Kinds of refrigerants

The refrigerant is widely used in the compression of the refrigerant is ammonia, freon and hydrocarbon.

According to the chemical composition, refrigerants can be divided into five types: inorganic compound refrigerants, freon, saturated hydrocarbon refrigerants, unsaturated hydrocarbons refrigerants and azeotropic refrigerants.

According to condensation pressure, refrigerants can be divided into three types: high temperature (low pressure) refrigerant, medium temperature (medium pressure) refrigerant and low temperature (high pressure) refrigerant.

Freon refrigerant commonly used by R12, R22, R502 and R1341a, because other types of refrigerant has now stopped or disabled.

Freon 12 (CF2CL2, R12): it is widely used in Freon refrigerants. It is widely used in refrigerating devices such as medium and small food banks, household refrigerators, and refrigerated transportation of water and road.

Freon 22 (CHF2CL, R22): one of the more widely used Freon refrigerants, mainly used in household air conditioners and low temperature refrigerators.

Freon 502 (R502): R502 is azeotropic solution composed of R12, R22 in 51.2% and 48.8% the percentage of mixing into.

Freon 134a (C2H2F4, R134a) is a new refrigerant, the evaporation temperature of -26.5.
