. Training providers are businesses, and the good ones do invest heavily in facilities and staff development. The good ones do invest heavily in facilities and staff development. Ideal Heating as a manufacturer strongly believe that our training services are part of what we deliver in our product sales. For this reason, we provide many of our training programs for free or at very low cost, despite the significant investment into our resources. Working alongside our specifiers and installers to meet their training needs builds for a strong relationship and successful projects. Choose wisely Taking time out from your busy schedule to dedicate to training is an investment, financially in some cases, so selecting your training course wisely to maximize that investment is sensible.

Viessmann Climate Solutions (VCS) has combined with Carrier to become the core of Carrier’s newly formed business unit Residential and Light Commercial for European, Middle East and Africa. This business unit is now able to offer brands like Carrier, Toshiba, and Beretta next to the premium brand Viessmann, thus covering additional user segments with differentiated products at various price points. Climate system technology “The climate system technology of Viessmann Climate Solutions and the cooling-focused systems of Carrier combine two core competencies that will be crucial in responding to individual customer needs worldwide,” says Thomas Heim, President, Residential & Light Commercial HVAC for Europe, Middle East, and Africa. “Carrier expands the Viessmann portfolio in the area of air conditioning and enables seamless integration of heating and cooling.” Carrier’s acquisition of Viessmann Climate Solutions There was huge media interest in Carrier’s buy of Viessmann Climate Solutions when it was revealed There was huge media interest in Carrier’s acquisition of Viessmann Climate Solutions when it was announced more than a year ago. In media interviews, Carrier Chairman & CEO David Gitlin; Max Viessmann, CEO and Member of the Executive Board of the Viessmann Group, which owned Viessmann Climate Solutions prior to Carrier’s acquisition; and Heim presented the many advantages the combination would bring. Advantages apply both to the product portfolios, which perfectly complement each other, and to the optimized development of global markets. A year later, the feedback is extremely positive, says Heim. Latest developments in the Viessmann system The sentiment was confirmed by numerous conversations with installers at the ISH 2025 trade fair in March in Frankfurt. “The advantages of this combination between Viessmann Climate Solutions and Carrier are clearly noticeable for everyone involved,” says Heim.   The latest developments were well received by the 100,000 visitors to the booth at ISH, with particular interest in the Viessmann system connecting several products into a solution based on full stack controls platform Viessmann One. Residential and commercial sector customers The alliance meets the needs of residential and commercial sector clients with a multi-brand portfolio Also at ISH, Viessman highlighted the newly created alliance of Viessmann, Carrier, Riello, and Beretta around the theme “Power Play as One Team.” The alliance meets the needs of both residential and commercial sector customers with a multi-brand portfolio of heating, ventilation and cooling solutions for all output ranges and price levels. “Together with Carrier, we are in an even better position to provide solutions that address climate challenges by reducing CO₂ emissions and increasing energy efficiency,” says Heim. Digital tools and ecosystems The expanded product line builds on the strong longstanding collaboration of Viessmann Climate solutions with installation partners. For example, the addition of (light) commercial Carrier heat pumps to the portfolio enables leveraging together existing digital tools and ecosystems with this expanded offering. “This increases the relevance of our ecosystems for both our installers and users,” says Heim. Culture of collaboration The focus from the start has been on creating a culture of collaboration among both teams When integrating companies, it is always about bringing people together and providing a framework that allows them to unlock their full potential, says Heim. Thus, the focus from the beginning has been on creating a culture of collaboration that allows the teams from both companies to contribute their unique talents and strengths. “We are convinced that we have found the right formula and that combining Carrier and Viessmann Climate Solutions will lead to 1 + 1 > 4,” he says. “To get there, our shared purpose and values play an important role in this successful integration.” Carrier product portfolios “Companies can only be successful if they think and act globally and operate in a spirit of co-creation,” says Heim. Combining the Viessmann Climate Solutions and Carrier product portfolios creates added value for all installation partners and users. The increasing complexity of the HVAC industry is contributing to a trend toward company consolidation. “Let's be honest: in the past, you simply installed a gas boiler,” says Heim. PV installation They also offer a design tool on the Internet and even financing with the help of a partner bank Heim added: “Today, it's often about heat pumps, battery storage, photovoltaics, wall boxes and an energy management system that links everything together. It's all extremely complex. That's why we are constantly training our installers and at the same time reducing their workload." "Many of our installers don't want to climb on a roof, which is fine. We then look for facilitating a service provider that adds the PV installation to the holistic offering of our partner company.” They also offer a configuration tool on the Internet and even financing with the help of a partner bank. Climate-neutral by 2050 Data centers will