The new refrigerant means R410A refrigerant. Compared with the previous refrigerant R22, it does not destroy the ozone layer. The working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (warming) efficiency is high.

The new refrigerant is composed of two quasi-boiling mixtures, R32 and R125, 50% each. It is mainly composed of hydrogen, fluorine and carbon elements (expressed as hfc). It is stable, non-toxic, and has superior performance. Features.

Extended information

R22 refrigerant compressor generally uses mineral oil; R410A refrigerant compressor generally uses organic synthetic oil, common POE (ether), PVE (ester). R410A and mineral oil are not miscible with each other. Mixing mineral oil (for R22) into the R410A air-conditioning system will cause the refrigeration oil to deteriorate and hydrolyze to form metal salts.

The pressure of R410A is about 1.6 times higher than that of R22 refrigerant (absolute pressure = relative pressure or gauge pressure 1 atmosphere or 1 kilogram force). Therefore, if an error occurs during construction and after-sales service, operation, major accidents may occur.

R410A is used for initial installation on new refrigeration equipment and re-adding during maintenance. Complies with the standards of the US environmental organizations EPA, SNAP and UL, and complies with the A1 safety level category of the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE)
