What type of refrigerant is used in domestic air conditioners?

The refrigerant models often used in domestic air conditioners are R22 and R410a. \r\nR22 is used in fixed-frequency air conditioners, and is a transitional refrigerant because of its destructive effect on the ozone layer. \r\nR22 Characteristics: \r\nR22 at room temperature for colorless, nearly odorless gas, non-combustible, non-explosive, non-corrosive, slightly more toxic than R12, but still a safe refrigerant, safety classification for the A1; pressurized liquefaction of a colorless transparent liquid.R22's chemical stability and thermal stability are very high, especially in the absence of water in the presence of the case, at 200 ℃ below the general metal with the R22 does not react. In the presence of water, it only reacts slowly with alkali. However, it will be cracked at high temperatures.R22 is a low-temperature refrigerant that can obtain a cooling temperature of -80℃. \r\nR410a is used in inverter air conditioners. It is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. The working pressure is about 1.6 times that of an ordinary R22 air conditioner, which has a high cooling (heating) efficiency, improves the performance of the air conditioner and does not destroy the ozone layer. \r\nR410a Characteristics: \r\nR410a new refrigerant consists of two quasi***boiling mixture of R32 and R125 each 50%, mainly hydrogen, fluorine and carbon elements (expressed as hfc), with stable, non-toxic, superior performance and other characteristics. At the same time, because it does not contain chlorine, it will not react with ozone, that is, it will not destroy the ozone layer. In addition, the use of the new refrigerant air conditioning in the performance will also have a certain degree of improvement. R410A is so far internationally recognized as the most suitable refrigerant used to replace R22, and in Europe and the United States, Japan and other countries have been popularized. R410A replacement of the global trend in the major international markets and outlook for the use of the situation and the dynamics of the entry into the international market.
