The European Commission and Öko-Recherche recently presented the preliminary findings of the F-Gas review study. The study notably models the degree to which F-Gases could be substituted in RACHP equipment until 2050. Eurovent considers the substitution scenarios unrealistic and has expressed skepticism about the modeling assumptions used by the study consultant. Review of the study The study notably foresees that hydrocarbons could be used in up to 90% of small heat pumps as of 2025, and in all large split air conditioners and VRFs as of 2030. Eurovent data on the current market penetration of non-fluorinated refrigerants show that this modeling is completely unrealistic, raising questions on the assumptions that underpin it. Review study would form the basis for potential amendments to the F-Gas Regulation Moreover, the study consultant appears not to have considered the regulatory and standardization barriers which still significantly prevent flammable refrigerants from being used in heating and air conditioning equipment in many EU countries, unlike for the commercial refrigeration sector where these restrictions have already been eased. These preliminary results are worrisome because the review study would form the basis for potential amendments to the F-Gas Regulation, which could result in unfeasible requirements. Authority Comments Francesco Scuderi, Deputy Secretary-General of Eurovent: “Facilitating the transition to lower-GWP refrigerants is one of Eurovent’s core ambitions and, in this context, we have always been big advocates of the F-Gas Regulation. With the review ongoing, we have been working closely together with European Commission and the study consultants to see how to further improve the current framework. That said, we are puzzled by the preliminary findings of the review study." "Except for the commercial refrigeration sector, where non-fluorinated refrigerants already represent a preponderance of new products brought to the market, we see no realistic pathway from the current situation to the substitution milestones that were conjured up by the models. The study puts the global competitiveness of our industry on shaky grounds, which would be a big win for fossil fuels.” Concerns Eurovent has submitted its concerns to the European Commission and study consultants and is working with partner associations to mobilize a common industry response. The European Commission is expected to publish its proposed amended F-Gas Regulation still in 2021, which would be followed by an F-Gas Consultation Forum meeting 6 weeks after.
No matter how brief, power outages inevitably impact productivity. The good news is it is now easier to keep critical processes running reliably. Induction motors controlled by high-power VLT® drives can recover faster from mains drop-out, thanks to improvements in the flying start feature. Function The flying start feature kicks in to catch a motor that is spinning freely due to a mains drop-out or windmilling. This function is especially relevant for centrifuges and fans. Flying start allows the driver to synchronize with an operating motor rotating at up to full speed in either direction. This prevents trips due to overcurrent draw. It also minimizes mechanical stress on the system since there is no abrupt change in motor speed when the drive re-starts. Features Use the new improved flying start for induction motors running at speeds up to 132 Hz, with VLT® AutomationDrive FC 302, VLT® AQUA Drive FC 202, VLT® Refrigeration Drive FC 103, or VLT® HVAC Drive FC 102 running in VVC+ mode. The new flying start is also active in VLT® AutomationDrive FC 302 when running in flux mode. For induction motors running at speeds above 132 Hz, the flying start function will operate as before. Benefits of the improved flying start include: Reliable catch of the motor Up to 4 times faster recovery Minimal mechanical stress on the system
The ongoing COVID-19 outbreak already forced the postponement of the upcoming EUROVENTSUMMIT from September 2020 to October 2021. After carefully evaluating the situation, the organizers have decided that the Summit will be further postponed to 2022. Although postponed to 2022, the next edition of the EUROVENTSUMMIT is still scheduled to take place in Antalya, Turkey. Concrete dates will be announced later this year. Naci Sahin, outgoing Eurovent President and representative of the local Member Association and Summit co-organizer ISKID, stated: “While this was not an easy decision to make, the health and safety of the participants is our number one priority. We believe that moving the event to 2022 is an opportunity rather than a setback. Seeing the increasing vaccination rates and the world slowly waking up and going back to normal, we are hopeful that further postponing the event will allow us to host a full-scale EUROVENTSUMMIT with all its features and perks.”
Hitachi has announced the release of its new line of mini-split systems that employ the latest technologies, in order to maximize comfort and ensure healthy indoor air. Key features of the new mini-split systems include: An intelligent human sensor system monitors and responds to the environment, to provide continuous comfort. Temperature and humidity levels are controlled, when set to dehumidification mode. Innovative FrostWash technology ensures indoor air is fresh and clean, by eliminating dust, bacteria, and mold. User-friendly airCloud Home app puts control in the palm of the homeowner’s hand and is fully compatible with Amazon Alexa and Google Assistant, enabling voice control when hands are full. Vector DC Inverter Technology Hitachi mini splits feature Vector DC inverters, in order to achieve high performance energy efficiency Hitachi mini splits feature Vector DC inverters, in order to achieve high performance energy efficiency. These inverters cool with maximum capacity at startup, then automatically slow down and operate at minimum capacity, to maintain room temperature at a comfortable level. This reduces energy consumption by up to 62%, when compared to non-inverter levels. A special microchip that is preloaded with the compressor’s data will constantly monitor its operation, while running. This helps the unit to adjust the amount of energy needed, by sending accurate instructions to the compressor, in order to achieve the optimal rotation speed and avoid unnecessary power waste. Easy installation with cooling-only lock function Hitachi mini splits are flexible, easy to install, and offer a wide range of sizes, to make it easy to specify the perfect solution for any project. A cooling-only lock function prohibits heat, when used in ambient cooling applications. Single-zone systems are available in 115V or 208/230V with capacities ranging from .75 to 3 tons. Multi-zone systems can accommodate up to 5 zones with 208/230V and capacities ranging from 1.5 to 3.5 tons.
