Refrigerant 134a: This refrigerant is Hydrofluoro carbon(HFC) and have no effect ozone. Since more heat is absorbed when one pound vaporizes the liquid refrigerant entering the evaporator should be decreased by increasing the length of capillary. Bauxite drier should not be used since the oil reacts with this material. So molecular seive drier can be used.
