Basic performance of R32 refrigerant
The alternative to R22 is R32. The ozone depleting potential (ODP) of R32 refrigerant is 0, the global warming coefficient (GWP) is 0.11, and the working pressure is basically equivalent to that of R410A. With the same cooling capacity, the charging capacity of R32 is only about two-thirds of that of R22. Compared with R290, R32 has only low flammability. Compared with R410A, R32's global warming coefficient is only about one-third of the former. These advantages make it one of the most potential R22 substitutes. R32's energy-saving, green, and non-damaging ozone layer has also become one of the new refrigerants of modern refrigerants.
