The Volvo Group has improved its performance by more than 50% since joining the challenge in 2012.
Hyundai Motor Company and Kia Motors Corporation have revealed new details of their innovative heat pump system, deployed in Hyundai and Kia's global electric vehicle (EV) line-up to maximize their all-electric driving range in low temperatures. Hyundai and Kia's heat pumps are a renowned heat management innovation that maximizes the distance that Hyundai and Kia EVs can travel on a single charge, scavenging waste heat to warm the cabin. It enables EV drivers to heat their car's cabin in cold weather without significantly impacting electric driving range, unlike other EVs. The technology was first introduced in 2014 on the first-generation Kia Soul EV. Comprising a compressor, evaporator and condenser, the heat pump captured waste heat given off by the vehicle's electrical components, recycling this energy to heat the cabin more efficiently. The technology meant the Soul EV's 180 km electric range was protected in cold weather driving conditions. real-range validation test The industry renowned heat pump system has now been developed further for new EVs from Hyundai and Kia. The new system scavenges waste heat from an increased number of sources for optimum cold-weather EV range. These innovations mean that Hyundai and Kia EVs offer more consistent range in temperatures where other EVs start to see a significant decline in the distance possible from a single charge. The test monitored the performance deviation of each vehicle in cold conditions compared to quoted figures Equipped with the latest heat pump technology, the Kona Electric proved this in a recent test in Norway, the most advanced EV market in the world. The Norwegian Automotive Federation (NAF) recently compared 20 EVs in cold and warm weather conditions to identify models with the most consistent driving range and charging performance. The test monitored the performance deviation of each vehicle in cold conditions compared to quoted manufacturer figures. EV cabin heating The Kona Electric took first place, travelling 405km in the cold – compared to the 449km quoted under WLTP combined cycle testing conditions (23°C / 73°F). In severe cold weather, the Kona Electric offered 91 percent of its WLTP combined cycle range, deviating just 9 percent from its claimed all-electric driving range. Hyundai and Kia's heat pump technology made its debut six years ago on the first-generation Kia Soul EV. Since then, the industry renowned heat pump technology has been developed further for new EVs from Hyundai and Kia. It now harvests significantly more energy by recycling additional waste heat not only from power electrics (PE) modules (such as drive motors, on-board chargers, and inverters), but also from the battery pack and slow charger. The system uses the heat generated by these components to vaporize refrigerant from liquid to gas form. minimize battery power consumption High-pressure gas is discharged from the compressor and forced into a condenser to be converted back into a liquid. This process generates additional heat energy that is recovered by the heat pump and used to warm the cabin. This captured energy improves the efficiency of the HVAC (heating, ventilation and air conditioning) system, recycling it to more efficiently heat up the cabin and minimize battery power consumption. By reducing the load on the battery, the heat pump cuts energy consumption from the HVAC system By reducing the load on the battery, the heat pump cuts energy consumption from the HVAC system, maximizing the available electric driving range of the car. Hyundai and Kia continue to develop their heat pump technology to yield even greater improvements in energy capture and efficiency. The system has been gradually refined since its 2014 introduction through extreme cold weather testing in Northern Sweden, where temperatures can get as low as -35°C (-31°F) in the winter. Battery pack heat management By testing in extreme cold temperatures, research engineers have identified additional ways to recycle as much waste heat as possible to increase the efficiency of the heat pump system. Testing the technology in these conditions ensures the heat pump is capable of operating in even the coldest environments. The heat pump is one of a number of innovations found in Hyundai and Kia's current generation of EVs, with heat management also used to realize major improvements in EV battery packs. A water-cooling system for Hyundai and Kia's EV battery packs, rather than conventional air cooling, have yielded further increases in range without increasing physical dimensions. This development means battery cells in Hyundai and Kia EVs can be packaged much more tightly, with water-cooling channels taking up less space than air-cooling channels, increasing battery density by up to 35 percent. reduced battery consumption This innovation means the latest EVs from Hyundai and Kia offer around twice as much driving range and battery capacity compared to the their first-generation EVs – and are capable of traveling significantly further on a single charge. For example, the first-generation Soul EV offered owners an electric driving range of around 180km from a single charge of its 30kWh lithium-ion polymer battery pack. Hyundai and Kia continue to hone and improve the heat pump system and other innovations The second-generation Soul EV, with a 64kWh battery occupying a similar amount of space, is capable of traveling up to 386km on a single charge. A study carried out by Korea's Ministry of the Environment on the Hyundai Kona Electric and Kia Niro EV found that the heat pump significantly reduced battery consumption in cold conditions. heat pump technology When each car was driven in temperatures of -7°C (19°F) with the HVAC system activated, they were able to maintain 90 percent of their driving range compared to journeys undertaken at an ambient 26°C (79°F) – setting a new benchmark for other EVs. By contrast, many EVs offered by other manufacturers saw their total electric driving range drop by between 18 and 43 percent under the same test conditions. Hyundai and Kia continue to hone and improve the heat pump system and other heat management innovations, with the technologies currently informing the development of next-generation EVs from each brand. Under its 'Strategy 2025' plan, Hyundai Motor aims to sell 670,000 battery EVs and FCEVs (fuel cell electric vehicles) annually and become a top-three EV manufacturer by 2025. Kia's mid- to long-term strategy, dubbed 'Plan S', will see the brand's line-up grow to 11 EVs over the same timeframe.

IT Tech Packaging, Inc., a globally renowned manufacturer and distributor of diversified paper products in North China, has announced that its operating entity in China, Hebei Baoding Dongfang Paper Milling Company Limited (Dongfang Paper), expects to launch the construction of a combined heat and power generation project utilizing biomass technology (Biomass CHP project) with the total construction area of 80,373 square meters which is located in its Wei County production base. Biomass CHP The company's biomass CHP project included in the 13th Five-Year Biomass Power Generation Program of Hebei Province has recently been approved by the Development and Reform Commission of Xingtai Municipality. Biomass CHP, a kind of renewable energy power and heat generation, utilizes biomass resources, mainly crop straw and forestry waste. 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."
Emerson introduced two new compressed air dryers designed to significantly extend maintenance intervals, minimize downtime and reduce energy costs in rail applications, including brakes and door control. Typically, air dryers have an average service interval of less than two years. The AVENTICSTM RDD (Roll-Up Dessicant Drying) and RDDmin air dryers, have a service interval of eight years or 25,000 operating hours. The new products feature a proprietary adsorption medium that removes humidity from compressed air systems more efficiently, reducing energy usage with a smaller envelope size and weight. The dryers’ shock and vibration resistant design further enhances their reliability in tough rail applications. brake control circuit Humidity in compressed air can cause corrosion and ice blockages at low temperatures, often disabling door systems or freezing valves in the brake control circuit. Until now, conventional dryer systems relied on a granular adsorption medium. The shocks and vibrations that occur during rail operations cause channeling, air bypass and dust generation, which leads to a significant loss in drying performance. Emerson’s AVENTICS RDD technology uses adsorbent crystals immobilized in a durable polymer support structure Consequently, the dew point increases. High water loading can cause a breakdown of the granulate bed resulting in frequent material changes and a reduced service life. To solve these problems, Emerson’s AVENTICS RDD technology uses adsorbent crystals immobilized in a durable polymer support structure, which is produced in a continuously embossed sheet and rolled up to tightly fit into a barrel-type housing for high shock and vibration resistance. excessive water loading Unlike competing products using desiccant beats, the AVENTICS dryers resist excessive water loading and fully recover afterwards. This ensures constant performance throughout the lifetime of the product and reduced life-cycle costs. The RDD dryer is used for main air supplies on trains, whereas the RDDmini is used for auxiliary air supply, to driver seats for example. The efficient design means that the overall envelope size for both dryers is half that of other dryers currently available on the market, allowing for smaller envelope sizes and lower unit weight. The moisture uptake allows for a much higher efficiency air consumption rate of less than 15%, which reduces energy costs. Purge loss typically ranges above 20% for conventional products.
Many of us are spending more time at home. Given that work and home lives are becoming more intertwined, it makes sense to create a “comfort zone” in the place where people spend the most time. I am speaking about the benefits of zoned HVAC comfort control through duct-free split systems. Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house. Maybe they want to cool their home gym to 68 degrees while leaving the playroom at 76 degrees. Duct-free systems offer the ability to individually set preferred comfort settings for each individual zone or room in the home. Control the temperature, humidity and even the volume and direction of airflow, all according to personal preference. Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house Pandemic trends During the pandemic, one trend we are seeing is more consumers adding duct-free systems to spare rooms to function as a home office or the conversion of a garage for a home theater or as a social-distanced gathering place for family and friends. There are many options today to meet all of these needs and more. LG offers a variety of stylish, duct-free indoor units ranging from a smoked glass mirror finish to traditional white. You can offer your customers the ability to customize their space with the Art Cool Gallery, a unit that looks like a picture hanging on the wall, allowing them to add their own artwork or photographs. With so many options, there is no reason not to have the comfort you deserve. Each unit is powered by an energy efficient inverter with heat pump technology – some offering up to 28 SEER. The SEER calculates air conditioning and heat pump cooling efficiency. The higher the number, the less you will spend on energy costs. These systems – many of which are ENERGY STAR® certified – are built with cost-savings in mind, so whether it is low installation costs or reduced lifetime costs, your customers will be surprised to see the money they will save with duct-free HVAC technology. app technology “Smart” indoor units from LG come equipped with Wi-Fi capabilities and on some other models, this function can easily be added using a separate module. This allows control via the included wireless controller or from a smartphone. The free app for both iOS and Android is called LG ThinQ®. This is where we have a unique advantage over the competition. The app is the same communication platform used with LG home appliances and TVs. When a homeowner presses the “away mode” it will set all of the indoor HVAC units to their predetermined temperature, and at the same time other smart appliances in the home - refrigerator, dishwasher, washer and dryer - will be set to a low energy consumption mode. Imagine the savings! The app also allows the control of HVAC modes (Heating, Cooling, Dehumidification, Auto Changeover, or Fan Only), temperature, airflow direction/vane movement (up, down, side to side), fan speed and of course power (on/off). Users can control one or several units and each can be set up for group control. For instance, a parent might want to control all of the zones in the house, but only give children control of their room. Duct-free units give everyone their own personal level of comfort. There is also the option of installing these units in rooms that are typically warmer in the summer months or difficult to keep cool as temperatures rise. A connected home LG units can also be voice-controlled when paired with Amazon Alexa or Google Home For a more connected home, any of the LG units can also be voice-controlled when paired with Amazon Alexa or Google Home. This offers the convenience and freedom to use simple commands to set a desired temperature in various areas, such as: “Alexa, set the master bedroom to 70 degrees,” or “Alexa, set the office to heating.” So how does it work? The inverter compressor can adjust the speed of the compressor in 1 hertz level increments to match the load. This allows the outdoor condenser to operate at the minimum-required hertz level to meet the load and achieves a desirable energy efficiency at lower sound levels. The indoor unit also maintains greater cooling and wicks the moisture from the air to provide lower humidity levels. The reward is monthly energy savings on utility bills. These duct-free systems allow homeowners to efficiently make the most of all available spaces.
Around the world, advanced building automation systems (BAS) in smart buildings are driving demand for smarter HVAC systems. Modern HVAC systems can improve energy efficiency and mitigate potential health problems associated with indoor air quality and ventilation. In fact, HVAC improvements and building controls are expected to be a big U.S. investment in 2021. But capitalizing on this opportunity will take more than smarter HVAC systems. It’ll require a smarter approach to communications and BAS integration. Increase of data traffic in the network Over the last few years, the industry has seen a dramatic increase in the bandwidth demanded by building automation systems. More nodes, bigger packets, more security, all of these things increase the amount of data traffic in the network. Legacy communications technologies like RS-485 struggle to handle all of this data. To compensate, system designers have shortened bus lengths, developed costly gateways, and added complex protocol conversion for BAS integration. Because, in most implementations it’s just not practical or cost effective to install new high-speed cabling. A high-speed wireline communication standard called HD-PLC that is developed specifically for today’s industrial IoT Now, there’s a better option: a high-speed wireline communication standard called HD-PLC that is developed specifically for today’s industrial IoT and smart building applications. In 2017, after careful evaluation of various technologies, LonMark International adopted HD-PLC as its new channel standard. And last October, the Consumer Technology Association (CTA) ® approved ANSI/CTA 709.8 LON HD-PLC (High Definition Power Line Communication) as a new standard by the American National Standards Institute (ANSI). LON HD-PLC technology for smart HVAC systems In this article, one will learn how LON HD-PLC technology is enabling a new generation of smart HVAC systems, using the existing building wiring. The Problem: Serial Networks Are Stretched to Their LimitsTraditional building automation systems rely on direct-digital control communication protocols over RS-485 signal levels. However, with a throughput of just 9.6kbps, RS-485 struggles to meet the demands of advanced HVAC applications. Overview of Wired Technologies for Building Automation Systems (BAS) In RS-485-based systems, each platform domain requires a gateway to translate proprietary protocols into IP. As such, the building administrator has limited control over individual devices in the network. To extend the network path from BAS to the digital or analog I/O module, the network wiring needs to be installed to connect a controller device over Fieldbus I/O systems. Central air conditioning system based on RS-485 While protocols like BACnet/IP, LON IP, and KNX IP enable system integrators to increase bandwidth and extend IP beyond the gateway; they require the installation of new wiring, which is time-consuming and expensive. System integrators also have to reduce bus lengths and add control equipment to support the high bandwidths required by modern applications. To enable BAS modernization and replace costly gateways, there’s a better solution – HD-PLC Bridging to connect Ethernet networks to other wireline (twisted pair, powerline, phone lines, coax, etc.) and wireless networks (WiFi, BLE, etc.). Megabit data rates for long cable lines LonMark International adopted HD-PLC as the new channel standard for high-speed wireline networks. Based on the IEEE 1901 and ITU-T G.9905 international standards, HD-PLC combines IP-based broadband communication with an innovative multi-hop technology to reliably achieve megabit data rates over several kilometers of cabling (AC/DC power lines, twisted-pair, coax, etc.). The architecture supports up to 1024 nodes and is packed with innovations such as free topology, mesh networking with dynamic traffic routing, and crypto-strong AES-128 encryption. LON HD-PLC platform implements an Ethernet-like transmission, wherein devices act as an Ethernet gateway This new standard enables native LON communication over any IP transport such as Ethernet and Wi-Fi, as well as interoperability with IP-based web services so that building and industrial automation systems can seamlessly and securely interoperate with cloud and IoT applications. LON HD-PLC platform implements an Ethernet-like transmission, wherein devices act as an Ethernet gateway in parallel, enabling double use for all IP-based solutions. It creates a single control system to aggregate data and detects