Thermal Decomposition of Lower-GWP Refrigerants

The use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) has been widely restricted. They have been replaced with hydrofluorocarbons (HFCs) in order to protect the ozone layer. However, the leakage of refrigerant into air from active or end-of-life air conditioners has been a serious environmental issue owing to the high global warming potential (GWP) of HFCs. It has therefore...

New High Performance, Low GWP Refrigerants for Stationary AC and Refrigeration

In response to concerns about global climate change, and in consideration of probable legislation that may impact the production and use of refrigerants with high global warming potential, a set of new refrigerant candidates has been developed for evaluation. Some candidates are designed for stationary air conditioning in residential and light commercial end uses. Other refrigerant candidates w...

Performance of R410A and R22 Low GWP Alternative Refrigerants at Elevated Ambient Temperatures

Growing concerns about the global warming impact of refrigerants used in HVAC&R equipment are driving development and evaluation of alternative refrigerants with lower global warming potentials (GWPs). The Air Conditioning, Heating, and Refrigeration Institute (AHRI) recently coordinated the Low-GWP Alternative Refrigerant Evaluation Program (AREP) in which commercial, university, and governmen...

AHRI Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP) â•fi Summary of Phase I Testing Results

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently completed the first phase of its low global warming potential alternative refrigerants evaluation program (Low-GWP AREP). This industry-wide cooperative research program identified and evaluated promising alternative refrigerants’ performance over the past two years. Thirty-eight low-GWP refrigerants were tested during t...
