Non-ozone-depleting HFCs and HFC blends (e.g., R-410A and R-134a) have replaced HCFC and CFC refrigerants and now dominate the industry in developed countries. However, the GWPs of

4. HVAC AND REFRIGERATION SYSTEM
beeindia.gov.inUntil now, only one HFC based refrigerant, HFC 134a, has been developed. HCFCs are comparatively simpler to produce and the three refrigerants 22, 123, and 124 have been devel-oped. The use of HFCs and HCFCs results in slightly lower efficiencies as compared to CFCs, but this may change with increasing efforts being made to replace CFCs.

R32 Common Questions - AIRAH
www.airah.org.aurefrigerants. There is a diversity of low GWP refrigerants available to select from. These include HFC 32 (or R32), HFO 1234yf and HFO blends, Ammonia (R717), Propane (R290) and C02 (R744). Unfortunately, none of these candidates is a perfect refrigerant when assessed across the 4 key criteria of Environment, Energy Efficiency, Safety and Economy.