Two variations of Shower Heat Recovery Unit (SHRU) have been unveiled, as the Baxi Assure range expands to provide even more energy efficient heating and hot water accessory choice for new build housing professionals. Developed as part of a wider portfolio of Baxi Heating’s Assure products and services that are intended to support developers at every project stage, the Baxi Assure SHRU range can offer up to 66.6% heat recovery and up to 8% SAP benefits. Baxi Assure SHRU units Baxi Assure SHRU units are designed to recover heat from waste bath or shower water via the in-built heat exchanger These fit and forget Baxi Assure SHRU units are designed to recover heat from waste bath or shower water via the in-built heat exchanger, which is then transferred to the mains cold water feed to the boiler. This places less energy load on the boiler to raise the temperature to the desired level of comfort. Providing the maximum efficiencies, the Baxi Assure SHRU vertical unit is available with a twin inlet, enabling it to recycle heat from two waste water pipes within the same property. Energy efficient heating and hot water products Nick Wilson, the Commercial & Marketing Director at Baxi Heating, stated, “Our range of energy efficient heating and hot water products and accessories is key to our complete home service proposition, and we are proud to offer the SHRU as part of this.” Nick Wilson adds, “With an impressive energy uplift, new build developers can trust the SHRU to deliver on SAP performance and also take advantage of Baxi Assure’s end to end project solutions, including advice from qualified Baxi Assure SAP assessors to help boost efficiency and a Baxi Design service for accurate sizing and specification.” Project Hub Projects benefit further from support at every stage from a dedicated team of specification managers, bespoke product training, and a Project Hub to manage project product registrations, in addition to technical support and advice from installation to legislation.
The education field was faced with multiple challenges this past year. Not only did the COVID-19 pandemic bring the necessity of online learning, but it has also brought up necessary changes to physical schools and universities, when reopening time arrives. The health and safety of students, staff, and faculty has become a priority for directors of school operations, who have been working to properly adapt school facilities to this new reality we are facing. Ensuring health and safety of students Besides safety measures like the addition of hand sanitizers, reinforcing the use of masks and social distancing, these professionals were faced with an even bigger and more important issue: ventilation and airflow indoors. School facilities have many unique features that increase the concerns regarding indoor air quality. Occupants are usually very close together, considering that school buildings have four times as many occupants as office buildings for the same amount of floor space (EPA). Variety of pollutant sources According to the WHO, the virus can also spread in poorly ventilated and/or crowded indoor settings Other issues include tight budgets, the presence of a variety of pollutant sources (including specialty classrooms, like art, gyms, and labs), concentrated diesel exhaust exposure due to school buses in the property, and a large amount of heating and ventilation systems that may cause an added strain on maintenance staff. On top of that, schools usually have to worry about child safety issues, concerned parents, and wellbeing of faculty and staff. According to the World Health Organization (WHO), the virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time and aerosols particles tend to be suspended in the air, which leads to the importance of indoor air quality in classrooms. Importance of natural ventilation and HVAC systems Natural ventilation and HVAC systems are the basic methods to bring clean air indoors, however, schools that rely only on these methods of ventilation need to be aware of their potential limitations. HVAC systems, for example, should have regular maintenance checks and filter changes, in cases where the system is less sophisticated, schools need to add new forms of air purification to effectively mitigate airborne pathogens. Studies showing quality of air in US schools Studies have shown that low-standards HVAC ventilation systems may contribute to airborne diseases transmission due to low air exchanges rates, poor maintenance and lack of high-efficiency filters. For this reason, portable air cleaners are becoming more and more popular to create a healthy learning environment. EnviroKlenz, an indoor air quality company, conducted real-life setting studies to show the quality of the air in schools in different areas of the United States. The study measured the amount of particulate matter in classrooms, with and without the use of additional portable filtration systems, which allowed for comparison and analysis of the benefits a portable air cleaner can provide. National EPA standards for indoor particulate matter The study also compared the current data to the national EPA standards for indoor particulate matter (PM), in order to evaluate the performance of the EnviroKlenz Air System Plus. The IAQ meters focused on PM1, which is about 1 micrometer in size (70 times smaller than the diameter of human hair!). The systems ran in operational educational environments, with daily schedules being carried out as usual and results can be seen below. School directors of operations also must pay attention to the different technologies available in portable air cleaners. With the growth of the industry, new emerging technologies have come up, and there’s still lack of third-party testing to prove their efficacy. Other technologies, like carbon filters, do not work against airborne pathogens and may release harmful byproducts back into the environment. EnviroKlenz Air System Plus EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture pathogens, is at 99.9% efficiency The EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture virus, bacteria and other harmful pathogens, is at 99.9% efficiency and is complemented by a medical-grade HEPA filter and UV-C lights, was also tested against a carbon-based air cleaner in a classroom. As shown below, the carbon system struggled to keep consistency, with peaks and valleys throughout the day. Meanwhile, when the EnviroKlenz Air System Plus was turned on, the PM1 levels were steadily low for over 4 consecutive days. Deploying portable air cleaners in classrooms Adding a portable air cleaner to classrooms and common areas will increase air exchange rate and mitigation efforts, but the long-term benefits go beyond the pandemic. Studies have shown that good indoor air and ventilation rates are directly linked with students’ academic achievements and can increase performance. High CO2 levels in a school environment are also associated with lower average annual attendance and worse individual test performance. Other long-term benefits include reducing symptoms of those who suffer from respiratory diseases and creating a favorable environment not only for students, but also for teachers and staff; while bringing a sense of comfort and well-being to parents and the community. Combined benefits of air filtration, ventilation, and purification “When we’re operating more normally, maybe we’ll be able to cut down on some of the traditional flu-peaks that schools have, or cold peaks, that kids just bring into school, by managing the airborne virus and bacteria quality,” said Peter Twadell, Head of School at Birches School in the US, and an EnviroKlenz Customer. School officials need to consider the combined benefits offered by filtration, ventilation, and purification methods to create the healthiest environment possible. Thinking in a pandemic-conscious mindset, air quality has gained the recognition it deserves in creating a proper and healthy learning environment.
