The assemblies and pipe work system of the air conditioner are filled with refrigerant R134a (tetrafluorethane, CF3-CH2F or CH2F-CF3).
At present the R134a refrigerant pressure vessels are labelled with the following trade names:
-
‒ H-FKW 134a
-
‒ SUVA 134a
-
‒ ARCTON 134a
These trade names may vary from country to country.
Further information:
