US EPA proposes acceptance of hydrocarbons and R32 in 6 applications
The US EPA has proposed a range of acceptable uses for hydrocarbon refrigerants – R600a, R290, R170 and R441A along with R32 under the EPA’s Significant New Alternatives Policy (SNAP)
US: EPA expands the use of 4 hydrocarbons and R32
The US Environmental Protection Agency (EPA) recently authorised the use of four hydrocarbon refrigerants and R32 in various applications.
Reducing the environmental impact of ultra-low temperature refrigeration systems
Ultra-low temperature (ULT) refrigeration systems often use very high-GWP HFCs. Yet, ULT systems are excluded from the scope of the regulations aimed at phasing-down HFCs. An IJR paper reviews the most promising...

Hydrocarbon refrigerants
Hydrocarbons such as R290 (propane), R600a (isobutane) or R1270 (propene/propylene) are low GWP non-toxic natural refrigerants with excellent thermodynamic properties. They offer an...
Global warming potential (GWP) of HFC refrigerants
Using the latest updated data from UNEP’s RTOC 2022 report, we have compiled the 100-year GWP and 20-year GWP values of hydrofluorocarbon-based (HFC) refrigerants. Our table includes...