hidden faults in HVAC operations. Plus, IP networks can be used as a native network medium for LonWorks, so the use of LonWorks/IP-only devices is also possible. Central air conditioning system based on HD-PLC instant speed upgrade - from just kilobits to megabits- Built to seamlessly couple Ethernet and RS-485 devices, the LON HD-PLC Bridge enables system designers and integrators to upgrade to higher speeds, longer ranges, more nodes, and more advanced feature-sets over their existing wiring infrastructure with minimum cost. That way, everything connected to it becomes a part of the Internet of Things – acting as data points, to improve the operating efficiency of smart HVAC controls. Using IP-based communications (IPv4 or IPv6 multicasting), HD-PLC provides LON systems with an instant speed upgrade- from just kilobits to megabits-without needing to add or replace wiring. Especially designed for building automation, IPv6 provides a cost-effective transport mechanism for complex control systems to communicate with devices. In addition, IP based communication enables the use of existing IP based tools, like Wireshark, reducing the learning curve for system designers and engineers – which means less maintenance and ultimately lower cost. With this transformative wireline communication technology, manufacturers can effectively build a robust infrastructure into buildings today, ensuring the future-readiness for intelligent HVAC of tomorrow.
Behind most modern portable and fixed evaporative cooling systems is a component known as rigid evaporative media. At first glance, this component appears to be a simple block of corrugated cardboard-like material. Outside appearances are often deceptive though, and this is most assuredly the case with evaporative media. Within the intricately and proprietarily designed flutes and angles is the ability to cool many everyday aspects of our lives, from data centers that support our daily online lives to the agriculture environments where our food is sourced. While you may have never heard of evaporative cooling, it is all around you. The simplest definition of evaporative cooling is cooling with water. Used since the ancient Egyptian days to generate natural cooling, a few examples of evaporative cooling at work include the cooling sensation felt when climbing out of a swimming pool, or feeling the cool breeze blowing across a lake. By evaporating water, the temperature of the air in contact with the liquid water will lower as an endothermic reaction takes place. During this reaction, the liquid water changes to a gas state and the temperature of the air lowers. This is where rigid evaporative media comes into play. The simplest definition of evaporative cooling is cooling with water Rigid Evaporative Media As mentioned earlier, rigid evaporative media is the technology behind portable evaporative coolers and fixed evaporative cooling applications. The quality of the evaporative media chosen for these systems makes a crucial difference in the effectiveness of the cooling achieved. The expert engineering of rigid evaporative media ensures even water distribution and is imperative to maximize the interaction between air and water for the most efficient evaporation, and therefore, the most effective cooling. Composing the media of only superior raw materials is the key aspect to producing strong media that does not easily break down in water, and it is designed in a way that the water self-cleans the media when it runs across it. Higher-end evaporative media is coated with a proprietary blend of resin material to ensure longevity and inhibit the growth of algae. Reputable evaporative media manufacturers have the ability to meet specific performance specifications, considering a customers’ desired pressure drop, saturation, wet out rate and more. Evaporative cooling offers an energy efficient, environmentally friendly and economical cooling solution over traditional air conditioning methods. There is no need for refrigerants or a compressor, meaning there is no additional heat to vent from the system. The expert engineering of rigid evaporative media ensures even water distribution and is imperative to maximize the interaction between air and water for the most efficient evaporation So where exactly does this cooling technology meet daily life? Food chain supply Did you know that agricultural applications from poultry houses, dairy farms, swine industries and greenhouses all utilize fixed evaporative cooling? Before we find food options on grocery store shelves or restaurant tables, there has been a process to provide the freshest, best-quality option for consumers. Meat and dairy production Whether talking about egg-laying hens, broilers or free-range chicken, it has been proven that cooling improves the production and efficiency rates in chicken houses. The same is true for the dairy industry. Cooling the cows and reducing heat stress improves overall milk production. When it comes to meat production, it should be noted that animals such as pigs and broilers do not have sweat glands. Due to this physiological limitation, heat is intensified if their environment is not well managed. It’s important to keep these animals cool – from small, artisan farms to large, agricultural operations – to ensure production meets the quality and quantity demand of the food chain. Greenhouses Greenhouses are another area that must maintain a delicate balance of keeping temperatures from soaring when dealing with certain fruits, vegetables, herbs and flowers. As growers seek to find year-round crop growing options, evaporative cooling in greenhouses plays an important role in providing nutritious options in the food supply chain. This touches consumers who have become more conscientious about buying local and embracing farm-to-table practices. Data centers They are the backbone to the fibers of our online and social media lives. Computers that power our cloud data run 24/7. Cooling the air surrounding these machines via the fixed evaporative cooling system helps reduce the load on a traditional air conditioning