also play a bigger role in the future. For example, a typical office building in Manhattan requires only three cooling units, while a data center they are currently working on requires 140. An AI chip generates seven times more heat than a conventional chip. “This market is huge, and we are determined to play an important role,” says Heim. The building sector produces 40 percent of CO2 emissions in Europe. Therefore, a transformation to renewable energies is necessary to become climate-neutral by 2050. Viessmann products and systems “For us, as a manufacturer, this means that we continue to encourage the building electrification system strongly,” says Heim. Viessmann products and systems offer installers the basis for a sustainable climate solution offering for their users. Almost all areas, from single- and multi-family houses to commercial and industrial buildings and municipal facilities, can be covered by the system portfolio. New hydraulic interface Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU) Heim highlights three notable products as part of the Viessmann System Solution. Users can now choose between the high-efficiency, high-comfort Vitocal 250-A and the more economical Vitocal 150-A domestic air source heat pumps. Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU). This high level of flexibility pays off for the installers in significantly shorter installation times, and users only pay for what they actually need for their heating system. The new hydraulic interface also saves time during installation. Vitocharge VX3 storage unit The Vitocharge VX3 storage unit is one of the most proven battery storage units in its class. Its maximum storage capacity of 75 kWh (5 modules of 15 kWh each) is particularly suitable for large, detached houses and apartment blocks, as well as for smaller commercial applications such as supermarkets or craft businesses. Following on from the large power classes, the smaller modules can now also be cascaded at 4.6 kVA. Flexible installation options are now available, including corner or horizontal mounting, which allow for optimal adaptation to on-site conditions.

Data centers play a pivotal role in supporting the flow of information across our digital economy. However, the transmission of large amounts of data also requires a lot of energy. Viewing data centers as potential heat sources offers an opportunity to use this otherwise wasted heat to warm nearby homes and businesses using technologies like heat pumps and heat networks. The approach will lower the environmental impact of these buildings filled with computer servers, and it will support the transition to renewable heating as we look toward net zero. Heat recovery systems Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps and heat networks, says Simon Prichard, EMEA ITC Business Leader, Mitsubishi Electric, within the Living Environmental Systems division. The heat generated by data centers, usually around 30-35°C (85-90°F), is increased by heat pumps to 70-80°C (160-175°F), making it suitable for heating nearby buildings or supplying hot water. “However, when choosing which heat recovery approach to go for, it's important to take into account the data center’s size, location, and proximity to the desired reuse location,” says Simon Prichard, adding “These factors determine the most efficient method for heat recovery and distribution.” Reusing heat from data centers via heat pumps “Reusing heat from data centers through heat pumps and heat networks drives down costs by reducing the amount of heat going to waste and ultimately increasing energy efficiency,” continues Simon Prichard. However, Simon Prichard emphasizes these cost benefits must be communicated and outlined clearly to ensure stakeholders are aware. More awareness will, in turn, drive adoption forward. Wider awareness and adoption Wider awareness and adoption are already happening with plans for utilizing waste heat within London's district heating networks, notes Prichard. The scheme uses ejected heat from a data center to power heating demand for nearby homes A real-life example is Amazon’s Tallaght data center in Dublin, which is the country's first low carbon district heating network. The scheme uses ejected heat from a data center to power heating demand for nearby homes, and peak requests in winter are satisfied by dedicated heat pumps and a heat pump module. The network is estimated to reduce pollutant emissions in the South Dublin County region by nearly 1,500 tons per year. Mitsubishi Electric’s CPD-Certified Guide Mitsubishi Electric’s newly released CPD-Certified Guide aims to educate data center owners, managers and policymakers on the role heat reuse can play in decarbonizing these buildings. “It provides insight into how we can reduce the carbon footprint of these spaces by viewing them as a source of heat energy, as well as the solutions available and what needs to be considered before making the switch,” says Simon Prichard, adding “In doing so, it aims to support owners and managers in transitioning to heat recovery in their building and reducing the environmental impact of these spaces to support the United Kingdom’s wider journey towards net zero.” Communicating the benefits of heat reuse in data centers “Communicating the benefits of heat reuse in data centers can promote greater cooperation from stakeholders – whether that's owners and managers, governments, or manufacturers,” says Simon Prichard. Raising awareness of the environmental impact of data centers and the role heat recovery can play in reducing that impact can position data centers as part of the solution for a decarbonized future. Developing heat networks “Continuing to develop heat networks at the same scale as other European countries will also help make reusing this energy to heat surrounding buildings a reality and put what we see across other countries into practice in the UK,” states Simon Prichard.

