Common refrigerant for household air conditioning

Refrigerants commonly used in household air conditioners are R22 and R410a. R22 is used in fixed-frequency air conditioning, and is a transitional refrigerant because it has a certain destruction of the ozone layer.

R22 characteristics: at room temperature is colorless, approximately odorless gas, no combustion, no explosion, no corrosion, toxicity is slightly larger than R12, but it is still a safe refrigerant, safety classification is A1; Under pressure, it can be liquefied into a colorless transparent liquid. The chemical and thermal stability of R22 is very high, especially in the absence of water, and does not react with general metals below 200 ° C. In the presence of water, it acts only slowly with alkali. But it will crack at high temperatures. R22 is a low temperature refrigerant that can achieve a cooling temperature of -80 ° C. R410a is used in variable frequency air conditioners. It is a new type of environmentally friendly refrigerant, does not destroy the ozone layer, the working pressure is about 1.6 times of the ordinary R22 air conditioning, refrigeration (warming) efficiency is high, improve the performance of air conditioning, does not destroy the ozone layer.https://www.myrefrigerant.com/collections/r22

R410a Features: R410a is a new refrigerant composed of two quasi-azeotropic mixtures, R32 and R125, each accounting for 50%. It is mainly composed of hydrogen, fluorine, and carbon (expressed as HFC). It possesses stable, non-toxic, and superior performance characteristics. Moreover, since it does not contain chlorine, it does not react with ozone, thus not depleting the ozone layer. Additionally, air conditioning systems using this new refrigerant also experience performance improvements. R410A is currently the most suitable internationally recognized refrigerant to replace R22 and has been widely adopted in Europe, the United States, Japan, and other countries. The global trends and outlook for R410A replacement in major international markets, as well as usage and entry into international markets, are also included.https://www.heartfev.com/category/2002.html
