Cold storage chlorodifluoromethane r-22 is a colorless, almost odorless gas at room temperature, non-flammable, non-explosive, non-corrosive, and its toxicity is slightly greater than R12, but it is still a safe refrigerant and is classified as A1; it can be liquefied under pressure. Colorless and transparent liquid. The chemical and thermal stability of chlorodifluoromethane r-22 is very high, especially in the absence of water, it does not react with general metals below 200°C. In the presence of water, it only works slowly with alkali. However, cracking occurs at high temperatures. Chlorodifluoromethane r-22 is a low-temperature refrigerant, which can obtain a cooling temperature of -80°C.

　　The main purpose

　　Cold storage chlorodifluoromethane r-22, as a widely used medium and low-temperature refrigerant today, is mainly used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freeze dryers, cold storage, food refrigeration equipment, and marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets, and other refrigeration equipment. Difluoromonochloromethane 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 foaming agent for polymers (plastics).

　　Used in reciprocating compressors, as a refrigerant in industrial, commercial, and household air conditioning systems; it can also be used as an aerosol spray agent for pesticides and spray paint, and it can also be used to produce fire extinguishing agent 1211; it is the production of various fluorine-containing polymers The basic raw material of the compound.
