sulfuryl fluoride fumigant, also known as refrigerant, usually everyone hears that the air conditioner is not cold enough to add refrigerant, and the refrigerant is added. Refrigerant is an indispensable thing in the air-conditioning refrigeration system. Its importance is equivalent to the blood in the human body. Without blood in the refrigeration system, the air-conditioning refrigeration system cannot work. At present, the commonly used air-conditioning refrigerants are R22, R410A, and R32.

R410A refrigerant
As a medium and high temperature refrigerant widely used today, R410A is mainly used in household air conditioners, small and medium commercial air conditioners (small and medium unit air conditioners, residential central air conditioners, multi-line), mobile air conditioners, dehumidifiers, refrigerated dryers, and marine refrigeration Equipment, industrial refrigeration and other refrigeration equipment.

R410A refrigerant, alias R410A refrigerant, trade name JH®R-410A refrigerant. Since Juhua R-410A belongs to the HFC-type near-azeotropic environmentally friendly refrigerant (completely free of ozone-depleting CFC and HCFC), it is widely used in the initial installation of new refrigeration equipment and re-addition in the maintenance process.

Introduction of R22 Air Conditioning Refrigerant

R22 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, difluoromonochloromethane, product name JH®R-22 refrigerant, Chinese name difluoromonochloromethane, English name Chlorodifuoromethane, chemical formula CHClF2. Since R-22 belongs to the HCFC class of substances (the second batch of restricted ODS substances, Class II Ozone-depleting Substances), which destroys the ozone layer and has a greenhouse effect, it has been discontinued in developed countries (EU, Japan, and the United States) In addition to the initial installation of new air-conditioning and refrigeration equipment; China currently has basically no restrictions on the production, initial installation, and addition of R22 refrigerant.

Introduction to Heptafluoropropane HFC-227EA

R32 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. It is easily soluble in oil but hardly soluble in water.

Gree air-conditioning currently uses R32 refrigerant.