Does anyone still think that heat pump technologies for residential applications are ineffective in cold climates? If so, they are missing opportunities available through advancements in heat pump technology. New developments in heat pumps are significantly transforming the residential HVAC market. These advanced heat pumps can maintain 100% heating capacity at 0 degrees F and operate efficiently at low temperatures. Secondary heat sources These capabilities reduce the need for secondary heat sources, leading to lower energy consumption and a reduced carbon footprint. By leveraging variable-speed technology and intelligent controls, newer systems optimize energy use, providing homeowners with both comfort and sustainability. Modern heat pumps, such as Carrier's Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence, are designed to operate efficiently at temperatures as low as minus 23 degrees F, according to Carrier. Energy savings and total comfort  Additionally, for those homeowners who are hesitant to make a full swap, dual fuel technology “These systems provide reliable heating even in the harshest conditions, often eliminating the need for secondary heat sources,” says Nick Arch, Carrier’s Vice President and General Manager, Residential Solutions. Additionally, for those homeowners who are hesitant to make a full swap, dual fuel technology, in which a heat pump is paired with a gas furnace, offers an optimal solution. “The system defaults to the gas furnace depending on the outside temperatures, allowing homeowners to experience energy savings and total comfort in harsh climates,” says Arch. “By leveraging advanced technologies, heat pumps now offer a sustainable and efficient solution for year-round comfort in any climate.” Cold Climate Heat Pump Challenge Driving innovation in heat pump technology has been the participation by Carrier and other manufacturers in the U.S. Department of Energy’s (DOE) Cold Climate Heat Pump Challenge. The challenge required heat pumps to operate efficiently at temperatures as low as minus 15 degrees F, pushing manufacturers to innovate in areas such as variable-speed compressors and advanced controls. Carrier's Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence was developed as part of this initiative and has demonstrated exceptional performance in harsh climates. Benefits of newer technologies  Carrier has established state-of-the-art training centers, such as one in Indianapolis “Carrier's successful completion of the challenge underscores our commitment to delivering high-efficiency, reliable heating solutions for cold climates,” says Arch. Carrier is also committed to educating both the dealer/installer community and consumers on the benefits of newer technologies through various initiatives. Carrier has established state-of-the-art training centers, such as one in Indianapolis, to provide hands-on training and certification programs. operation of new heat pump systems Additionally, Carrier offers online courses and resources through its My Learning Center, covering topics such as new refrigerants, system installation, and maintenance. For consumers, Carrier provides detailed information on its website and through marketing campaigns, highlighting the energy efficiency, environmental benefits, and advanced features of its latest heat pump technologies. Intelligence plays a crucial role in the operation of new heat pump systems. For example, Carrier's Greenspeed Intelligence integrates advanced sensors and controls to optimize the performance of heat pumps. It allows the system to adjust its output based on real-time conditions, ensuring maximum efficiency and comfort. Cold Climate Heat Pump with Greenspeed® Intelligence Carrier is expanding the capabilities of dealer/installers via its Connected Portal For instance, the Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence can modulate its capacity between 30% and 100%, providing precise temperature control and reducing energy consumption. This intelligent operation enhances the overall reliability and efficiency of the system. When it comes to heat pump technology, Carrier is expanding the capabilities of dealer/installers through its Connected Portal, advanced diagnostic tools, and the integration of InteliSense Technology. Remote monitoring capability The Connected Portal allows dealers to monitor HVAC systems remotely, providing real-time data on system performance and health. This remote monitoring capability enables dealers to detect issues early, schedule maintenance proactively, and ensure optimal operation. “InteliSense Technology uses cutting-edge sensors to communicate with the system via the thermostat, storing data in the privacy-protected Carrier cloud, and delivering it remotely to Carrier experts,” says Arch. “This allows for accurate troubleshooting and maintenance, reducing downtime and improving service efficiency.” These advancements help improve customer satisfaction and reduce downtime, he says. Advanced defrost technology The precise control provided by this technology enhances the reliability and efficiency of the heat pump Carrier heat pump systems also feature advanced defrost technology that monitors the outdoor coil for the presence of frost. The system uses sensors to detect frost buildup and adjusts the compressor speed to initiate defrosting. Once the frost is melted and drained, the defrost mode concludes automatically. This functionality ensures timely and efficient defrosting, thus minimizing energy waste and maintaining optimal system performance. The precise control provided by this technology enhances the reliability and efficiency of the heat pump. Step in reducing the GWP of heat pumps The transition to R-454B refrigerant, known commercially as Puron Advance™, has been a significant step in reducing the global warming potential (GWP) of heat pumps. Carrier has worked diligently to ease the transition for the dealer/installer community by providing comprehensive training and resources since 2023, says Arch. “The new refrigerant is a near drop-in replacement for R-410A, with similar operating pressures and temperatures, making the transition smoother for technicians,” he adds. Carrier has also conducted extensive field trials and developed detailed guidelines to ensure that dealers and installers are well-prepared for the changeover, minimizing disruption and ensuring a seamless transition.

