R-22 is a "hydrochlorofluorocarbon" refrigerant with high latent heat of vaporisation used for domestic, commercial and industrial air conditioning.
Used at low temperatures (up to -40°C), R-22 is also suited for refrigeration and deep freezing. In energy saving applications, it allows the production of heat pumps with average temperature heat sources (55°C maximum).

FreonTM MO79 is a zeotropic HFC blend designed as a direct replacement for R-22 based blends (which previously replaced R-502), such as R402A, R403B and R408A. It tends to be used in lower temperature refrigeration systems. .
R-422D (FreonTM MO29) is a zeotropic HFC blend designed as a direct replacement R-22 in direct expansion (Dx) refrigeration and air conditioning systems. It can also be used in water chillers but care is sometimes needed with the expansion device.
R-427A is a zeotropic HFC blend which has been designed to replace R-22 (HCFC) by conversion of existing systems or for use in new systems. It may be used in direct expansion refrigeration systems and air conditioning.
