The company continues to help installers manage ongoing refrigerant change. The valves are just two of an extended well-known refrigeration portfolio of Danfoss products to be qualified for the A2L-classified refrigerants, in response to demand from customers who want to use ultra-low GWP alternatives to R404A and R134a. Danfoss has created new, dedicated versions of the popular design, an industry staple since the T2’s launch in 1966. As with all mechanical valves, each model is optimized for the characteristics of the refrigerant in question. Safe and easy for installers Like most ultra-low GWP alternatives, R454C, R455A and R1234yf are mildly flammable The process is particularly thorough because, like most ultra-low GWP alternatives, R454C, R455A and R1234yf are mildly flammable—carrying the ASHRAE classification A2L—and therefore subject to additional safety requirements. Every component undergoes carefully planned testing, and is modified as necessary to make it safe and easy for installers to meet key regulations such as the Pressure Equipment Directive (PED). Precautions include: Thorough compatibility testing for internal polymers and raw materials in contact with refrigerant and oil Bulb charge optimization to match for the different pressures and temperatures of the refrigerants A2L-ultra-low GWP refrigerants “For several years, HVACR professionals have been on quite a journey with new refrigerants, and the T2/TE2 expansion valves have been adapting to market needs,” says Danfoss Product Director for Expansion Ejner Kobbero. “Now, with A2L-ultra-low GWP refrigerants growing in popularity, it feels like that time of transition may finally be coming to an end in some regions and countries.” “Whatever the future holds, Danfoss will continue to use our expertise to support our customers with the widest possible range of components, that are safe and fully qualified for all the viable refrigerant options.”

As one of the key industries encouraged and supported by the Chinese government, Biomass CHP, beneficial for both the environment and economy, can alleviate energy shortage, as well as improve the environment and employment to a certain extent. Biomass boilers and steam turbine units installed Dongfang Paper will construct two 75 t/h biomass boilers and two 4.5 MW back-pressure type steam turbine units According to the plan of the Biomass CHP project, Dongfang Paper expects to construct two 75 t/h biomass boilers and two 4.5 MW back-pressure type steam turbine units, as well as auxiliary production facilities. The whole project is expected to be finished at the end of 2021. With successful operation, the project is expected to generate annual electricity output of 56.45 million kw/h, from which the Company expects to generate revenue of RMB42.9 million per year based on the biomass electricity price of RMB0.76/kwh guided by the National Development and Reform Commission. Generation of large-scale heating steam The project is also expected to generate annual heating steam of 521,100 tons, from which the company expects to generate revenue of RMB114.64 million per year based on the heating steam's current market price of RMB220 per ton. Mr. Zhenyong Liu, Chief Executive Officer (CEO) and Chairman at IT Tech Packaging, Inc. commented, "The biomass CHP project is expected to not only provide adequate power and gas supply to the Company's tissue paper production located in Wei County Industrial Park, but also provide bio gas for production of enterprises in the Wei County Industrial Park, as well as heating steam and electricity supply for nearby residents." He adds, “The construction and operation of the Biomass CHP is expected to enable us to expand to the renewable energy field and continue to diversify our offerings of products, which we believe will bring more stable revenue streams in the future."
