What are the main types of air conditioning refrigerants?

Air conditioning refrigerant is also called snow seed. It is usually said that air conditioning is not cold enough and needs snow seed, that is, refrigerant. Refrigerant is an essential thing in air conditioning and refrigeration system, and its importance is equivalent to blood in human body. Without blood in the refrigeration system, the air conditioning and refrigeration system can't work. At present, R22, R4 10A and R32 are commonly used refrigerants in air conditioning.

Introduction of R4 10A air conditioning refrigerant;

R4 10A, as a widely used medium-high temperature refrigerant, is mainly used in household air conditioners, small and medium-sized commercial air conditioners (small and medium-sized unit air conditioners, household central air conditioners, multi-unit 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 JH? R-4 10A refrigerant. Juhua R-4 10A belongs to HFC-type near-boiling-point environment-friendly refrigerant (completely free of CFCs and HCFCs that destroy the ozone layer), which is widely used for initial installation and re-addition in the maintenance of new refrigeration equipment.

Introduction of R22 air conditioning refrigerant;

R22 refrigerant is mainly used in household air conditioners, commercial refrigeration, central air conditioners, large centrifugal compressor 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 substances (the second batch of ODS substances with restricted use, the second category of ozone-depleting substances), which is harmful to the ozone layer and has a greenhouse effect. Therefore, developed countries (EU, Japan and the United States) 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.

Introduction of 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.

At present, Gree air conditioners use R32 refrigerant.

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. ......
