What is the refrigerant of the air conditioner?

R22 air conditioning refrigerant: R22 refrigerant is mainly used for household air conditioning, commercial refrigeration, large centrifugal compressor water chillers, etc. R22 refrigerant, alias R22 refrigerant, Freon 22, F-22, HCFC-22, difluoromethane, trade name JH? R-22 refrigerant, Chinese name difluoromethane, English name Chlorodifuoromethane, chemical formula CHClF2.

R-22 belongs to HCFC substance (ODS substance II which is restricted in the first batch), which is harmful to the ozone layer and has a greenhouse effect. Developed countries (EU, Japan, USA) have stopped initially installing R-22 on new air-conditioning and refrigeration equipment. At present, there are basically no restrictions on the production, initial installation and re-addition of R22 refrigerant in China.

R32 air conditioning refrigerant: The chemical name of R32 refrigerant is difluoromethane, and the molecular formula is CH2F2. Difluoromethane is a coolant with zero ozone depletion potential. It is a gas at room temperature and a colorless and transparent liquid under its own pressure. Soluble in oil, insoluble in water.

R4 10A air conditioner refrigerant: As a widely used medium-high temperature refrigerant, R4 10A is mainly used in household air conditioners, small and medium-sized commercial air conditioners (small and medium-sized unit air conditioners, household air conditioners and multi-connected air conditioners), mobile air conditioners, dehumidifiers, freeze dryers, marine refrigeration equipment, industrial refrigeration and other refrigeration equipment.

R4 10A refrigerant, alias R4 10A refrigerant, product name JHR-4 10A refrigerant. R-4 10A belongs to HFC-type near-boiling environmental protection refrigerant (completely free of CFCs and HCFCs that destroy the ozone layer), which is widely used for the first installation and maintenance of new refrigeration equipment.

Warm reminder CRR: Now there are many means of fraud, and it is hard to prevent. In order to avoid the potential inferior refrigerant contacting the compressor and damaging it, you must buy a famous brand. ......
