At present, due to global warming, people use air conditioners more and more frequently, but not all users are familiar with the types and use of air conditioner refrigerants. Let us take a look at the best air conditioner refrigerant to buy. What is the type of refrigerant commonly used in household air conditioners?
Of course, R22 and R410A refrigerants are well known to everyone about air-conditioning refrigerants, but because r22 has a certain destructive effect on the ozone layer, it is a transitional refrigerant. The later derived R410A refrigerant is also widely used. The type of refrigerant used.
R22 characteristics: It is a colorless, almost odorless gas at room temperature, non-combustible, non-explosive, non-corrosive, slightly more toxic than R12, but still a safe refrigerant, safety classification A1; pressurized can be liquefied into colorless Transparent liquid. R22 has high chemical and thermal stability, especially in the absence of water, it does not react with general metals below 200°C. In the presence of water, it only works slowly with alkali. However, cracking occurs at high temperatures. R22 is a low-temperature refrigerant, which can obtain a cooling temperature of -80°C.
R410a is used in inverter air conditioners. It is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. Its working pressure is about 1.6 times that of ordinary R22 air conditioners. It has high cooling (heating) efficiency and improves air conditioning performance without destroying the ozone layer.
R410a characteristics: The new R410a refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 each with 50%, mainly composed of hydrogen, fluorine and carbon elements (expressed as hfc), which is stable, non-toxic, and superior in performance. 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 performance of air conditioners using new refrigerants will also be improved. R410A is the most suitable refrigerant to replace R22, which is recognized internationally so far, and it has been popularized in Europe, America, Japan and other countries. R410A replaces the global trends in major international markets and prospects for its use and the dynamics of entering the international market.
