Why Refrigerant R22 must be replaced?At present, R22 is still the commonly used refrigerant in household air conditioners. As a HCFC refrigerant, R22 has a low ODP (ozone depletion potential) (only 5% of R12), but long-term use, the damage to the ozone layer is still not negligible.

At present, developed countries are phasing out second-generation (HCFCs, R22 as a representative) and third-generation (HFCs, R32 as a representative) fluorine-containing refrigerants, and overseas suppliers are gradually withdrawing from the market. However, the old refrigeration equipment has not
