HVAC Software - Editor's Note
Excessive heat is a byproduct of data center servers and one that presents both economic and environmental challenges. Data centers are one of the world's fastest-growing contributors of CO2 emissions, for example, currently generating well over 100 million tonnes of CO2 globally per annum. This roughly equates to half of the global aviation emissions, 30 million cars or 36 coal-fired power plants. Currently, data centers waste over 200TWhrs of energy annually, on a global scale. Sustaina...
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 conditi...
This year’s Texas deep freeze struck the region hard, causing an estimated $10 billion in damage. It was one of the costliest winter weather events in the state’s history. The extreme weather conditions severely impacted HVAC systems, too, overtaxing equipment and challenging contractors to keep up with the pace of repairs. What did not happen, despite some homeowner insurance claims filed in the aftermath of the extreme cold snap, was ‘frozen refrigerant.’ Although the...
The most likely scenario for the next 12 months in the United Kingdom is far lower risk of serious COVID-19 illness due to the vaccine. However, there will be big swings in R rates, and there is uncertainty about how effective vaccines will be against COVID variants. The ‘R’ rate is the number of people one infected person will pass a virus on to, on average. As the scenario plays out, and more companies open for business, issues of indoor air quality will continue to be top of mind...
Innovation is a driving force behind most industries, including HVAC. Keeping up with industry research, and looking toward the future, helps HVAC professionals to anticipate upcoming changes to the industry, and to be prepared when they happen. There is no shortage of innovation in the sphere of HVAC. I recently came across some interesting designs (and one product already on the market!) that provide a useful glimpse into the types of projects that may shape the HVAC industry of tomorrow. La...
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 protoc...
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...
The demographics of the HVAC workforce are changing and more women are being welcomed into the HVAC industry in a wider variety of roles. In part, the changes are because of necessity as Baby Boomers retire from the workforce and leave a labor and skills gap to be filled. HVAC commercial service business, HB McClure Company, based out of Harrisburg, Pennsylvania, is embracing change and encouraging more women to consider a career in the HVAC workspace. The company’s female employees are h...
The computing power we know as the Internet actually resides in millions of data centers that house rows and rows of computer servers. And each data center represents a unique HVAC challenge: How to keep the equipment cool, the air pure and the humidity low. Providing the ideal operating conditions for a room full of computers requires the best that the HVAC market can offer. Data centers come in all shapes, sizes and configurations. Some are huge facilities that serve the needs of giants...
During the coronavirus pandemic, UV-C systems have surged from a niche market to mass production capable of meeting historic demand levels. As a result, UV lamp manufacturers, as well as their component providers (e.g., glass suppliers), have struggled to meet the growing demand. Because of UV-C’s historic proven effectiveness, interest in and orders for UV disinfection equipment have increased exponentially during the COVID-19 pandemic. For example, in July, lighting manufacturer Signify...
The amount of carbon dioxide (CO2) in a poorly ventilated indoor space depends on the number of people who exhale their breath in that space. And aerosol virus contained in exhaled breath is a common way that COVID-19 germs are spread. Therefore, might the CO2 level in a given space serve as an approximation of the likelihood of coronavirus spread? Broadly speaking, poor ventilation of indoor spaces can increase the likelihood of aerosol transmission, and a higher CO2 level is an indicator of i...

Elon Musk has proclaimed that HVAC is his ‘pet project’ and has even suggested a timeline: ‘Maybe we can start working on that.’ As a high-profile business magnate, industrial designer and engineer, Musk is CEO of automobile company Tesla, whose goal is to accelerate the use of sustainable energy. Tesla is on the cutting edge of technologies that can transform how we use energy, and Musk believes the benefit of that technology will translate well into home HVAC systems....
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 thos...
A 93-year old woman in Glasgow, Ky., lost her husband last November after 73 years of marriage. Thousands of miles away, a disabled veteran in Rancho Cordova, Calif., suffers from asthma. Both were in dire need of a new HVAC unit, and neither could afford it. They are two of the 210 recipients of new HVAC units in the Lennox International “Feel the Love” campaign for 2020, which honors residents and families facing physical, mental or social disabilities, financial challenges, or th...
The cannabis industry offers unique challenges to the HVAC market, including the need to create an optimum indoor grow room environment that perfectly balances variables such as temperature, humidity and airflow at each stage of a plant’s growth cycle. The consequence of a system failure could be the catastrophic financial loss of an entire crop. Despite these weighty challenges, there is opportunity aplenty for HVAC installers in the emerging cannabis industry. Legalized cannabis is expa...
Closed and cramped environments are especially problematic to the spread of the novel coronavirus that causes COVID-19. A ‘smart’ glass-paneled bus stop shelter, developed in Korea, embodies new approaches to making such spaces safe, including elements of HVAC. Smart shelters The smart shelters are closed-in glass cubes that serve as bus stops in the Seongdong district in northeastern Seoul, South Korea. The local district office collaborated with LG Electronics to develop the futu...
