134A is a new type of freon refrigerant _ Natural Science _ professional information. Freon 134A is a new type of refrigerant, which belongs to the hydrofluoric hydrocarbon (HFC). The boiling point is -26.5 C. Its thermal performance is close to R12 (CFC12). The potential value of ozone destruction is ODP, which is 0, but the potential value of greenhouse effect WGP is 1300. It will not destroy the ozone layer in air. It is the environmental protection refrigerant advocated in recent years, but it will cause the greenhouse effect. It is now used in refrigerators, freezers, and automotive air conditioning systems to replace fluidine R12.