Do HVAC systems help with the spread of COVID-19? No one is entirely sure, but it seems very likely. Especially in the case of enclosed indoor spaces. As soon as the COVID-19 pandemic began, fingers pointed to air-conditioning systems as culprits, and scientists now believe a super-spreader event traced back to a restaurant in Guangzhou, in China, which could have started with an asymptomatic person who just happened to cough close to an HVAC fan. Scientists also believe something similar happened on the Diamond Princess cruise ship, which made headlines over the world, in February 2020. Especially because cruise ships have elaborate inter-connected HVAC systems, which could have aided the coronavirus as it ripped through the cruise population. HVAC systems Role in COVID-19 spread And because air-conditioning units typically function indoors, and because the coronavirus (COVID-19 virus) can float about for a little while on respiratory droplets in the air, it should be no surprise at all that HVAC units have come under scrutiny. In response to this, over the last year, the REHVA (European Federation of Heating and Ventilation Engineers) group actually set out guidelines on what to do, in order to make HVAC units safer. Actually, they went further than that, because on the contrary, properly configured air-conditioning units can actually help to fight the coronavirus, rather than aid its spread. How AC units can limit viral transmission By making sure there is a fast and constant exchange of air, AC units can actually wash away virus particles Despite the apparent doom that HVAC units can kick start super-spreader events, the answer is not to do away with air-conditioning systems. In fact, REHVA recommends the opposite. Instead, what we actually need to do is to reconfigure our AC units so that they can stop coronavirus particles from loitering about in the air, and then settling down. When virus particles ‘settle’ on a surface, they can be infectious for a time. The technical term for this is a ‘fomite’ and an area that is infectious to touch. By adjusting the settings on AC units to increase the amount of outside air they pull in, and the rate to which this fresh air is distributed indoors, we can make indoor environments much safer. By making sure there is a fast and constant exchange of air, AC units can actually wash away virus particles and prevent fomites from occurring. What about just opening the windows? Before modern HVAC units, there was, of course, the humble open window. And sure, open windows is a great way to make sure that air from the inside is quickly and constantly being exchanged with the air from outside. But as we all know, opening the windows is seldom the ideal choice. For example, it isn’t desirable in cold or in air-polluted or noise-polluted spaces. Open windows can even be a hazard if there is a risk of injury or falling. If you can work in an environment with open windows in a way that’s feasible and manageable, that’s great. They will likely offer similar protection against lingering coronavirus particles. But even if you can, the evidence suggests that a properly configured HVAC system is still safer (not to mention more comfortable, given their ability to regulate temperature) than the age-old open window option. AC units with high-efficiency particulate air filters Arguably the most proficient AC units today are those equipped with high-efficiency particulate air (or HEPA) filters. Although, you will struggle to find any outside of surgical theatres and airplanes, where getting the right amount of air exchange is primarily a health and safety issue and not just an issue of comfort. But as the pandemic has revealed to us, having better optimized HVAC units in public indoor spaces is a health and safety issue. With that being said, could HEPA filters become the norm throughout major public indoor spaces? HEPA filters HEPA filters are so reliable because they are made up of thousands of layers that trap all types of particles HEPA filters are so reliable because they are made up of thousands of layers that trap all types of particles, from dust to viruses. And they operate with an astonishing speed, being able to completely turn over a room’s air up to 30 times per hour. It would almost certainly make sense for HEPA filters to at least be considered for widespread use, but there are some technical issues to work out before their deployment becomes feasible. Cost aside, these filters can cause ‘dragging’ when attached to traditional AC units, among other issues. But if we are serious about tackling all forms of viruses, including influenza which hospitalizes and kills thousands every year, perhaps the widespread deployment of HEPA filters should be at least thought about in our approach to the ‘new normal’. Protecting people with proper air conditioning Whatever the fate of the HEPA filters, we do not have to sit around and wait for a revolution in the HVAC units to keep the general public safe. We can do that right now by equipping and configuring our current systems to properly exchange the rate of air in indoor spaces — to blow away lingering particles and keep surfaces free from fomites. Fortunately for us, the COVID-19 virus finds it hard to spread outdoors. But that means almost all of the spreading must happen indoors. So, it is crucial that we do all we can from an HVAC perspective to limit the spread of the coronavirus, and indeed all the other infections (including flu), which collectively can infect and hospitalize thousands of people every year. New infectious diseases emerge, and old ones come and go all the time. With the guidelines that REHVA has put together and some vigilance, our actions could indirectly save many people from falling ill every year. In summary, it’s not rocket science. To make an indoor area safer from the coronavirus, turn your AC unit up. Blow away the germs and stop them from settling down with a frequent exchange of air at all times.