approach. According to a trade publication on the matter, growing demand for digital services and data centers means effectively meeting the power requirements of the IT industry in some geographies, which often means more and larger facilities. Media streaming makes up the biggest portion of global traffic, and it is steadily increasing to become the energy guzzler of the internet. This consumption essentially equates to energy usage and high demand on data centers during high traffic times such as the first half of 2020 during the unprecedented global quarantines that were put in place. Increased online data usage through work from home initiatives and added streaming applications will only increase the burden on data centers. Reducing the heat generated is a benefit of using a fixed evaporative cooling system to ensure data centers run efficiently, and consumers have the internet and social platform usage they want when they want to access it. Gas turbines Gas turbines are used to create mechanical energy from a combustible fuel source to provide electrical energy to homes and businesses. Studies have shown gas turbines located in regions that experience high seasonal temperatures are prone to significant losses on both efficiency and output during these high-temp seasons. In response, engineers have begun installing evaporative coolers to cool the ambient air, resulting in increased performance and output. Portable evaporative coolers They provide cooling in a variety of settings from automotive shops, manufacturing facilities, and warehouses to outdoor sporting events and recreational settings, as well as home patios. Formerly referred to as swamp coolers, modern-day evaporative coolers are more energy efficient and effective thanks to the quality of rigid evaporative media that evaporates the water. Portable coolers create mobile cooling where traditional air conditioning is ineffective or cost prohibitive. As countries and governments focus more and more on the ravages of heat stress and heat-related illness in the work place, employers are looking to evaporative cooling as an effective and cost-efficient method of protecting workers and avoiding government fines. As consumers look for more green options, evaporative cooling is considered to be an environmentally friendly solution. Utilizing natural elements and staying away from harsh chemicals used in traditional air conditioning options, rigid evaporative media in a fixed or portable system can provide efficient and cost-effective cooling relief.
Members of a family were eating lunch in a restaurant in Guangzhou, China, seated at a table below an air outlet and return air inlet for the central air conditioner. At another table sat a family who had just traveled from Wuhan, Hubei Province, China. There was another family seated at a third table. One of the diners experienced the onset of fever and cough later in the day and went to the hospital, later diagnosed with COVID-19. That was on Jan. 24, 2020. By February 5 – some 12 days later – a total of nine others from the three families had become ill with COVID-19. The only known source of exposure for the affected persons was at the restaurant, and researchers have singled out droplet transmission prompted by air-conditioned ventilation as a likely means of the virus transmission. COVID-19 droplet transmission The Centers for Disease Control and Prevention (CDC) is reporting on the case under the title “COVID-19 Outbreak Associated with Air Conditioning in Restaurant, Guangzhou, China, 2020.” Examination of the potential routes for transmission of the disease in this instance concluded that the most likely cause of the outbreak was droplet transmission. Furthermore, researchers theorize that strong airflow from the air conditioner could have propagated droplets among the three tables. Lower concentrations of aerosols might have been insufficient at greater distances to cause infection This route of transmission is probable because the people at the other two affected tables were further than 1m away, say researchers, beyond the usual range for large droplet transmission. Generally, larger respiratory droplets remain in the air for only a short time and travel only short distances, 1m or less. Also, in this case, pre-symptomatic transmission is likely, since the initial patient was asymptomatic during the lunch. Aerosol Transmission Appears Less Likely Virus-laden smaller aerosolized droplets can remain in the air and travel longer distances; however, none of the staff or other diners in the restaurant were infected, which makes this route of transmission less likely. Because aerosols tend to follow the airflow, lower concentrations of aerosols might have been insufficient at greater distances to cause infection in other parts of the restaurant. Avoiding recirculating indoor air “We conclude that in this outbreak, droplet transmission was prompted by air-conditioned ventilation,” say the researchers. “The key factor for infection was the direction of the airflow. To prevent spread of COVID-19 in restaurants, we recommend strengthening temperature-monitoring surveillance, increasing the distance between tables, and improving ventilation.” Researchers also point to the value of daylight to impact the viability of germs The research was conducted by the Department of Control and Prevention for Infectious Disease at the Guangzhou Center for Disease Control and Prevention. The case supports recommendations by experts at the University of Oregon and the University of California, Davis, to take care not to recirculate indoor air which could increase potential contamination. Impact of natural light on novel coronavirus Rather, bringing more air from outside and using higher rates of air exchanged can help to dilute indoor contaminants, including viral particles. A solution might be as simple as opening a window. Researchers also point to the value of daylight to impact the viability of germs in an indoor environment. However, they say more research is needed to fully understand the impact indoors of natural light on the novel coronavirus.
