Cooling Chips, Cooling Paper And Other Research In Temperature Regulation

A focus of research and development in the HVAC arena has been to develop alternative materials and technologies that requires less energy to function while still providing a benefit to regulate temperature. More passive approaches to regulating temperature offer green benefits and yield new components in systems to regulate temperatures in the future. Here are some examples and a glimpse of what’s to come. Phase-change materials have drawn interest because of their ability to change the...

HVAC Industry Working To Make Net-Zero Emissions A Reality By 2050

‘Net zero’ is an unavoidable reality in the continuing fight against climate change. For example, both the United Kingdom and the European Union have set targets of having net-zero greenhouse gas emissions by 2050. These objectives are in line with a commitment to global climate action under the Paris Agreement. Net zero - carbon neutral Net zero refers to the balance between the amount of greenhouse gas produced and the amount removed from the atmosphere. It’s another term f...

Indoor Air Quality Is A Top-Three Concern For College Applicants And Parents

High school seniors and their parents weigh multiple factors, when choosing a college or university. In the aftermath of the COVID-19 pandemic, the importance of one factor has shown a marked increase. Indoor air quality (IAQ) is now among the top-three aspects that an applicant and their parents would consider, when choosing a college, according to one survey. Growing awareness of IAQ Growing awareness of IAQ presents an opportunity, as the HVAC industry seeks to serve the higher education ma...

Adaptive Intelligence Optimizes Energy And Green Impact Of Older Buildings

Many new buildings are constructed to maximize the efficiency of HVAC systems and to minimize their environmental impact. But what about older buildings? How can they work to achieve efficiency and environmental goals? One answer involves the use of artificial intelligence (AI).  “There are a lot of older buildings, and existing buildings are rarely demolished,” says Jean-Simon Venne, Co-Founder and Chief Technology Officer of Brainbox AI. “There are so many of them and t...

Students Get Hands-On HVAC/R Training Using Virtual Reality

When COVID-19 hit, North Arkansas College had to close its school, and students had to transition from in-person to online learning, which is especially difficult when teaching a trade that is heavily dependent on hands-on training. The HVAC/R program at North Arkansas College, which has existed for over 50 years, typically has an average of 14 to 16 students enrolled each year. HVAC/R program “With the quick transition we had to think outside the box, and so we found a company that had...

Johnson Controls Depending On R-454B To Achieve Regulatory Goals

The current Biden Administration’s renewed focus on climate change has expedited the phasedown of high-GWP refrigerants, kicked off by the passage of the American Innovation and Manufacturing (AIM) Act, part of the December 2020 COVID stimulus bill. As the AIM Act phase-down schedule progresses, higher-GWP HFC refrigerants, while viable, have the potential to have a limited useful life and ultimately be eliminated. In response to pending changes, Johnson Controls has announced it will use...

Using Near Field Communication (NFC) To Control HVAC Systems

Interfacing with HVAC products is increasingly complex. The tiny 1-inch LCD display included on systems does not lend itself to complicated functions. Keeping the HVAC user interface simple limits control options to on/off, mode change or choosing a temperature. Thermostat controls company COTHERM has developed a smartphone app that can be used to control complex functions such as product settings during installation, programming or providing technical information about an HVAC product. Near f...

WELL Building Standard Promotes ‘People-First’ Approach, Including HVAC

The COVID-19 pandemic has changed the way the world lives, escalating the need to prioritize health and safety where we live, work, learn and play. As organizations around the world respond to the pandemic, the International WELL Building Institute (IWBI) has leveraged its expertise to help. Impact of building surroundings IWBI is a public benefit corporation focused on deploying “people-first places” to advance a global culture of health. The community has adopted the WELL Buildin...

Supply Shortages, High Prices Plague Summer Outlook For HVAC Contractors

It’s shaping up to be a long, hot summer for HVAC contractors and their customers. Disruptions in the nationwide supply chain that began during the COVID-19 pandemic still have not been resolved. Shutdowns last summer played havoc with the supply of parts, and suppliers are still playing catch up, as raw materials remain scarce. Furthermore, prices are going up among some components and key raw materials. Waiting times for parts can run into weeks or even months. Supply shortages of HVAC...
