NevadaNano, the globally renowned innovator in gas detection sensor technology, has announced its partnership with Emerson, to jointly develop refrigerant gas detector products, which will provide a solution to the heating, ventilation, air conditioning and refrigeration (HVACR) industry, for refrigerant leak detection. NevadaNano - Emerson partnership “We are proud to partner with Emerson to develop essential solutions that can help lower the impact of existing HVACR equipment on the gl...

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...

Johnson Controls Selects R-454B GWP Refrigerant In Their Ducted HVAC Equipment And Air-Cooled Scroll Chillers

After extensive research, testing, and evaluation, Johnson Controls, the provider of smart, healthy, and sustainable buildings, has selected R-454B, a lower global warming potential (GWP) refrigerant, to replace R-410A in its ducted residential and commercial unitary products as well as air-cooled scroll chillers. Systems using the new refrigerant will be available for Johnson Controls, YORK®, Luxaire®, Coleman®, Champion®, TempMaster®, Fraser-Johnston®, Guardian®, E...

Why The 2030 Deadline For Zero GWP Isn't Achievable

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 C...

Making The Right Refrigerant Choice

When choosing a chiller, there’s more to reducing emissions than the choice of refrigerant. Following is what one needs to know about chillers and new, low-GWP (Global Warming Potential) refrigerant alternatives. 3 Things To Know About Safety Some refrigerant alternatives are mildly flammable: All high-pressure refrigerant alternatives have some degree of flammability. To use these alternatives safely, there are significant implications on product configuration, installation cost, and...

Understanding The Impact Of The Texas Freeze On HVAC Systems

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...