It’s no secret that climate change is one of the most pressing concerns facing our planet. We must act collectively on behalf of future generations to enact the change that will help us to avoid a climate catastrophe; and not least the HVAC industry, which has been, and remains, a major contributor to atmospheric greenhouse gases and global warming. In 2015, the UK Government, along with 196 parties entered the legally binding international treaty on climate change, which was adopted at COP 21 in Paris. For the first time in history, all nations committed to undertake the necessary, ambitious steps to combat climate change. Significant environmental milestone Whilst this was clearly a significant environmental milestone, how realistic is the 2030 deadline for zero Global Warming Potential (GWP), from the HVAC industry’s viewpoint? The refrigeration, air conditioning and heat pump (RACHP) sector is presently the largest of the F-gas emitting sectors. The RACHP sector is in fact the UK’s main user as well as emitter of hydrofluorocarbons (HFCs). HFCs are now the main refrigerants used in a broad range of RACHP applications Since the phasing-out of ozone-depleting refrigerants (CFCs and HCFCs), HFCs are now the main refrigerants used in a broad range of RACHP applications, such as commercial refrigeration and air conditioning. It is therefore unsurprising that the spotlight has fallen on the RACHP sector. However, the EU F-Gas Regulation, which was introduced in 2014, is helping to reshape the sector, and lowering carbon emissions. The regulation stipulates: A 79% cut in the GWP weighted quantity of HFCs that can be sold in the EU by 2030. Several bans which restrict the refrigerants that can be used in specific types of new RACHP equipment. Bans on servicing R-404A systems in medium and large sized supermarket and industrial systems as of 2020. New rules on leak prevention and mandatory leak testing. Industrial refrigeration equipment In response to these new rules, many operating in the RACHP sector have introduced lower-GWP equipment. For instance, in the small-medium building air conditioning market, ultra-low GWP (<10) equipment is now an available option. Whilst the sector is committed to lowering its carbon footprint and has made good progress to date, the target of achieving a zero GWP by 2030 seems slightly unrealistic for a number of reasons. Whilst there is continuous improvement to RACHP equipment, an issue is the long life span of many products. For instance, some industrial refrigeration equipment typically has a life span of 30+ years; which means that approximately half of the industrial refrigeration equipment currently in use could remain so until 2030 and beyond. Reducing environmental impact The replacement of existing equipment is constrained by the equipment’s lifecycle The replacement of existing equipment is constrained by the equipment’s lifecycle, therefore, assuming that there is no premature retirement or retrofitting of the existing equipment, then implementing new alternatives could take decades, potentially. In terms of reducing environmental impact, the industry is reliant on the development of new technology, and manufacturers implementing that technology in the design of new equipment, to provide low-GWP alternatives. We are constrained by the rate at which manufacturers can bring these new products to market. The RACHP sector is also complex and contains an array of sub-sectors. The rate of progress in developing products with lower GWP varies considerably by sub-sector. For example, in the refrigeration sector, in commercial and retail applications where condensing units are used, the progress in lowering GWP is proving to be very slow. Variable refrigerant flow However, when it comes to small-sealed units, on the contrary, an impressive range of new low-GWP products have been brought to market. We can see a similar story in the air conditioning sector, where progress on lowering GWP is rather slow when it comes to large variable refrigerant flow (VRF) and large-ducted units; whereas for water chillers, they are making excellent progress. GWP rating may not be the key consideration in choosing a suitable product In the RACHP sector, there isn’t a one-size-fits-all product. Different equipment is required for different applications. For example, where RACHP systems are located in areas with public occupancy (e.g., retailers), public safety becomes a key concern, and would therefore limit our product choice, as well as the refrigerant type which could be used. Therefore, GWP rating may not be the key consideration in choosing a suitable product, it’s about selecting the right equipment for the application. Providing thermodynamic properties When it comes to RACHP equipment, there is a huge variance in temperature levels. In refrigeration, equipment temperature ranges from 0°C to 5°C for chilled food, and -15°C to -40°C for frozen food. In air-conditioning, the temperature typically ranges between 10°C to 20°Cii. These significant variations in temperature levels require a range of refrigerants to be available, to provide the thermodynamic properties to suit the specific application. It is worth noting here that not all have low GWP ratings. Despite stating that some of the targets are unrealistic, I do however believe that as an industry, we can collectively work together to make a difference to our planet. Maximum gas recovery Here are a few practical ways we can help to lower our carbon emissions: Use low GWP alternative refrigerants in new equipment – This is the key to success in the long term. As I explained previously, the long lifecycle of some of the equipment means that it will potentially be many years before the existing repository of HFCs is completely obsolete. However, it is a realistic goal that by 2050, the current generation of high-GWP HFCs could be replaced with low-GWP alternatives. Recover F-Gases from equipment - Old equipment reaching end-of-life contains HFCs. It is illegal to vent these HFCs into the atmosphere. The F-Gas Regulation has a mandatory requirement for the old HFC to be recovered. This refrigerant should be reprocessed, recycled and reused. Although this does not directly reduce F-Gas emissions in the short term, it does encourage maximum gas recovery. Leakage-Detection systems Reduce the usage of HFCs in existing equipment - Interestingly, a large proportion of total HFC consumption is actually to top-up leaks from existing equipment. If we could make advances in the area of leak-prevention, through further development of leakage-detection systems, this would reduce the volumes of HFC inadvertently entering the atmosphere. I’d also advise businesses to regularly undertake leak testing and to keep records. The world needs the entire HVAC industry to lead and drive the change required to reduce our carbon footprint. We must champion the solutions for the climate change crisis. Equally, businesses have a responsibility to ensure they remain F-Gas compliant and that their air conditioning and refrigeration systems continue to work at peak efficiency.
