Honeywell announces a new airborne particle analyzer that uses artificial intelligence and cloud computing to enable HVAC service providers and environmental testing professionals to better inform home and building owners of the quantity and type of particles present in the air. Airborne particles, allergens and spores affect the quality of life for more than 400 million people worldwide – for example, poor indoor air quality has been found to cause allergic rhinitis, which Americans spend more than $3 billion each year. Honeywell Air Detective is a breakthrough technology that can capture images and details of those allergens and particles in the air. Indoor air quality The Honeywell Air Detective allows HVAC service providers and environmental testing professionals to evaluate indoor air quality in near real-time with an easy-to-use mobile app that can be accessed on a tablet or emailed directly to the homeowner. This detailed evaluation, including images of the particles, can help homeowners and building managers make informed decisions about how to improve the air inside their homes or buildings. "Understanding what is in the air inside your home or building is a top priority for owners. HVAC, environmental testing, and other service professionals are looking for innovative solutions that will help them test air quality on the spot and determine the specific equipment, service and system upgrades needed to improve the indoor air quality," said Sarah Martin, president of Honeywell's Sensing and Internet of Things (IoT) business. Industrial analytics software This portable analyzer has already been deployed by environmental testing companies and HVAC distributors "We have developed a cost-effective, portable analyzer that uses holographic microscopy and cloud technology to 'take pictures' and classify airborne particles. Honeywell continues to provide solutions to help improve air quality for people while at home, on the job or when traveling." The Honeywell Air Detective is a handheld and lightweight, lens-less microscope that can be easily carried by a field technician to classify types of particles present in the air, including spores and various pollen species. It leverages powerful industrial analytics software and deep learning algorithms that are trained on specific pollen and spore species. This portable analyzer has already been deployed by environmental testing companies and HVAC distributors, such as Yandle-Witherspoon Supply, Inc. HVAC air cleaning systems "HVAC providers are being asked more and more to explain the specific airborne particles, spores and allergens in the air and suggest filters or solutions to improve air quality and comfort," said Philip Guy Jr., Territory Sales Manager, Yandle-Witherspoon. "Honeywell's particle analyzer has proved to be useful in field trials by helping our technicians pinpoint the specific pollen and spores present in the air so that we can work together with homeowners to make informed decisions and take action to improve their HVAC air cleaning systems and provide additional services." The Honeywell Air Detective uses disposable air analysis cartridges to collect particles, photograph them, and automate the classification process onsite. In the past, professionals would have collected and shipped the air sample off to a lab where a technician would be spending tedious hours analyzing the sample under a microscope before providing a detailed report. The device and consumable cartridges are available for sale at select HVAC distributors.

The past six months have been busy for those in HVAC as offices are updated and made safe for people to return. In addition to the various standard checks that need to be carried out, more care is being taken in relation to air movement and filtration to prevent the spread of disease. There is evidence that at least some of the COVID-19 virus can remain suspended in the air and infectious for up to 3 hours. While this is not the main form of transmission, it is vitally important, especially as we are seeing a second increase in infections, that all measures are taken to prevent the spread of the disease. Sick building syndrome In addition to the fundamental elements of HVAC in public buildings, the sector should be looking to the future of technological use; whether COVID-19 is completely wiped out or lingers in the population, we may be at risk of more new diseases in the future. Although maintenance is one of the least visible of building services, it has long played an important role in ensuring the health of buildings. Decades ago, the concept of sick building syndrome was first introduced, showing quite how important our environment is to health. Now, we are being reminded of this on a daily basis in ways that have never been under such scrutiny. We are suddenly hyperaware of what we have touched and who else is breathing our air. In many ways, this new awareness of the unseen is a boon for the sector that has so long been behind-the-scenes, but it also puts it to the test. Potentially stagnant pockets There are numerous recommendations from experts on how to increase safety Governmental guidelines have not specifically required that ventilation and air conditioning be increased in the workplace. Yet, there are numerous recommendations from experts on how to increase safety. At the low-tech end of the spectrum, the use of ceiling and table fans to increase movement in potentially stagnant pockets of air has been suggested. At the other end, technologies that have long been growing in popularity, such as remote monitoring, will really come