There is a demonstratable link between humidity and the infectivity and longevity of a variety of viruses, such as influenza and coronaviruses, according to a new whitepaper by Munters, a globally renowned company in energy-efficient and sustainable air treatment solutions. Titled ‘How Humidity Control Can Reduce Viral Infectivity and Longevity’, the scientific report addresses how it is possible to reduce the transmission and longevity of harmful viruses by controlling indoor Relative Humidity (RH) levels. ‘How Humidity Control Can Reduce Viral Infectivity’ The paper is based on gathered research, including studies on the efficiency of respiratory droplet transmission at humidity and temperature, virus survival and transmission at absolute humidity levels, and the effect of environmental parameters on the survival of airborne infectious agents. Among the most notable and timely findings, the research demonstrates that at RH levels between 40 and 50%, many types of common and harmful viruses such as influenza and coronaviruses are rendered inert much more quickly than at RH levels of less than 20%. “Viruses that cause respiratory illnesses are often transmitted by viral particles through coughing, sneezing, talking and breathing,” said Martin Ginty, Global Pharmaceutical Industry Manager for Munters. Controlling indoor Relative Humidity (RH) levels By effectively controlling indoor climates, it is possible to limit the transmission of harmful viruses" Martin adds, “Research referenced in our whitepaper suggests that maintaining an indoor RH% level between 40 and 50% yields the maximum protective effect from both aerosolized and settled virus particles and that by maintaining these levels, it is possible to contribute to a healthier, safer environment.” “This evidence is particularly relevant in locations where winter tends to consist of low outdoor temperatures and low indoor humidity, as these conditions offer a favorable environment for viral transmission,” added Ginty. Martin further said, “By effectively controlling indoor climates in these locations, it is possible to limit the transmission of harmful viruses.” Maintaining target RH levels Maintaining target RH levels can be accomplished using humidity control solutions which facilitate precise RH control for indoor environments. Furthermore, the whitepaper concludes that humidity control is always useful, but particularly during a typical ‘flu season,’ where outdoor temperatures and absolute humidity tend to be lower.
HVAC systems are the most common home repair, representing 19 percent of service incidents facing homeowners. More than half of homeowners (53%) have faced a home repair emergency of some kind in the past 12 months. Furthermore, about a third of homeowners have US$ 500 or less set aside to pay for emergency home repairs, with some 17 percent having no money at all set aside for emergency home repair work. 10th Edition of the Biannual State of the Home Survey These are among the results of the 10th Edition of the Biannual State of the Home Survey conducted by The Harris Poll on behalf of HomeServe USA Corp., a provider of home repair solutions in the U.S. and Canada. The survey carried out covered 2,026 U.S. adults (of which 1,454 are US homeowners) was conducted during the early days of the COVID-19 pandemic lockdown. HomeServe’s real-time repair data shows that customers are continuing to require urgent repair help during the COVID-19 pandemic period. Greater strain on home infrastructure and HVAC systems More Americans are putting extra strain on their homes’ infrastructure and major systems More Americans are putting extra strain on their homes’ infrastructure and major systems. As parents are spending more time working from home, and the children are in home schools, the shortcomings of existing systems are becoming more obvious, especially as the summer temperatures rise. In the current uncertain times, comfort is more of a need than a luxury. Concerns about air quality in the wake of the COVID-19 pandemic, which is occurring at the height of the allergy season, are also driving new business for HVAC technicians. Technicians using personal protective gear at homes Service technicians are using proper social distancing protocols and personal protective gear (PPE) while performing maintenance and service tasks at consumers’ homes. Consumers want to know what companies are doing differently to protect their customers during the pandemic. At the very least, installers should keep contact to a minimum and meet Centers for Disease Control and Prevention (CDC) and state and local requirements to contain the spread of the coronavirus. Following social distancing protocols in repair works “We’re wearing gloves, washing our hands between calls, wearing masks, and we have sanitizers and soaps in our cars, making sure we are maintaining safety,” said Michael Concannon, Repair Technician for Bell Brothers, located in Sacramento, California, USA. There is also an opportunity for HVAC companies to provide expert advice on subjects that customers are asking about now, such as indoor air quality. In the midst of economic uncertainty, routine maintenance can provide greater peace of mind, as well as extend the life of equipment. Consumers to foot bill for home repair work According to the HomeServe survey, many homeowners do not know it is their responsibility to pay for home repairs According to the HomeServe survey, many homeowners, especially younger ones, do not understand that it is their responsibility to pay for home repairs. Many mistakenly believe repairs will be covered by a city/municipality, a water utility, or a homeowner’s insurance. “The findings of the latest survey clearly show that homeowners, especially younger ones, are unaware of their responsibility when it comes to common home repairs,” said John Kitzie, HomeServe USA Chief Executive Officer (CEO). Smart financial planning tools John adds, “HomeServe seeks to educate homeowners and to provide them with smart financial planning tools so they are prepared when an inevitable home emergency strikes.” HomeServe USA serves more than 4.4 million customers across the U.S. and Canada under the HomeServe, Home Emergency Insurance Solutions, Service Line Warranties of America (SLWA) and Service Line Warranties of Canada (SLWC).