Incorporating cool and dry outdoor air into commercial HVAC systems can save money and energy, while causing less wear-and-tear on cooling systems. An economizer is a device that works alongside rooftop HVAC systems to augment the system with outdoor air, in order to provide what has become known as ‘free cooling’. Economizers Economizers introduce low-temperature or low-enthalpy outdoor air into a building to reduce or eliminate mechanical cooling, depending on outdoor air conditions. [Enthalpy is a thermodynamic quantity equivalent to the total heat content of a system.] An economizer evaluates the temperature (and sometimes humidity) levels of outdoor air. A combination of logic controllers and sensors both assess the right level of outside air to bring in and operate internal dampers to control how much air is pulled in, re-circulated, and exhausted from a building. Rather than relying solely on a building’s cooling system, the system leverages cool outside air to accomplish the same task. Free Cooling When outside air is cooler than re-circulated air, using more outside air is more energy efficient When outside air is cooler than re-circulated air, using more outside air is more energy efficient. When outside air is sufficiently cool and dry, no additional air conditioning is needed, hence the term ‘free cooling’. By minimizing the operation of an A/C unit, economizers can prolong the life of a system, reduce costs, and minimize maintenance with fewer breakdowns. Enhanced ventilation Extra ventilation is another benefit of economizers, which is important in the era of COVID-19. An economizer can improve overall air quality by bringing in the fresh air and exhausting the building’s stale air. Even in older buildings that were not designed with ventilation in mind, economizers can improve air quality. Fresh air can keep employees healthier and minimize an employer’s cost of sick days because of air pollutants. There are three types of economizers: Dry bulb, which evaluates the difference between the temperatures of indoor and outdoor air, but does not consider humidity. Web bulb or Single Enthalpy, which evaluate both air temperature and humidity. They are the most popular option. Differential Enthalpy, which uses multiple sensors to measure temperature and humidity of return air, as well as the outside air, a popular option for more complex scenarios. Minimizing total building energy consumption Energy costs are a big advantage of economizers, helping to minimize total building energy consumption, 45% of which is accounted for by the HVAC system. The use of an economizer provides up to 45% greater efficiency in cooling loads than existing HVAC operations, according to researchers. Climate conditions are a significant factor affecting the energy-saving impact of air economizers. Researchers evaluated the energy-saving potential of economizer systems in six climate zones, concluding that energy savings in hot-humid summer climate zones were 10% higher compared to cool-dry summer zones. Good controls, valves, and dampers are needed to ensure optimal operation of economizers, and maintenance is also critical.
The cruise ship industry has cracked the code on keeping passengers and crew safe from the coronavirus (COVID-19) spread, including changes to on-board HVAC systems to use more outside air and to filter out particles as small as the novel coronavirus. The industry, which voluntarily suspended worldwide operations at the beginning of the COVID-19 pandemic, under the guidance of international and national health authorities, plans to resume worldwide operations fully later in 2021. Health protocols to mitigate COVID-19 risk The cruise ship industry resumed sailing in parts of Europe, Asia and South Pacific in July 2020 The cruise ship industry resumed sailing in parts of Europe, Asia and South Pacific in July 2020 and completed more than 200 sailings by the end of 2020. The success of these early sailings demonstrated the effectiveness of new protocols to mitigate risk of COVID-19 among passengers, crews and at destinations. The industry will resume operation in the United States, Canada, Mexico, the Caribbean and elsewhere in 2021. Cruise operators, such as Royal Caribbean, have implemented new HVAC systems as part of the protocols. Supplying 100% fresh and filtered air Royal Caribbean says its HVAC system now continuously supplies 100% fresh and filtered air from outdoors to all indoor spaces. There is a total air change up to 12 times an hour in staterooms and about 15 changes per hour in large public spaces. Fan coil units provide an extra layer of protection in local spaces, such as public venues and staterooms, continuously scrubbing the air of pathogens and using MERV 13 filters to capture aerosols between 1.0 and 3.0 microns with 90% efficacy. Bio-aerosol assessment study Royal Caribbean participated in a bio-aerosol assessment of its ‘Oasis of the Seas’ ship by the University of Nebraska Medical Center. The study involved releasing billions of 1-micron aerosol-sized microspheres, each containing a uniquely DNA-barcoded inert virus surrogate, at pre-selected spaces throughout the ship. The test was intended to determine the efficiency and effectiveness of the vessel’s indoor air management strategies and to understand spread of aerosols through the HVAC system. Low risk of cross-contamination of air Testing results led to minimal changes, such as ensuring air exchanges are