In facilities with high volumes of foot traffic, the constant opening and closing of doors not only lets in chilly air but can cause heating problems for the entire building. Cold drafts bring the temperatures down, so while main rooms benefit from the warmth of the building’s primary heating system, many other areas are left to deal with the arctic side effects. Vestibules, lobbies, entrance ways, and hallways are frequently populated, so it’s imperative that facilities hunker down and counteract the cold drafts left behind by those entering and leaving buildings.  Ideal for entryways Facilities should consider fan-forced wall heaters that provide continuous comfort To help neutralize these blustery winds, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Such units are ideal for entryways and other spaces where short bursts of heat are needed – providing a tremendous advantage over gentle heating sources that may not be powerful enough to provide the desired amount of warmth. Opt for electric ceiling heaters However, if wall and floor space is minimal, facilities can instead opt for electric ceiling heaters. Mounted flat or recessed to the ceiling, these heaters are ideal not only for entryways but also in conference rooms, waiting areas, bathrooms and lobbies. No matter the case, both products move heated air with a fan to quickly heat the room from the wall or ceiling. Once the heater turns on, air is moved over a heating element and circulated into the space, making certain that residents are met with warmth and comfort from the time they enter the building until they leave.  Specialized Performance Specialized heating units are designed to stop drafts in their tracks before they spread Whether it’s through vents, unsealed windows or cracks and crevices in the building’s foundation, cold air will creep into facilities any way it can. This cool air can make indoor temperatures uncomfortable for occupants and reduce the overall heating efficiency of the facility. Specialized heating units are designed to stop drafts in their tracks before they spread throughout a building.  Integrated thermostats or BMS connections Fan-forced wall and ceiling heaters with an automatic delay feature eliminate cold drafts on start-up and discharge residual heat from the heater body during shut down, helping attack drafts at their source, making the best use of available heat and prolonging the life of the heater. To maintain desirable comfort levels, facilities should consider fan-forced wall or ceiling heaters equipped with integrated thermostats or BMS connections for easy adjustment of room temperatures.  Commercial fan-forced wall heaters Adjustable thermostat feature allows facilities to alter their heating output needs A hotel’s vestibule, for example, may experience high amounts of foot traffic during check-in and check-out hours. Because less people are coming and going outside of these times, the adjustable thermostat feature allows facilities to alter their heating output needs to ensure heat is not misused and temperatures remain comfortable.  For commercial fan-forced wall heaters with striking designs and contemporary looks, Berko® and QMark® offer units to match any room’s décor while supplying an appropriate amount of warmth no matter the time of year.  Safety First Safety and style go hand-in-hand. While selecting a heater that fits a building’s aesthetic is important, opting for a high-quality product that protects against common safety risks should be a top-of-mind priority. Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for added safety during maintenance. Tamper-proof plugs for thermostat holes prevent unwanted changes to the temperature and keep children and pets from getting into places they shouldn’t.  Thermal overheat protectors Heaters that include permanently lubricated and enclosed fan motors are shown to have longer lives All fan-forced units also come with thermal overheat protectors that disconnect power in the event of accidental dust or debris blockages to mitigate risk of injury. Additionally, heaters that include permanently lubricated and enclosed fan motors are shown to have longer lives, require less maintenance and gently administer heat throughout a space. Keep in mind that some heaters are noisier than others, so make sure to choose one powerful enough to negate drafts but quiet enough to prevent disturbances from interrupting daily activities.  Maintaining Warmth and Comfort Drafts bring cold air and a lasting chill into heated spaces every time a door opens, especially during the colder months. To offset the frigidness, consider installing a fan-forced wall or ceiling heater to regain suitable levels of warmth and comfort for all building occupants. Berko and QMark’s commercial fan-forced wall and ceiling heaters provide the strongest, safest sources of heat for those chilly spaces.

Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change.  About A-Gas  A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future.   Challenge  HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact.   Solution  To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”

With 53 men on the Jacksonville Jaguars roster, practicing 5 to 6 days per week for 10 to 12 hours a day, the demand for hot water must be enormous. As the choice for the team’s practice facility’s hot water storage and water heating capabilities, we happen to have the deets. How about 1,880 gallons of storage capacity and 2,400,000 btu/hr heating the water?  Miller Electric Center The Miller Electric Center is a new state-of-the-art practice facility in downtown Jacksonville that serves as the Jaguars’ football operations headquarters.