Since the beginning of the COVID-19 pandemic, HVAC systems have been at the center of concerns such as indoor air quality and the need to minimize potential exposure. At the local level, HVAC installers have increased their efforts to keep equipment and supplies clean, and technicians are wearing gloves and masks as protection to keep customers safe. Many HVAC companies have also sought to give back to local communities hard-hit by the pandemic. As an industry, HVAC has remained committed to maximizing service to communities, and to each individual customer. Pandemic response For example, Johnson Controls has been part of the pandemic response from the beginning. The company first responded to the developing crisis in Wuhan, China, where local personnel worked to fulfill urgent needs for new hospitals. Local personnel worked to fulfill urgent needs for new hospitals As the pandemic evolved, Johnson Controls also implemented local and regional contingency plans across the globe to ensure employee safety and customer support. “As a global company, we have been addressing this crisis from the very start and are proud of our frontline leadership responding in every corner of the world,” says George Oliver, Johnson Controls Chairman and CEO. He pledged the company will do whatever is needed to keep essential products, services and personnel up and running. Helping Hospitals Johnson Controls’ products and services in the HVAC category are essential to hospitals and operating rooms and are a necessary component for operation of almost all the Critical Infrastructure Sectors recognized by the U.S. Department of Homeland Security. Properly ventilated buildings are critical to improve air quality and prevent the spread of disease and secondary infection. According to Johnson Controls, it is essential to maintain systems and keep them in service where people continue to live and work. Industrial refrigeration is also vital in markets ranging from food and beverage processing to the petrochemical industry. Here is another example of the HVAC community’s involvement in responding to the COVID-19 crisis: AAON, a semi-custom commercial HVAC equipment manufacturer, provided 50-ton customized HVAC units for the Stony Brook Temporary Hospital on Long Island, just east of New York City. The Tulsa, Okla., company provides 44 of the units, totaling 2,200 tons of HVAC apparatus, which equates to the cooling capacity of more than 700 single-family homes. Aiding the pandemic AAON worked around the clock to make the equipment and ensure the units arrived in New York City on a tight timeline. AAON’S New York sales office had called President Gary Fields to inquire about the company’s ability to meet the hospital’s need. A 1,038-bed temporary hospital to treat non-COVID-19 patients during the pandemic was constructed A 1,038-bed temporary hospital to treat non-COVID-19 patients during the pandemic was constructed at Stony Brook University. The Army Corps erected four temporary tent-like structures near the university’s athletic fields as part of the New York State initiative to relieve local hospitals during a spike in patients due to the pandemic. Ultimately, like many temporary facilities built in response to the pandemic, the hospital was not used. However, the facility will be ready in case it is needed for a second wave of the pandemic.
The U.S. Environmental Protection Agency has rolled back a standard set under the Obama administration to require leak repair and maintenance for industrial and commercial refrigeration and air conditioning equipment containing 50 or more pounds of hydrofluorocarbons (HFCs). The industry embraced HFCs, which are potent greenhouse gases, as a replacement for ozone-depleting refrigerants such as chlorofluorocarbons (CFCs). The requirements that have now been rolled back merely extended the leak prevention requirements already in place for CFCs to the newer replacement chemicals. Since the rollback, leak repair and maintenance requirements now only apply to Class I and Class II ozone-depleting substances. Environmental Groups Environmental groups are among those opposing the standard rollback, including the Natural Resources Defense Council (NRDC). “This rollback will fuel the climate crisis by adding more super-polluting HFCs to the atmosphere each year, in an amount equal to the carbon pollution from a million cars,” says David Doniger, Senior Strategic Director in the Climate & Clean Energy Program at the NRDC. “It will save industry just $24 million a year, a pittance when spread across thousands of industrial facilities.” His rollback will fuel the climate crisis by adding more super-polluting HFCs" The bipartisan American Innovation and Manufacturing Act, which has been introduced in the Senate and the House, may provide an opportunity to reinstate the requirements. The U.S. Chamber of Commerce and the National Association of Manufacturers support the new legislation. The final rule change to Section 608 of the Refrigerant Management Regulations was first proposed in 2018. The Air Conditioning Contractors of America (ACCA) had sought to retain the leak repair provisions in the best interest of the environment, equipment maintenance and the consumer. Properly charged equipment operates more efficiently than improperly charged equipment. Lesser charged equipment can also accelerate failure rates, lower system performance and decrease energy efficiency. Inspecting equipment Under the new rule, equipment owners no longer have to inspect periodically for leaks or report leaking appliances to the EPA. They do not have to repair appliances to a certain level or verify with testing. They also do not have to retrofit or retire appliances that are not repaired, or maintain records related to any of the above. Leak detection and repair is widely considered an industry best practice, and the industry has invested in management, leak detection and repair programs to support compliance. Therefore, revising the standard may have little impact on HFC emissions, according to some industry sources. In any case, existing refrigerant management best practices should remain in place, say the experts. The rule change is also likely to cause confusion since some refrigerants are still subject to leak detection requirements and others are not. The rule change is also likely to cause confusion Existing standards Even with the relaxation of the leak repair requirements, existing standards for purchase, handling, recovery and reclamation of HFCs remain in place and are also considered best practices. EPA’s proposed rule from 2018 had considered rolling back those rules, too. Among those supporting the recent EPA rollback of leak repair and maintenance requirements was NEDA/CAP, a multi-sector manufacturing coalition of companies that include the Boeing Company, BP America, Eli Lilly & Company, ExxonMobil Corp., Georgia-Pacific, Intel Corp., Koch Industries, Merck & Co, NewPage Corp., Occidental Petroleum Corp., Procter & Gamble and Weyerhaeuser.