close to hospital standards and using MERV 13 filters Over a week aboard the Oasis of the Seas, scientists released billions of the individually tagged microspheres and then tracked where they went and how long they lingered in the air, and on surfaces. Testing results led to minimal changes, such as ensuring air exchanges are close to hospital standards and using MERV 13 filters. The study confirmed that cross-contamination of air between adjacent public spaces is extremely low and undetectable in most test cases. Royal Caribbean’s Healthy Sail Center determined seven important elements the cruise line can do to manage indoor air and keep it clean. These elements include: Enhanced filtration to the highest level possible Optimize airflow patterns Use negative pressurization in isolation rooms Minimize unfiltered, re-circulated air Increase number of air changes per hour Use portable HEPA filters in congregate areas Maximize outdoor functions and physical distancing Facilitating return to operation of cruise ships At the start of the COVID-19 pandemic, between March 1 and July 10, 2020, the Centers for Disease Control and Prevention (CDC) discovered nearly 3,000 cases of COVID -19 or suspected COVID-19 infections and 34 deaths across 123 cruise ships. In October 2020, the CDC lifted its no-sail order, laying out guidelines for big-ship cruising to resume operations in U.S. waters. The Cruise Lines International Association (CIA), which represents 95% of the cruise ship industry, has said its members will return when the time is right and that timing will be based on factors, including input from scientists and medical experts. Cruise companies also have new technologies available to them now. For example, the Italian company, Integra provides an air sanitizer that uses an odorless disinfectant to combat airborne illnesses. It can be installed in 15 minutes.
The connectivity of the Internet of Things (IoT) provides new tools to monitor the well-being of an HVAC system, to provide instant alerts to any operational problems and even to predict when problems are likely to occur. Being alert to early warning signs of a problem enables deployment of less-expensive fixes before the problem escalates. predictive analytics Remote monitoring and predictive analytics of HVAC systems have been even more valuable during the time of the COVID-19 pandemic, when many buildings have been empty. Potential problems come to light faster and can be repaired less expensively, even if no one is on site to complain about an obvious failure. When buildings are occupied, the customer experience is even better and operational and maintenance costs are lower. These capabilities can be integrated with other Building Management Systems (BMS) to provide a broad-based view of various operating systems throughout a facility. In addition to early warning of system failure, system monitoring can also provide new and smarter tools for keeping track of indoor air quality (IAQ) and to minimize energy consumption. Artificial Intelligence (AI) in the Cloud Predictive and preventive maintenance are key to ensuring that issues are addressed before they can do damage Sensors and other devices deployed in today’s systems provide hundreds of new data points that are interpreted by Artificial Intelligence (AI) operating in the Cloud. The combination provides detailed and useful insights into how a system operates over time, thus maximizing operation and minimizing energy usage in ways that are more in tune with environmental needs than ever before. Predictive and preventive maintenance are key to ensuring that issues are addressed before they can do serious damage, according to Johnson Controls (JCI). Smart data analysis enables more informed and smarter decisions, thus resulting in reduced maintenance costs, improved efficiency, and overall peace of mind, as per the company. Connected Services Johnson Controls (JCI) offers Connected Services to provide customers with constant equipment monitoring and data analysis, and uses the data proactively to identify faults before they occur and even predict future optimization opportunities and efficiencies. Integration of both equipment and software into a single system makes it more than a sum of its parts. Johnson Controls lists some key benefits of implementing an integrated system: Identify energy savings opportunities. Regular reports on the operational performance provide insights on areas of improvement. Extend asset life. Identifying and managing required maintenance helps to extend equipment lifespan. Minimize repair costs. Faults mitigated at an early stage avoid major failures. Reduced emissions. Operational performance reporting enables chillers to operate in the most efficient range. Monitoring system performance Emerson’s Sensi Predict line goes to the root of HVAC systems to monitor performance, identify issues and alert contractors and home owners to the efficiency, energy usage and overall performance of HVAC units. An internal Emerson study reviewed the most common HVAC failures and determined that installing the technology could detect up to 80% of failures in these areas, before a home owner suffers system outage. Real-time and connected systems use a variety of sensors that constantly monitor the functioning of an HVAC system. Connectivity puts more information than ever at the fingertips of HVAC professionals, making them more responsive than ever to customer needs.
