What Is Common Refrigerant for Household Air Conditioning ?
2024-05-23
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.
R410a Features: R410a new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 each 50%, mainly composed of hydrogen, fluorine and carbon (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 air conditioning using the new refrigerant will also have a certain improvement in performance. R410A is so far the most suitable refrigerant internationally recognized to replace R22, and has been popularized in Europe, the United States, Japan and other countries. Global trends and outlook of R410A replacement in major international markets and trends of usage and entry into international markets.
