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).
Its use is banned in the UK and EU but several alternatives exist depending on the application.
