R422A refrigerant for old R22 plants

R422A refrigerant is an HFC mixture that serves as a substitute for R22, R502 and HCFC-containing refrigerant mixtures (R402A, R402B, R409A) in low temperature commercial and industrial refrigeration systems with direct evaporation. It is also used in medium temperature systems.

According to the F-gas Regulation, the high GWP value 3134 (> 2500) means that R422A can no longer be used after the year 2020.

R422A refrigerant applications and use

R422A has still served as a replacement in older R22 plants – primarily refrigeration and freezer systems in commercial outlets. R422A and f.ex. R290 can be used to convert R502 systems without the need to change out the mineral oil (The Linde Group, 2016).

Research Gate study although portray refrigerant R290 as a better substitute for R502 than R422A – both from energy as well as environmental (by considering TEWI* index) point of view. But given the flammability issue of R290, R422A seems to be a short term alternative to replace R502 systems. From an other point of view the compressor discharge temperature of the refrigerated container system working with R422A is the lowest as compared to R290 as well as R502, which may increase the compressor life. It is observed that R422A has vapor pressure nearer to R502 as compared to R290. For R422A, the compressors will operate at slightly higher pressures.” *) TEWI = Total equivalent warming impact

Replacements

Replacement or alternative refrigerants are R422D,  R427A, R428A, R438A.
