Which type of refrigerant is generally used for household air conditioners

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 which is 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 all of air-conditioning refrigerants. However, 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 and R410A comparison

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 is 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. But 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: R410a new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 each 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, since 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 used to replace R22 in the international recognition so far, and it has been popularized in Europe, America, Japan and other countries. R410A replacement in the main international market global trends and prospects of usage and dynamics of entering the international market.

　　 The above is the related introduction of which model of household air conditioner is generally used. Note that the air conditioner refrigerant must be filled according to the model marked on the air conditioner to avoid damage to the air conditioner system.