into their own in the coming months. A particular challenge for the industry as workers return to the office under social distancing guidelines will be accessing certain areas for maintenance. For as long as the virus remains in the population, risk assessments for work will be more complex and non-essential jobs will likely be put on hold where possible. Optical remote sensors Intelligent technology and monitoring systems are already driving the market and will play a role in minimizing contact with others when visiting a site. There is already a great range of tools available: wired sensors, wireless sensors, and optical remote sensors. These allow organizations to monitor vibration, temperature, acoustics, and the power of numerous assets remotely and in real-time. Any issues can be addressed as soon as they arise, minimizing the cost and time that an engineer may need to be in the building. Installing these technologies while buildings are still unoccupied or only partially occupied will also reduce the risk of exposure of engineers to the virus and will improve the efficiency and prolong the life of important assets. Whether a second lockdown takes place or not, these tools will protect building services. Motion-Activated air conditioning Other sensor-based features such as motion-activated air conditioning also have great potential Other sensor-based features such as motion-activated air conditioning also have great potential. These can manage the new hygiene anxiety which pervades public places at the moment. In the longer term, they can be a means of building sustainability practices into the workplace, using power only when needed. Internet of Things (IoT) features such as occupancy sensors have long been growing in popularity to create buildings which are more energy-efficient and promote productivity. Many of these features are demonstrating added value during the pandemic. Occupancy sensors, for example, can be used to ensure that buildings do not exceed safe numbers for social distancing. HVAC systems will be integrated ever further into the IoT approach. Some features of virus reduction, however, have posed a challenge for systems. Air conditioning systems Air conditioning systems, for example, can best reduce the risk of viral transmission through increasing the amount of air which is brought in from the outside into the systems. This will reduce the amount of recycled air but will also increase the temperature fluctuations within the buildings. Other recommendations have included reviewing ventilation strategies, increasing ventilation operating times, deep cleaning filters, and replacing filters more often. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client All of these can potentially see an increase in time and cost required by the client at a time where many companies have been stretched financially. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client in the long run if their employees lose time to illness but it still may be a temptation. Strong working partnership FM providers must work closely with clients to understand their individual fears and needs in such turbulent times. For Anabas, we believe demonstrating expertise and experience is a means of reassuring organizations that they are in safe hands. The future of the pandemic is still unpredictable. While its elimination is hopeful, it is still well worth the investment for many organizations to install the tools which minimize the risk of infection of COVID-19 - or any future infections. Clients are looking for certainty in an uncertain world and data-driven insights and real-time monitoring are ideal ways to provide this. However, the reassurance that comes with a strong working partnership will also be more important than ever. Communicating developments and what they mean for the client, as well as assuring them their priorities are understood can set a provider apart.
The impact of HVAC systems on the spread of the novel coronavirus has been a hot topic since the beginning of the pandemic. However, it is striking that, even given all the discussions and guidance, there is still a lot that we do not know. Vaguely speaking, we know that crowded spaces with poor ventilation and/or low humidity levels tend to promote virus spread that filtration can help to remove the virus, and that measures such as UV-C radiation can help to disinfect indoor air. But even those suggestions are far from definitive and may be undermined by future study. In general, we ‘think’ that HVAC systems are a factor in spreading the virus, but we are not sure. Air flow Obviously, because the coronavirus is new, much information about the relationship between HVAC and virus spread is based on studies that were carried out in previous years related to other germs, such as SARS-CoV and MERS-CoV, which are similar to SARS-CoV-2, the virus that causes COVID-19. But can this previous testing and studies really be extrapolated to apply to the new disease? The answer is that no one really knows; therefore, such information basically amounts to educated guesses. There have been some studies since the pandemic began about how HVAC and air flow impact disease spread, some of them in China. However, these studies involve smaller sample sizes and come with caveats, disclaimers, and fine print contained in footnotes about the limitations of the conclusions. Hypotheses are often formulated, but typically the authors have not conducted aerodynamic testing or used other techniques to confirm them. HVAC and the transmission of pathogens A rush to provide useful (if flawed) information