A large manufacturer of steel cables from Detroit, Michigan contacted Wattco with a problem that the cables they manufactured were corroding in their warehouse and needed a solution to prevent this from happening. Steel products that often sat in inventory for long periods of time were more prone to corrosion. Traditionally, light lubricating oil was used to coat the cables, preventing rust from settling in. The cables were exposed to a steam heating tank, containing light oil at ninety-five degrees Fahrenheit. The problem was that the oil had a lower than average viscosity and tended to disappear after a period of time. Oil immersion heaters Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before. The trick was to heat it up to 220F, and make the oil more viscous without sacrificing the quality of the cables. Wattco provided 12 immersion heaters, each with 9KW 480V 3PH that had control panels and a redundancy system that prevented downtime. Thermocouples for heater safety Two thermocouples were used – one for temperature control and the other for high limit shutoff to safeguard the heaters. The heaters were also overrated to provide the customer additional power available. 120,000 LBS of cable was able to be treated with oil reaching 210 degrees temperature. Wattco suggested a high limit setting of 275 degrees to avoid overheating. This was easily programmed in the digital temperature controllers. Once we installed the new system, the process was monitored for 6 months and found no additional signs of corrosion. Benefits include: No maintenance costs on process heaters Safety temperature controller that prevents overheating Cables are fully protected from corrosion Electric industrial heaters are fairly inexpensive and last for years

Electricity produced through solar panels is used for heating water effectively and efficiently when attached to immersion water heaters equipped with sensors and controls. Depending on the average hours of daylight and the number of panels contained in the system, not all of the electricity produced is utilized in the home or business. Some of the electricity produced can be stored for later use. Or, sold back to the electric company for cash or credits. Unused electricity When businesses are “hooked to the grid” they can sell unused electricity to the power company, depending on state and local regulations. “Hooked to the grid” simply means the home or business's electric power remains tied into the municipal or private power company. So excess electricity can be sold. Or, if not enough electricity is generated by the solar power system the homeowner has immediate access to electricity. Using solar heaters Most electric companies pay far less than what they would sell everyone the same electricity for. So it’s better to store and use, than export to the grid. Circulation water heaters (or “inline water heaters”) particularly those used in a solar power system have far more uses than they are currently being used for in the home. Many homeowners would find it far too expensive to use these water heating elements for their pool Many homeowners would find it far too expensive to use these water heating elements for their pool while buying electricity from a power company. But when produced by the sun, it is more cost-effective. Certainly, pools and steam rooms are extravagant uses for solar-powered water heaters. For those already using these luxuries, heating the water more efficiently keeps more money in their wallets for other necessities. Heat radiation Many places are utilizing warm floors to heat their homes. Since heat rises, the floor is a good place to start with any heating system. Pipes laid in the floors, hooked to an electric water heater with concrete poured over them, make excellent radiant heating. Particularly when those floors are tiled. Solar Power System It is surprising how many large corporations continue to spend large amounts of money on electricity without considering solar power system solutions. A circulation system can be used to heat a building inexpensively using solar panels tied into the grid as insurance for electricity during extended periods of darkness. Keep in mind that even cloudy days produce some solar power. Using an immersion water heater to heat a plant or office building is cost-effective, even though the initial cash outlay may be expensive to build that solar power system. Cost-effective Tying solar power systems into the local electric system is not only wise. It can also be financially beneficial depending on the amount of electricity generated versus the amount of electricity used. Utilizing a backup plan is always the preferred method. Therefore, it is best to hook into a battery storage system for one’s solar power system. As stated previously, it’s more profitable to use one’s own electricity produced than to sell it to the power company, but the latter is a viable alternative when excess electricity is produced. Grid Connection is Essential Maintaining a connection to the grid makes sense in a variety of ways. It provides an outlet for the sale of the excess electricity produced and a reliable backup during extended periods of low production. There is always a possibility of overproducing and selling electricity back to the power company Sure, there is always a possibility of overproducing and selling electricity back to the power company. That’s more of a bonus; however, it is much more beneficial to be able to flip the switch and use your grid connection to warm your home or power your business. Actually, in most cases the change over from grid to solar or battery backup is seamless. Utilizing Storage Tanks Another backup source for heated water is storage tanks. Using an immersion heater for water tanks will ensure that after the water is heated, either by solar or the regular power source it can be stored in insulated storage tanks for later use. Temperature control panels can be placed within the tanks that control the water heater to ensure consistent heat. Many homes now use solar to circulate and heat their water by the sun’s warmth. These only use their immersion circulation heaters for backup. Valuable alternative These are particularly beneficial to municipalities that maintain purified water for residents’ use. Although hot water is not normally provided to the residents, freeze protection is provided through water temperature controls. These can also be linked to solar power systems with immersion water heaters that could be placed on, in, or around the storage tanks. In summary, immersion water heaters coupled with a solar power system are a valuable alternative to high-cost electricity and heat or hot water production in the home or business.