The American Innovation and Manufacturing (AIM) Act of 2019 would provide an orderly national framework to guide replacement of hydrofluorocarbons (HFCs) over the next several years in the United States, with newer refrigerants that have less negative impact on the environment. HFCs are potent greenhouse gases with very high global warming potential. The future of the HVAC industry is tied to the manufacture of next-generation refrigerants and their adoption. Versions of the AIM Act – Senate bill S.2754 and House bill H.R.5544 – are currently in the Senate Environment and Public Works and the House Energy and Commerce committees. The global market is moving away from the use of HFC refrigerants, given that the Kigali Amendment to the Montreal Protocol requires their phaseout; however, the United States has not ratified the Kigali Amendment. Over the next 15 years, the AIM Act would phase down HFC to a low of 15% of current production and consumption levels. In addition, aftermarket supplies from recovery, recycling and reclaiming would ensure adequate availability of the refrigerants for use in legacy systems and in applications for which substitutes are not available. Economic Stimulus For The U.S. HVACR Industry The Air-Conditioning, Heating and Refrigeration Institute (AHRI) contends passing the act would “serve as a potent form of economic stimulus for the U.S. HVACR industry,” in addition to providing clarity on the regulatory landscape. The AIM Act would create new manufacturing jobs in the United States, spur HVACR investment in the U.S. economy, and ensure the continued safety and training of licensed HVACR professionals, experts say. Over the next 15 years, the AIM Act would phase down HFC to a low of 15% of current production and consumption levels The Air Conditioning Contractors of America (ACCA) support the federal approach to an HFC phasedown as preferable to a state-by-state approach, urging Congress to include preemption language in the AIM Act that would require states to follow a federal HFC phasedown schedule for the residential HVACR market. Addressing Safety Concerns Safety concerns arise with the introduction of A2L mildly flammable refrigerants as part of the next phase down of HFCs. ACCA says a unified approach across the United States will ensure the introduction of A2L refrigerants is done safely. Commercial and industrial HVAC markets have been using flammable refrigerants for years; however, building codes and safety standards in the residential market do not currently allow their use. ACCA also urges inclusion of language in the AIM Act to strengthen EPA certification programs and restrict the sale of HVACR systems and refrigerants to only trained and certified individuals. “If Congress does not provide the EPA the authority to regulate and implement an HFC phasedown, then the EPA may not be able to implement training and certification programs or restrict the sale of dangerous products to unqualified people,” according to testimony the ACCA submitted to the U.S. Senate Environment and Public Works Committee. Ending "Dumping" The future of the HVAC industry is tied to the manufacture of next-generation refrigerants The AIM Act would also seek to end the practice of “dumping,” in which foreign manufacturers export inferior products to the United States that are priced below the cost of manufacture. The AIM Act would restrict the import of HFCs as part of the production and consumption phasedown. However, the non-profit Competitive Enterprise Institute (CSI) rejects the need for the AIM Act. “The free market provides the best policy answer,” writes Ben Lieberman, CEI Senior Fellow. “Let the new refrigerants and equipment compete with the current ones, rather than favoring one over the other [through legislation].”