is understandable in the midst of an emergency More study is needed, and more time is needed to complete those studies and expand our base of knowledge on this important subject. A rush to provide useful (if flawed) information is understandable in the midst of an emergency. Acting on imperfect information has likely saved thousands of lives. But that success does not diminish the need to pursue more detailed and accurate information. Those pursuits will likely extend years into the future and well past the aftermath of the pandemic. Studies are needed in specific areas to round out the knowledge base and prepare us to better understand the impact of HVAC on disease spread in the next pandemic. There are no clear answers, and the role of a building’s HVAC systems in transmission of pathogens requires more attention. Further areas of study Among other areas, we need studies to cover: Epidemiologic factors to measure the role of ventilation, recirculated air, and to adequately quantify ventilation rates Use of computer simulations to more accurately track the spread of fine-exhaled droplets. More robust examination of the direct role of HVAC in transmitting and removing viable viruses within respiratory droplets or short-range aerosols. More research by multi-disciplinary teams that include HVAC engineers, epidemiologists, virologists, infectious disease experts, and other experts working together. Broader studies should cover the fields of epidemiology, engineering and aerodynamics/aerobiology. More partnerships between building facilities management departments and those tasked with preventing infection. Will the pandemic change HVAC? The pandemic has impacted the HVAC market in many ways. As more of us spend time at home, we become more concerned about issues of air quality and indoor comfort. Some of the changes in our work-life patterns will likely be permanent, which will have a lasting impact on how office buildings are used – and how they are heated and cooled. It may be that the global pandemic changes the HVAC market for good, both challenging us to expand our technologies and providing opportunities to enhance our businesses. In the future, 2020 may become a pivotal date in the history of the HVAC market – a date after which nothing is ever quite the same. Establishing a sound scientific basis to direct the changing role of HVAC ‘after Covid’ will enable the industry to invest in safer technologies and innovative approaches to drive the future of the industry – and of the world.
The Wyss Institute at Harvard University has developed an evaporative cooling system that uses a specially coated ceramic to cool air without adding humidity. Researchers say the approach can yield more affordable and environmentally friendly air conditioning systems for the future. ‘cold-SNAP’ system The ‘cold-SNAP’ system uses a water-repellent nano-scale surface coating that is applied selectively to surfaces of a 3D-printed ceramic heat exchange. The result is much cooler buildings with less humidity. ‘cold-SNAP’ is short for cold superhydrophobic nano-architecture process. The invention uses evaporative cooling, which happens when hot air is put in contact with water. As the water evaporates, it cools the air but adds moisture. Use of the water-repellent coating separates the moisture from the cool air to provide an inexpensive source of cooler, dryer air that can cool a building in lieu of traditional air conditioners. Evaporative Cooling technology The hydrophobic coating is selectively applied to components that will manage the flow of dry air The approach is a union of old and new – combining ceramic, one of the oldest, cheapest and most widely available building materials, with the novel hydrophobic surface coating developed by Wyss Institute. Because ceramic is malleable, the heating exchange unit can be produced via extrusion or 3D printing of a single piece, with its shape adjusted to maximize surface area available for heat transfer and evaporation. The hydrophobic coating is selectively applied to components that will manage the flow of dry air. Variation on indirect evaporative cooling (IEC) systems The specialized coating separates incoming hot air from outgoing wet air, allowing the hot air to be cooled by circulating water without adding humidity to the inside of a building. ‘cold-SNAP’ is a variation on indirect evaporative cooling (IEC) systems, which use complex heat exchange units that make them difficult and expensive to manufacture. Researchers say the approach can create low-cost, efficient air-cooling units to meet the world’s increasing demand while using 75% less energy. The system can be up to four times more efficient than conventional air conditioners as measured by the coefficient of performance (COP), the ratio of cooling to required energy. ‘cold-SNAP’ was designed by a multi-disciplinary team of scientists and designers from the Wyss Institute’s Adaptive Material Technologies Platform, Harvard’s Graduate School of Design (GSD), and the Harvard Center for Green Buildings and Cities (HCGBC). Integration into evaporative cooling systems The new technology could be integrated into existing evaporative cooling systems and sold as environmentally friendly air conditioners in a variety of climate zones. It could even be manufactured into the facades of buildings, thus cooling the space within, using only the energy needed to pump water to the system. With global warming causing a rise in the Earth’s average temperature, worldwide demand for air conditioning systems that do not contribute to that climate change