Introduction of 3 types of flammable refrigerant gas, namely R32, R290 and R600a.

Comparison of R32 and R410ASaturation pressure: R32 and R410A have similar pressures. So it is easier to develop R32 system based on R410A platform.Critical temperature: R32 has a higher critical temperature, so the COP is higher.Latent heat of evaporation: The heat required to evaporate R32 is high

The harm of chlorofluorocarbon refrigerants to the ozone layerChlorofluorocarbon is a kind of flammable organic substance which is easy to gasify and volatile.The most common is R22 (HCFC22 is Hydrochlorofluorocarbon 22), which was commonly used in refrigerators in the last century.It is R12 (CFC12)

This passage mainly introduces the different performance of air conditioning refrigerant gas R22,R410a,R32 and new type refrigerant gas R290.

Following we list the refrigerant safety classification of the common use refrigerant gas types.