The need to achieve energy efficiency and improve performance propels a lot of business in the HVAC industry. When installing systems, building owners often strive to comply with the latest voluntary standards. However, some cities are taking the lead to make building performance standards mandatory, thus providing additional incentive for customers to invest in new, more efficient and climate-friendly HVAC technologies. Building Energy Performance Standard NYC has deployed its Carbon Mobilization Act, which will cut six million tons of CO2 annually by 2020 Washington D.C. adopted the first Building Energy Performance Standard, which will reduce energy use in buildings by more than 20%, thereby lowering carbon dioxide emissions by a million tons annually. The first compliance cycle in 2021 will cover buildings of 50,000 square feet, and the threshold will drop over the next few years to include smaller buildings. New York has deployed its Carbon Mobilization Act, which will cut six million tons of carbon dioxide annually by 2020, thus preventing 43 premature deaths and 107 emergency room visits every year, and creating at least 26,700 green jobs, according to New York City officials. Clean Buildings Act Washington State projects that its 2019 legislative package, the Clean Buildings Act, will reduce annual carbon dioxide emissions by 14 million tons by 2035. “Jurisdictions are looking to Building Performance Standards because they are the most powerful and direct tool for driving improved performance in existing buildings,” said Cliff Majersik, Executive Director of the Institute for Market Transformation (IMT), a non-profit organization that promotes energy efficiency, green building and environmental protection. Fighting climate change IMT is promoting the use of Building Performance Standards (BPS) and working with cities to explore, develop and execute the policies. Fighting climate change at the local level means taking serious steps to reduce carbon emissions generated by buildings, which include shifting to mandatory policies. A powerful new tool in the fight against climate change is the mandatory Building Energy Performance Standard A powerful new tool in the fight against climate change is the mandatory Building Energy Performance Standard, which requires building owners to meet performance targets by actively improving the energy performance of their buildings over time. By setting long-term targets, a BPS provides the commercial real estate market with the certainty it needs to make confident investments in properties over time. Energy-efficient HVAC systems in buildings A BPS also provides flexibility for building owners to use whatever technologies, including HVAC products and systems, along with whatever operational strategies they decide are most effective and economical to meet the target. Leveraging technology advancements in the HVAC industry can contribute positively to a building owner’s ability to meet the target. According to IMT, benefits of Building Performance Standards include: Carbon reductions, especially in existing buildings. Job creation, including large opportunities for the expansion of private firms offering architectural, engineering, construction, equipment sales, and installation services (including HVAC). Economic and social benefits, including healthier air quality for occupants, lower carbon emissions, and lower utility bills that benefit the bottom line of local companies. American Cities Climate Challenge IMT is driving the BPS initiative in partnership with the American Cities Climate Challenge, sponsored by Bloomberg Philanthropies, which is an opportunity for 25 ambitious cities to significantly deepen and accelerate their efforts to tackle climate change and promote a sustainable future for their residents. Originally open to 20 American cities, the program was expanded to 25 cities due to the strength of the applications received. The goal of the American Cities Climate Challenge is to enable mayors and their partners to scale and implement proven climate solutions and innovations that will help grow the economy, protect public health and improve the quality of life for citizens.
Viessmann heating, cooling and ventilation products have been selected by PERI GmbH, one of the suppliers of formwork and scaffolding systems, as well as civil engineering solutions, for Germany’s first 3D-printed house. Located in the North Rhine-Westphalian town of Beckum, the two-storey, 160 m² single-family home is currently under construction. The 3D printing process has already been applied to the walls of the house. A nozzle applies special concrete in layers. The print head moves over three axes on a fixed frame and is controlled by just two people. It takes just five minutes to print one square meter of a double-shelled wall. Energy efficiency rating This innovative technology saves more than time compared to conventional construction methods; it also significantly reduces resources and allows for greater freedom in building design. When completed, the first home will be heated and cooled by a high-efficiency Vitocal 200-S air/water heat pump and ventilated by the Vitovent 300-W ventilation system. The temperature will be perfectly regulated all year round. The new Vitoset heat pump-hybrid cylinder WPU 300/100L will be installed as a heating buffer and DHW cylinder The heat pump is highly efficient with a COP (coefficient of performance) of up to 5.0 (EN 14511 at A7/W35°C) and has an energy efficiency rating of A++. The new Vitoset heat pump-hybrid cylinder WPU 300/100L will be installed as a heating buffer and DHW cylinder. The hybrid cylinder solution saves a lot of space since it consists of one 300-liter enamel DHW cylinder and a 100-liter buffer cylinder. The cylinder is delivered in one piece and is completely insulated. Additional residential projects Fresh, clean, and especially germ-free ambient air is more important than ever in times of COVID-19, and so the Vitovent 300-W central home ventilation system will also be installed in Germany’s first 3D-printed house. This quiet ventilation system is particularly quiet and compact and recovers up to 92 per cent of the heat from extracted air during the cold weather, saving heating costs. In combination with the Vitocal 200-S heat pump, the ventilation can be conveniently controlled using the free ViCare app on a smartphone. PERI GmbH expects 3D printing to gain in importance in the next few years, and additional residential projects are already in preparation.
As Albert Einstein once said, “We can't solve problems by using the same kind of thinking we used when we created them.” That wisdom has been put into practice in the form of a smarter approach in the way modular schools can be built and used. Pre-fabricated, modular classroom In 2006, the Montgomery County Public Schools in Maryland, in partnership with the Council for Educational Facility Planners (CEFPI), held a national design competition, The Portable Classroom Design Challenge, to create a pre-fabricated, modular classroom unit that was environmentally sustainable, or green. This competition led to eventual development and installation of one of the most uniquely created modular spaces ever conceived, indeed the award winner of the design competition. Triumph Modular of Littleton, Massachusetts, in partnership with ARC/Architectural Resources Cambridge and builder NRB Inc., won the design challenge because of their revolutionary, new modular classroom. Relocatable Green Modular Classroom Relocatable Green Modular Classroom comes designed with many LEED-focused design elements Aptly named the Relocatable Green Modular Classroom, it's also the first modular classroom to be designed with many LEED-focused design elements. “Our goal was to create a high-quality, portable classroom that was green, one with environmentally conscious materials used in its design and operation. The design was smart in the way that it used resources and provided heat, light, unsurpassed acoustics and air quality within the space,” said Cliff Cort, Founder of Triumph Modular. In fact, it’s estimated that the Relocatable Green Modular Classroom performs 56% better, in terms of overall energy costs, than similar, older style modular units that often use almost three times as much of energy as a permanent school building. Wall-mounted heating and cooling equipment Thirty years ago, Bard Manufacturing Co. Ltd began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s products offer a combination of quiet operation, patented ventilation packages, unsurpassed quality and dependability that make them the #1 choice of many school officials. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. Self-programming energy monitors and green refrigerants With features like self-programming energy monitors, unsurpassed energy efficiency, green refrigerants and the lowest acoustic profile on the market, Bard delivers products that provide tangible solutions for modern school facilities. Already impressed from their previous working experience with Bard, Triumph Modular wanted to incorporate the Quiet Climate 2 into their green modular design. “Building green is good for the environment, good for the wallet and good for the occupants of the building,” said Cliff Cort, adding, “And Bard’s HVAC unit is a big factor in why the Relocatable Green Modular Classroom performs as well as it does.” Green modular design Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes to its high energy efficiency According to an independent third party analysis, the green modular design provides a 68% reduction in heating energy and a 49% reduction in cooling energy, most of which can be attributed to Bard Quiet Climate 2. An efficiently designed HVAC system is perhaps the single largest building component that can influence a building’s sustainability. Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes significantly to its high energy efficiency and quiet, almost undetectable acoustic profile (37 bBHL) within the classroom. Quiet-Climate 2 heat pump Bard’s Quiet-Climate 2 heat pump is the most innovative wall-mount HVAC equipment ever made. Designed specifically to provide superior energy efficiency and quiet operation in classrooms, the Quiet Climate 2 uses green refrigerants and provides operating sound levels that are 20 to 35 times quieter than a standard wall-mounted heat pump. Bard’s Quiet Climate 2 can provide the following features: Higher energy efficiency and greater comfort through step-capacity technology Unmatched acoustical performance Sound levels vary with applications and construction techniques, but integrated operating sound levels as low as 35 dbA have been achieved when combined with Bard Quiet-Climate acoustical accessories Improved ventilation and Enhanced IAQ Continuous blower operation – without noise – keeping fresh air constantly in the classroom