Honeywell R22 refrigerant, also known as R-22, difluoro-chloromethane, Freon 22, F-22, refrigerant HCFC-22.
R22 refrigerant is used in reciprocating compressors and is used in household air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freezing dryers, cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, freezing condensation units, supermarket display cabinets and other refrigeration equipment;R22 is also widely used as a raw material for polytetrafluoroethylene resin and an intermediate for the gas fire extinguishing agent R1211, as well as a physical foaming agent for polymers (plastics). It can also be used as aerosol propellants for pesticides and spray paint. It is a basic raw material for the production of various fluorine-containing polymer compounds.
Honeywell R22 is the most widely used medium and low temperature refrigerant today. It is mainly used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freezing dryers, cold warehouses, food freezing equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, freezing condensation units, supermarket display cabinets and other refrigeration equipment. Difluorochloromethane can also be used as a raw material for the production of polytetrafluoroethylene resin and an intermediate for fire extinguishing agent 1121, as well as a physical blowing agent for polymers (plastics).
