What type of refrigerant home air conditioning?
Household air conditioner commonly used models with R22 and R410a refrigerant. R22 used in air conditioning that decide frequency, due to the destruction of the ozone layer has a certain effect, therefore is a kind of transitional refrigerants. R22 features: At room temperature for colorless, approximate tasteless gas, not burning, explosion, corrosion, toxicity than R12 slightly larger, but is still a safe refrigerants, security classification for A1; Pressure can be liquefied colorless transparent liquid. Chemical stability and thermal stability of R22 are very high, especially in without the presence of moisture, can't afford to under 200 ℃ and general metal reaction. In water, only with alkali slow work. It happens in high temperature cracking. Available as refrigerant R22 is a kind of low temperature, refrigeration temperature to 80 ℃. R410a used in frequency conversion air conditioning. It is a new kind of environmental protection refrigerants, does not destroy the ozone layer, the working pressure is about 1.6 times that of ordinary R22 air conditioner, refrigeration (warm) of high efficiency and improve the performance of air conditioning does not destroy the ozone layer. R410a features: New refrigerant R410a is composed of two kinds of quasi azeotropic mixture of R32 and R125 each 50%, mainly include hydrogen, fluorine and carbon (HFC), has the stability, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, which does not destroy the ozone layer. In addition, the adoption of new refrigerant of the air conditioning in terms of performance also improved. R410A is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. R410A replacement in the main international market of global trends and prospects of using condition and the dynamic of entering the international market.
What air conditioning compressor is suited to the refrigerant, if the mark is to use with R22 refrigerant R22, if that want to use it with R410A refrigerant R410A refrigerant. Now has a good air conditioning refrigerant R410A refrigerant dupont, JuHua R410A refrigerant R410A refrigerant, daikin and so on
General fixed frequency machine is to use traditional R22, frequency changer now multi-purpose R410A