Optional UV lighting which keeps the coils free of bacteria and mold Enhanced filtration capabilities A one-piece factory unit designed for fast installation and easy servicing Additional sound curbing accessories including, an isolation curb and return air and supply air plenums The Carroll School Serving over 75 communities around Lincoln, Massachusetts, The Carroll School was founded in part by Dr. Edwin Cole who wanted to provide a special school for children with language-based learning challenges. The Carroll School supports nearly 300 students, in grades 1 – 8, with a 3.4 student to teacher ratio using multisensory and individualized teaching methods for specific learning needs. Progressive by nature, The Carroll School’s thriving community brings children together in an environment that values their differences and remediates their learning difficulties. “Cliff Cort, a Lincoln resident and friend of the school, approached us with the idea to replace one of our existing modular building with the green modular design,” said Margaret Gebhard, Director of Finance and Operations at The Carroll School, adding “Our existing modular space was not a popular one with either faculty or students due to its poor lighting, sound characteristics and overall appearance.” Occupancy sensors and vestibule The classroom incorporates many unique green components, such as formaldehyde-free, low VOC paints Things changed when teachers, students and administrative personnel moved into the Relocatable Green Modular Classroom for the first time. The classroom incorporates many unique green components, including formaldehyde-free, low VOC paints and coatings that reduce off-gassing, occupancy sensors that conserve energy by turning the lights off, when people come and go, a vestibule that safeguards the inside from inclement weather while buffering outside noise and helps retain heating and controlling levels for its green and virtually silent HVAC system – the Quiet Climate 2. Enhancing schools’ energy efficiency Margaret adds, “The Relocatable Green Modular Classroom is truly amazing and smart to incorporate into any schools modular planning, we’re quickly approaching our original 3 year leasing agreement with Triumph and I see us keeping the Relocatable Green Modular Classroom around for many more years to come.” She further stated, “It has the best lighting, best HVAC system, and is the most energy-efficient building on our campus, which is why it’s also the most coveted space on our campus. Now we can not only say our kids here are special but now they have a truly special and smart environment in which to learn.”
Blackheath High School, an independent day school for girls and part of the Girls’ Day School Trust (GDST) network, recently invested £18 million to provide new state of the art facilities including a new library and resource centre, and AET Flexible Space supplied an underfloor air conditioning system to provide comfort cooling for students in the new learning zone. The project involved the design and construction of a three storey new build, aesthetically designed to blend with the existing Victorian structure. The library and resource center are located in the lower ground floor, sunk beneath the existing site and the new courtyard area. Air conditioned zone Underfloor air conditioning makes use of the plenum beneath a raised access floor Due to the underground location of the resource centre, air conditioning was required for this area, and an underfloor air conditioning system was specified by consultant Hilson Moran so that the ceiling space, featuring the unique pyramidal skylights, could be left exposed. Underfloor air conditioning makes use of the plenum beneath a raised access floor to distribute conditioned air. At Blackheath High School, a single CAM-V33 Direct Expansion downflow unit serves the air conditioned zone, and the conditioned air is supplied into the space by 14 TU4 Fantiles. The CAM-V receives spent air back for re-conditioning via high level transfer grilles. A major challenge with this project was the 900mm high underfloor void within the main resource area, requiring special modification to the CAM baseframe and raised floor substructure. The new state of the art facility reached practical completion over the summer of 2018 and was ready for students to use in September at the start of the new school year.