Florida-based tanker transportation and fleet management company, Oakley Transport is no stranger to success. Its roots date back to 1961, starting out as an independent citrus fruit broker, before entering into the harvest and hauling sector of the citrus industry. Specialized tanker transport In 1986, Oakley Transport diversified into the transport of liquid food grade products and quickly became one of the top transporters in specialized tanker transportation services. And just four years ago, the company expanded once again, however, this time into the reefer segment. “With a request from key partners, we entered the refrigerated side of business in late 2016 to move many of the finished goods that came from the tanker division. It was a natural way to further diversify and a great growth opportunity,” said Thomas E. Oakley of Oakley Transport. It allowed us an opportunity to introduce the Thermo King brand into our fleet" Tom adds, “It also allowed us an opportunity to introduce the Thermo King brand into our fleet, an opportunity that continues to expand.” ISO 9001 and ISO 22000 certification Those opportunities are no accident. According to Thomas E. Oakley, President and Chief Executive Officer (CEO), Oakley Transport, “The company has always aligned its vision with core values – and that has provided competitive advantages. Indeed Oakley Transport’s reputation for reliable service, dependable drivers, and industry leadership as early adopters of the FDA’s Food Safety Modernization Act and ELDs, has earned the organization certification in ISO 9001 and ISO 22000 standards, positioning them well throughout the industry.” TriPac Evolution auxiliary power units Reliability of equipment is paramount for Oakley Transport as it ensures timely deliveries, offers performance efficiencies and contributes to driver retention rates. Oakley was pleased with the quality its first Thermo King reefers provided so in 2019, decided to give the TriPac Evolution auxiliary power unit (APU) a try as well. The company conducted a pilot test of Thermo King’s TriPac Evolution APUs with the support of Thermo King of the Southeast (TKSE), the local Thermo King dealership. Reduced fuel consumption and emissions “We were looking to improve truck idle times and keep them in the single digits – nine percent or less,” said Pete Nativo, Vice President of fleet maintenance for Oakley Transport, adding “While APUs reduce fuel consumption, emissions and noise levels, they also keep the drivers comfortable – by providing heat and power for amenities that make road life a little more like home life.” Feedback from our drivers has been good – they like the TriPac’s easy-to-use controls" Pete Nativo adds, “Feedback from our drivers has been good – they like the TriPac’s easy-to-use controls. They also believe it starts easier. Most importantly, the TriPac has been very reliable. TKSE is a great local partner and if something does go wrong out on the road, Thermo King’s expansive dealer network allows for easy serviceability for our long-haul drivers.” He further states, “Bottom line is that Thermo King of the Southeast and Thermo King have proven to be trusting and reliable partners who offer consistent, quality service that aligns with our own standards.” Reliability of Tripac Evolution APUs The pilot of five TriPac Evolution auxiliary power units (APUs) in 2019 led to an order of approximately 200 more in 2020, demonstrating Oakley’s commitment to driver comfort and ultimately, retention. “We were really excited to work with Oakley Transport on the TriPac pilot as it allowed us the opportunity to demonstrate the performance and reliability of our APU with actual documentation on idling time, fuel consumption and more,” said Rob Race, Senior Account Executive at Thermo King of the Southeast (TKSE).
Boiler manufacturers Baxi Heating and Worcester Bosch have installed hydrogen burning boilers at ‘HyStreet’, in specially built demonstration houses at DNV GL’s specialist test site at Spadeadam in Northumberland, United Kingdom. The site has been used to complete over 200 tests, researching and proving the safety of converting homes and gas networks to hydrogen. The project is part of H21, a Network Innovation Competition project sponsored by Ofgem. Northern Gas Networks is leading the project with partners Cadent, Scottish Gas Networks, Wales & West Utilities, National Grid, DNV GL and the Health and Safety Executive’s science division. Combi boilers installed H21 is demonstrating how existing natural gas networks can be re-purposed to safely carry 100% hydrogen H21 is demonstrating how existing natural gas networks can be re-purposed to safely carry 100% hydrogen. For the first demonstration, both Worcester Bosch and Baxi Heating have installed combi boilers into the houses on HyStreet. The boilers have been developed as part of the UK Government-funded Hy4Heat program, which is also supporting the development of hydrogen-ready gas cookers, fires and gas meters. As around 85% of UK homes currently rely on natural gas for heating and hot water supply, re-purposing the natural gas grid for use with hydrogen would mean a low disruption option for householders to decarbonize their heating, without the need for extensive changes to their existing system. Tackling carbon emissions due to home heating Tackling carbon emissions resulting from home heating is utterly essential and one of the most difficult challenges in achieving net-zero emissions, given the need to make adaptations in almost every home. A growing library of studies and reports conclude that all viable scenarios for the UK to hit net-zero include hydrogen as a vital component. That is why Government and industry are working on various projects across the United Kingdom. Wide deployment of hydrogen boilers Tim Harwood, Northern Gas Networks’ Project Director for H21, said “Seeing the boilers in situ at Spadeadam is an exciting step in the journey to realizing our goal of a gas network transporting 100% hydrogen to customers. The hydrogen boiler looks and feels just like the natural gas version we all have today and is just as user-friendly, showing that a transition could cause minimal disruption to customers.” Dan Allason, Head of Research and Innovation, at DNV GL’s Spadeadam Research and Testing, said “Eight out of ten homes in the UK use a gas boiler to heat their homes and provide hot water and replacing all gas boilers with electric alternatives could be extremely costly. Both of the boiler manufacturers have developed options with their hydrogen ready prototypes to assist the switch to a lower carbon alternative.” Proof of concept and public acceptability We are delighted to be able to demonstrate this innovative new technology in a real-life setting in the UK" Dan adds, “Having these fitted to the HyStreet demonstration project at Spadeadam gives gravitas to the proof of concept and public acceptability of appliances such as these. The boilers are one of the first important steps.” Karen Boswell, Managing Director of Baxi Heating, said “This is an important step forward on our hydrogen journey and we are delighted to be able to demonstrate this innovative new technology in a real-life setting in the UK.” Zero-carbon alternative to natural gas Carl Arntzen, the Chief Executive Officer of Worcester Bosch commented “It is fantastic to see our prototype hydrogen boiler running successfully at this demonstration site. The boiler has operated seamlessly in its first month of operation and continues to provide both heating and hot water.” Carl adds, “It proves that hydrogen gas has great potential as a zero-carbon alternative to natural gas for heating and hot water in the UK and beyond. These initial tests are incredibly encouraging and will hopefully give key decision makers confidence to deploy hydrogen gas as a fuel for the future.”