increasingly will be in demand. A growing middle class throughout the world is also contributing to demand. No humidity added to the air ‘cold-SNAP’ does not add humidity to the air and works well in humid, tropical climates, as well as dry, hot climates Because ‘cold-SNAP’ does not add humidity to the air, it works well in humid, tropical climates (where it is sorely needed) as well as in dry, hot climates like the Middle East. Traditional electric air conditioners use mechanical vapor compression to convert a chemical refrigerant back and forth between its liquid and vapor forms, absorbing heat during vaporization and then removing moisture during condensation. Traditional systems use a large amount of energy to cycle the refrigerant, which increases costs, not to mention the refrigerants contribute to global warming. Historically, the environmental impact of such systems was a hidden cost that was not considered. Wyss Institute Validation Project In 2019, ‘cold-SNAP’ was named a Wyss Institute Validation Project, which puts it on track to become commercialized. The validation program seeks to ‘de-risk' technologies and demonstrate that they can be scaled up for commercialization. The Wyss Institute for Biologically Inspired Engineering at Harvard University emulates Nature’s design principles to engineer new, ‘bio-inspired’ materials and devices with high-impact applications in healthcare, manufacturing, robotics, energy, and sustainable architecture. The cross-disciplinary faculty, technical staff, students, and fellows undertake high-risk research and technology development.
The California Air Resources Board (CARB) is moving forward with rulemaking that sets limits and deadlines to decrease the use of refrigerants with global warming potential (GWP) in the commercial refrigeration market and in the residential and commercial stationary air conditioning equipment markets. California regulations are widely expected to influence the direction of other states seeking to regulate GWP of refrigerants. Declining to delay planned deadlines because of the novel coronavirus pandemic, CARB is proposing a GWP limit of 150 for new stationary refrigeration systems that contain more than 50 pounds of refrigerant, irrespective of end use, beginning on January 1, 2022. GWP Of Air Conditioning Systems California State Fire Marshal currently does not allow use of mildly flammable refrigerants in the state’s building codes For residential and commercial stationary air conditioning systems, the proposed new rule will take effect on January 1, 2023, and will include a GWP limit of 750. CARB held a public workshop in July to discuss the proposals. There is another challenge of implementing the limits. The alternative materials that enable compliance include lower-GWP A2L refrigerants that are mildly flammable; however, the California State Fire Marshal currently does not allow use of mildly flammable refrigerants in the state’s building codes. Presumably, the building codes will be updated in time to allow use of A2L refrigerants as an alternative to meet the limits, but the uncertainty makes it harder to plan ahead. Washington state has already revised its state building codes to allow the use of A2L, and other states are in the process of doing the same. VRF Manufacturers Concerns The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) industry group has been in discussions with CARB about anticipated industry and supply chain compliance challenges caused by COVID-19 disruptions, and because California building codes do not yet reference required safety standards. At the public workshop, AHRI proposed January 1, 2025, transition date for 750 GWP for newly manufactured air conditioning equipment, but CARB did not comment on the proposal. Manufacturers of variable refrigerant flow (VRF) systems have also expressed concerns with meeting the compliance deadlines. However, the current 2023 deadline coincides with the implementation of new U.S. Department of Energy efficiency requirements for residential central air conditioner and air-source heat pump systems. This timing allows manufacturers to design systems to meet both the CARB and DOE requirements at the same time, rather than having to redesign systems twice. Destructive Measure of climate pollutants Global warming potential (GWP) is a measure of how destructive a climate pollutant is, compared with carbon dioxide Global warming potential (GWP) is a measure of how destructive a climate pollutant is, compared with carbon dioxide (CO2), which is assigned a value of 1. GWPs are also used to define the impact greenhouse gases will have on global warming over various time periods; a time horizon of 100 years is used by CARB, which maintains a list of GWPs for common refrigerants. Driving the new rulemaking in California are regulations passed in 2016 that commit California to reduce HFC emissions in the state by 40% below 2013 levels by 2030. Release for public comment By enacting the 750 GWP limit for new stationary air conditioners in 2023, CARB projects a reduction of 2.3 million metric tons in CO2 equivalents of annual emissions in 2030. That is almost a fourth of the progress needed to achieve the target and equates to removing about half a million passenger cars from California roadways each year from 2023 to 2040. A finalized “notice package,” which includes details of the new limits and deadlines, will be released for a 45-day public comment period on October 23, 2020, with the comment period ending right before the CARB’s board hearing in mid-December, when the board could approve the package.
