Description

R-22 has been the dominant refrigerant in residential and commercial air conditioning and some very large centrifugal chillers for air conditioning and industrial process cooling. It has also been used in refrigeration since the phase-out of CFCs, both as a pure refrigerant and in blends. R-22 is subject to reduced production and restriction in new equipment since 2010, and production ends in 2020. The use of R-22 is allowed until the R-22 supply has been depleted.

R22 is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself,non-toxic & inflammable with the excellent thermo-stability and chemicalstability, unable to erode metals and it is a refrigerant for low temperature to ﹣80℃ below. Used in reciprocating compressor, as refrigerant in industrial, commercial and household air-condition system; Also used to produce insecticide and aerosol for spraying paint; To produce extinguishing agent1211; As the basic material to produce a wide variety of fluorinated macromolecular compounds.
