1) Production of R11 or CFC-11 was halted by the clean air act on January 1, 1996
2) Production of R12 or CFC-12 (Dichlorodifluoromethane) was halted by the clean air act on January 1, 1996
3) R22 or HCFC-22 is a single component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air-conditioning and refrigeration applications in a variety of markets, including appliance, construction, food processing, and supermarkets. Production of R-22 halted in US 2015.
4) Production of R113 or CFC-113 was halted by the clean air act on January 1, 1996
5) R123 or HCFC-123 is a replacement for R11 in chillers and is providing this new refrigerant to chiller manufacturers for use in new and existing chillers
6) Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems
7) Production of R-500 was halted by the clean air act on January 1, 1996.