The new Adidas LDN flagship outlet in London, which opened late October 2019, has been specifically designed to enhance the retail experience. As the brand’s most technologically-advanced store worldwide, it required a ventilation system that would effectively deliver a fresh air supply across the four-storey, 27,000 sq. ft, site, in the most energy efficient way possible. Adidas is one of the most well-known sports brands in the world, and so it’s to be expected that when it launched its new store on Oxford Street, London, it would be no ordinary shopping experience. Digitally-Savvy innovations The store features over 100 digital touch points that are all powered by green energy The store features some of the most digitally-savvy innovations in retail, such as interactive mirrors in changing rooms that allow shoppers to order different sizes direct from the stockroom, a ‘Bring It To Me’ feature using in-store geolocation tracking to allow customers to shop without queueing, and a MakerLab where clothes can be customized with personalized designs. However, with additional energy usage comes additional heat sources, and therefore the size and volume of air required to keep the building and shoppers cool needed to be carefully calculated. The store features over 100 digital touch points that are all powered by green energy. While incorporating these interactive elements into the design of the store would, undoubtably, help to revolutionize the high street, subcontractor, PCB Technical Services, also recognized that they would increase energy usage and would therefore result in additional heat loads. Enhanced technical support With this in mind, a ventilation system that would be able to meet a consistently high demand at all times was required. What’s more, a quick turnaround was essential to ensure the unit would be installed and delivered within time and budget. After an initial supplier interview and factory review, Ricardo Hudson, Senior Technical Project Manager at PCB Technical Services, was given the confidence to opt for a bespoke Air Design unit from Elta Fans. This was thanks to the company’s enhanced technical support and understanding of the project, as well as its ability to meet the tight delivery date. Elta Fans uses in-house Air Design technical engineers who utilize specialist software to tailor the unit especially for the customer’s exact needs; considering performance, efficiency, noise, and, most importantly, the latest regulations and any site restrictions. Air Design ventilation unit The Air Design ventilation unit supplied by Elta Fans was custom-made, ensuring it was able to effectively ventilate Providing fresh air to a store as big as this one is essential if customers are to feel comfortable while browsing, but it is also crucial that adidas adheres to the most up-to-date energy standards and legislation. The Air Design ventilation unit supplied by Elta Fans was custom-made, ensuring it was able to effectively ventilate according to the unique size and layout (across four floors) of the store. The specialized solution chosen, the fully-configured PURA+ Air Handling Unit (AHU), would be mounted on the roof to maximize space on site. The challenge of transporting the AHU into position was exacerbated by the high-profile nature of the location. PCB Technical Services was reluctant to disturb the busy street, particularly given the strict local regulations that had to be upheld. Improved ease of installation A great deal of planning was required to fit the unit as PCB had to work within a limited timeframe, gain the relevant planning permission, and eliminate as many risks as possible to nearby occupants and shoppers. As a result, the team was required to arrange a specific timeslot for delivery to site. As the Air Design unit was manufactured offsite, it was able to be lifted into place by crane, minimizing road closure time, and ultimately disruption. This also improved ease of installation as it was delivered in two parts and could be easily bolted together once in place. Now installed and operational, the AHU delivers a consistent fresh air supply into the building by removing polluted air and replacing it with clean air, at the most efficient temperature. Balancing indoor air quality This allows the store manager to balance indoor air quality (IAQ) and energy efficiency Building Management System (BMS) controls enable the store manager to ensure the ventilation system is working as it should in tandem with other products. This is essential as it is not just the store itself that needs to be kept cool, but also the data center, which generates a significant amount of heat from the servers. Controls will essentially determine how a ventilation unit runs, whether that’s scheduling airflow, linking to a BMS, permitting fault signals and alarms, or communicating that filters need changing. Ultimately, this allows the store manager to balance indoor air quality (IAQ) and energy efficiency, and also effectively manage operating costs. Evolving ventilation demand Ricardo said: “The unique challenges of the project were amplified with the introduction of a series of in-store digital screens. This meant that more heat was being generated within the structure, thus increasing the levels of ventilation required.” “It also necessitated wholesale changes to the ductwork system, in order to increase the velocity and retain ambient temperatures. Owing to its reputation in the industry and having already completed several successful projects together, Elta Fans was the standout choice to provide us with an AHU capable of meeting this evolving ventilation demand.” The bespoke PURA+ that we ultimately installed was ideal for meeting the velocity" “The bespoke PURA+ that we ultimately installed was ideal for meeting the velocity and air volume required for the store’s footprint. Plus, it was able to integrate with the BMS, enabling us to manage the significant amount of power throughout the building.” Quickly identify ventilation requirements Melissa Goodman, Technical Sales Manager at Elta Fans, said: “The challenge of providing consistent air flow across the site’s four floors was underpinned by the tight time constraints. It presented the Air Design engineers with an exciting opportunity to produce a bespoke PURA+ that was both straightforward to install, but also robust and powerful enough to perform as required.” Ricardo concluded: “Finding a bespoke solution in a short amount of time is difficult, and this project highlights the importance of choosing a brand that offers consistency, even in its customized products. The adidas project was a perfect example of Elta Fans’ ability to quickly identify ventilation requirements, and the PURA+ unit provided by Air Design highlights its precise approach to tackling air movement problems.”