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.
In practice, incumbent building services can help architects and designers overcome planning and structural constraints. Building typology comes in all shapes and sizes, each with its own unique design criteria. Frequently building services, heating, ventilation and air conditioning in particular can be challenging to integrate into a building design but experience shows that this does not necessarily have to be the case. Working with underfloor air conditioning over the past 30 years,) AET Flexible Space can demonstrate that such systems have a number of benefits in design application that ultimately make it the ‘system of first choice’ when compared with alternative overhead and perimeter air conditioning systems and their practical application. ease of reconfiguration Principally there are two different types of underfloor air conditioning (UfAC) system, the first being a full underfloor solution, with zone units supplying conditioned air, and receiving spent air via the plenum beneath the raised access floor. As it effectively becomes the ventilation zone, the plenum is divided into supply and return air paths using fire-resistant, air-tight silicone cloth. As there is no need to divide the floor plenum, this option permits freedom to maximize the floor plate This first system is undoubtedly the best option if the brief is to expose ceilings and maximize headroom in refurbishments as it allows total elimination of any ceiling void. Another option is a system with a zone unit which supplies conditioned air via the floor plenum, but receives spent air at high level or via ceiling extract grilles. As there is no need to divide the floor plenum, this option permits freedom to maximize the floor plate as well as future flexibility due to the ease of reconfiguration. ceiling based air conditioning Refurbishment projects in the UK often have specific design criteria, dictated either by the client, or frequently by planning conditions. 8 Waterloo Place in the St James’ area of London is a classic example. The fabulous building constructed in the early 1900’s is Grade II listed and features ornate vaulted ceilings and decorative plasterwork cornices. Both the client and the architect specifically requested no services at high level in order to preserve and highlight these features using bi-directional up and down lighting. This immediately eliminated ceiling based air conditioning as an option. The seven story building also has differing floor to ceiling heights on each floor, proving to be an additional challenge for investor Barings, whose aim was to create the highest quality, modern office space at the prestigious Mayfair property. high profile tenancy A full underfloor air conditioning system was subsequently specified for floors 1-4 of the building, which all had an existing 300mm floor plenum. The height restriction of the dormer fifth floor only permitted a very shallow floor plenum, so a perimeter system was adopted for this space. The end result of the refurbishment was 70% occupancy in a very short period of time, the building attracting high profile tenancy and achieving high levels of rent, “a truly special building”, comments the MD at Barings Real Estate. Another key building characteristic is the small windows and low natural light levels Another refurbishment project to reference is 33 Glasshouse Street, London, prominently located on the corner with Regent Street, a fusion of three buildings and with a Grade II listed façade, varying slab heights and low floor to ceiling heights, developer Hermes set about a full “Cut and Carve” structural reconfiguration to form larger, deeper, open plan floor plates and increase the floor to ceiling height to 3.3m on floors 3-7. raised floor system Another key building characteristic is the small windows and low natural light levels. Underfloor air conditioning was specified to help maximize the floor to ceiling heights and permit the greatest level of natural light through the deep floor plates. Perimeter heating and cooling would not have been effective given the deep floor plates and ceiling based air conditioning would have required a ceiling void that would virtually cover the low level windows, severely restricting light penetration. Even with the introduction of a raised floor system and underfloor services, the down stand beams are clearly visible underneath the window line, but this only serves to highlight the unusual building characteristics in an effective way. The end result, another achievement by the project team with a successful outcome. Prime, modern office space attracting the highest caliber occupants, commanding premium rates. overhead services At Cathedral Hill in Guildford, UfAC was used to cool the atrium area where overhead services could not be used September 2018 saw the completion of the tenant fit-out on three floors of the building for one of the world’s biggest tech giants. Design freedom with underfloor air conditioning is not only apparent in refurbishment projects, over the last three decades, the company's systems have also helped new builds achieve their design objectives, whether by using a full underfloor system, or simply integrating floor recessed Fantiles with Displacement Ventilation or other HVAC systems. At Cathedral Hill in Guildford, UfAC was used to cool the atrium area where overhead services could not be used. At First Point, Gatwick, adopting UfAC saved 2m in height compared with an identical building at Heathrow with ceiling services. cellular meeting pods At the expansive Sky Central Campus, UfAC Fantiles are used to enhance the Displacement Ventilation system by boosting cooling in the cellular meeting pods, and at the award winning Here East Innovation Centre, UfAC has been innovatively integrated with overhead services offering fully flexible and functional workspace for the start-up community. The above are just a few examples of how innovative thinking and design application has encouraged the uptake of underfloor air conditioning and promoting it as a viable solution to wide ranging design challenges in new build and refurbishment projects, helping property owners and agents to differentiate their offering and create world class workspace.
