Comparison of R22 and R134a refrigerants **1. Chemical Composition**R22 (Chlorodifluoromethane, HCFC-22) - Belongs to the HCFC (Hydrochlorofluorocarbon) family. - Contains chlorine, which contributes to ozone layer depletion. R134a (Tetrafluoroethane, HFC-134a): - Part of the HFC (Hydrofluoroc

In fact, R134a itself is a kind of HFC refrigerant that replaces R12, and it is generally recommended to use 404a, 407C, and 410a to replace it directly in fixed equipment. If you want to replace R134A refrigerant, you still need to replace the refrigeration oil with 12 refrigerant oil before you...

For the r22 refrigerant, the following methods can be used to determine the refrigerant:Method 1: Turn the refrigerant tank upside down and release a small amount of refrigerant onto a piece of white paper. If there are obvious impurities or liquid water on the white paper, the refrigerant is ...

Comparison of Refrigerant Gas R32, R410a and R290

The rising trend of third-generation refrigerants is expected to significantly surpass that of second-generation refrigerants. The reasons are: 1) The quota lock-in period for second-generation refrigerants is from 2009 to 2010. At that time, it coincided with the domestic home appliances going to...