Two new Burnham model MPC™ high efficiency commercial boilers were recently installed by The Witmer Company of New Holland, PA in the historic ‘High Point’ Mansion located in Hershey, PA. The Model MPC boilers will provide space heating for the 22-room Mansion which was built in 1908 as the home of Milton and Catherine Hershey. Mr. Hershey was the founder of the Hershey Chocolate Company, now known as The Hershey Company. Today, ‘High Point’ Mansion serves as the headquarters location for the Hershey Trust Company which, among other things, oversees the continued philanthropic efforts that were founded by Milton Hershey. Exceptional heat transfer Two, five-section model MPC boilers were selected to provide heat for the building through a combination of 5 air handlers, 52 fan coils and commercial finned tube radiation. The MPC’s are well suited for the job with their unique 3-pass flue design and Return Water Mixing Tube, which translates into exceptional heat transfer as well as the ability to accept return water temperatures as low as 80°F. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch The MPC’s are manufactured in nearby Lancaster, PA using BC25-HSi cast iron sections, which contain high levels of silicon for exceptional flexibility and heat transfer capabilities. Even at start-up a big difference could be noticed – the boiler room temperature had dropped 30-degrees from the previous boilers. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch, and the boiler room at the Hershey Mansion is now a much more comfortable place to work. Heat distribution systems Heat transfer and high efficiency is only part of the equation in this new installation, with a variety of heat distribution systems and controls the MPC’s needed to integrate with an advanced control system. The power burners were ordered with the powerful new Burnham SBC™ – or Sage Boiler Control, which made the control portion of this job simple for the Witmer crew. The SBC’s control many of the boiler room functions such as outdoor reset, multiple boiler modulation, lead-lag boiler rotation, combustion air louvers, and pump controls, all without the need for additional control systems. And the SBC’s tie right into the existing building management system so the whole system works together to deliver comfortable, efficient heat throughout the beautiful historic Hershey Mansion.
Like many first responder organizations, the COVID-19 pandemic has led the Louisville Metro Police Department (LMPD) to implement several new policies and procedures to help keep officers safe so that they can continue their essential job of protecting the community. As a result, officers at the department's Firearms Training Center have been limiting trips to the grocery store as well as limiting access to the facility by non-essential personnel to curb any unnecessary exposure. Through GEA4Heroes, GE Appliances provided the center with a new refrigerator to keep foods safe for on-duty officers. First responders and healthcare workers Additionally, GEA supplied a new washer and dryer set to allow officers to clean potentially contaminated materials. "It's tough and uncertain times, and we realize that as far as essential job duties and employees is that we both fit into the category," LMPD Ofc. Matt Gelhausen said. "And we're both working together to be able to fulfill our job to be able to continue to serve this community, and in turn, as GE Appliances does serving our nation." GE Appliances launched the GEA4Heroes program in April with United Way Worldwide. A significant portion of appliances produced during the first two weeks of April are being donated to first responders and healthcare workers across the country.