AET Flexible Space recently completed the supply and commissioning of underfloor air conditioning equipment for the new ninth floor at 55 Gresham Street. Situated near the Guildhall in the heart of the City, the 84,038 sq. ft., eight story building was acquired in 2014 by Angelo Gordon and Beltane, extended and fully redeveloped to provide 11 floors of Grade-A office space over 121,569 sq. ft. underfloor air conditioning The redevelopment included the creation of a new level access corner entrance and reception at Wood Street and Gresham Street, with remodeled cores, extensions of the floorplates at ground to sixth floors and replacement seventh and new eighth and ninth floors created through the removal of the existing ninth floor plant. New services are supplied throughout and new composite stone facades to the south, west and north are well in keeping with the urban locality. The design is characterized by its imaginative use of materials and historical references The design is characterized by its imaginative use of materials and historical references. Designed by Fletcher Priest Architects, with mechanical, and other design services provided by consultant, Waterman Group, underfloor air conditioning was specified for the new ninth floor terrace in order to maintain the architectural vision. Direct Expansion coils By placing services within the floor void, the remaining available space and floor to ceiling heights were maximized by eliminating the need for ceiling based pipe and ductwork. The two zone system on the ninth floor terrace is served by two CAM-C25 downflow units with Direct Expansion coils and a total of thirty standard TU4 Fantiles with EC fans for enhanced energy performance. This considered redevelopment is a building designed with the occupier in mind and testament to this approach, the entire building was pre-let prior to practical completion to global giant, Investec Asset Management. Main contractor ISG handed over the £34 million project at the end of 2018 and has a BREEAM target of Excellent.
One Benjamin Street, situated directly opposite Farringdon Station on the corner of Turnmill Street, is a fabulous new build with mixed use accommodation comprising retail and commercial space as well as residential penthouse apartments. The prominent site, owned by The Girdler’s Company for some 400 years, formerly featured three individual buildings of different style and character, which were considered unfit for purpose and replaced by one high quality single building. Designed by world renowned architect AHMM, and inspired by the character of local Victorian warehouses, and craftsmanship at the core of The Girdler’s Company, the new build offers 1692 m2 of high quality, sustainable office space with highly flexible, column free floor plates and BCO recommended floor to ceiling height of 1.8m on the 1st to 3rd floors. air conditioning system Underfloor air conditioning was recommended by Main Contractor who had experience of floor level air conditioning The overall design brief was to provide optimum flexibility when adding or re-arranging fittings for incoming tenant requirements, and the AET Flexible Space underfloor air conditioning system specified fits this brief perfectly. Underfloor air conditioning was recommended by Main Contractor, Knight Harwood who had experience of floor level air conditioning from another London refurbishment in Soho Square. M&E Consultant, Scotch & Partners were satisfied that the system could cater to demand, whilst offering greater flexibility for future change of use than the originally proposed perimeter heating and cooling systems. The system specified is a CAM-V system with underfloor supply air and return air received back to the zone unit at high level. The CAM-V system is the best solution for future flexibility as there is no underfloor air baffle to reconfigure should a layout change be considered. supply conditioned air Each of the office floors is split into two zones, with a CAM-V33 downflow unit serving each zone. A total of 105 recessed Fantiles, which supply conditioned air into the space, are evenly distributed across the six zones. The completed new build with its reinforced concrete frame, flat slab construction and exposed concrete soffits, columns and walls offers contemporary interior styling, and the exterior detailing combining feature brickwork, exposed polished concrete medallions and signature façade cladding incorporating the client’s crest is a quality improvement to the local streetscape and a testament to the client and project team.