Thermo King® customer Bottomley Enterprises greens up the holidays for millions of people across the United States each year. For many people, the holidays are simply not complete without a traditional tree, wreath, garland, swag, or some type of tabletop greenery – the fresh evergreen smells are often that final touch that make gatherings with family and friends memorable. And while millions flock to their local box stores for these holiday treasures, the odds are good that the products originated from the Blue Ridge Mountains and were delivered with love by Thermo King Customer Bottomley Enterprises. Producing exceptional quality “Our farm ships to large box retailers, the who’s who of retailers,” said Ken Kaelin, president of Bottomley Enterprises, the transportation arm for Bottomley Evergreens and Farms, which has been producing exceptional quality and service for nearly 30 years. What started out as a small family farming business in the hills of North Carolina has grown to produce a large variety of vegetables – think cabbage, corn, cilantro, collards, sweetcorn, pumpkins, green beans, and more, that feed consumers throughout the U.S. It also became one of the largest suppliers of holiday greenery in the eastern United States. The farming business led to the creation of Bottomley Enterprises in 2004 as founder Mitchell Bottomley fulfilled his dream of owning his own trucking company. While the businesses operate separately, Bottomley Enterprises still hauls the farm’s products. Home-Grown products Bottomley has depended on Thermo King refrigeration units to preserve the quality of the home-grown products From its beginning, Bottomley Enterprises has depended on Thermo King refrigeration units to preserve the quality of the home-grown products it transports. “The company started with just a couple tractors and trailers. Today, we are running a fleet of 70 tractors and 120 refrigerated trailers – all with Thermo King Precedent® S-600 units and a few legacy units that are used at the farm,” said Ken. “That number represents 40 percent growth within the past 15 months alone. Our trucking arm has enjoyed fast growth through our great culture, solid customer base and dedicated employees who understand that service is everything. All of this has really allowed for an exciting evolution for our companies.” Remote setting control Indeed, service is king for the Bottomley businesses, “And that’s a big reason why we have always chosen Thermo King to protect our products,” said Mitchell, who owns the company with his mother, Martha. “We are proud Thermo King users – it’s the only unit we have because we can depend on them. We love our Thermo King units.” The company not only depends on the refrigeration capacity of the units but also the telematics technology built into each unit. “We count on the TracKing® telematics,” said Ken. “The scrutiny of food safety and the ability to have visibility throughout the supply chain is like quenching a thirst for shippers. It helps us keep insurance and liability costs down. It offers remote setting control. It helps us track each load. It’s essential these days.” Keeping products safe Thermo King Central Carolinas also takes care of our reefer service work" Beyond the product is the service Bottomley receives from its home dealer Thermo King Central Carolinas and the entire Thermo King dealer network. “The partnership we get from Ben Cox, our service representative, is outstanding – he really is an extension of our employee team. He helps us manage our equipment and maintenance needs, and he provides our drivers with the product and operational information they need to run the unit efficiently – and keep our products safe.” “Thermo King Central Carolinas also takes care of our reefer service work, ensuring the equipment is tuned up and ready to go – this is wildly helpful to us. And if service is needed when our 120 team drivers are out on the road, we have an entire network to call on – that is added peace of mind,” said Ken. Refrigerated transport business Peace of mind is particularly important this time of year, when so many are depending on a fresh selection of trees and greenery at their local stores so they can decorate their homes with traditional holiday décor. The Bottomley family is poised to continue delivering for the long haul having recently opened a 33,000 square foot new trucking terminal in Mount Airy, North Carolina, that will accommodate many years of growth and create new jobs. “They have built a legacy – in both their farming business and the long-haul refrigerated transport business, and it truly is a pleasure to partner with them and see their continued successful growth,” said Ben.
