Refrigerant Gas R-134a is the most widely used medium and low temperature environmentally friendly refrigerant. Due to the good comprehensive performance of HFC-134a, it is a very effective and safe alternative to CFC-12. It is mainly used in the use of R-12 (R12). , Freon 12, F-12, CFC-12, Freon 12, dichlorodifluoromethane) refrigerants in most areas, including: refrigerators, freezers, water dispensers, automotive air conditioning, central air conditioning, dehumidifiers, cold storage, commercial refrigeration, In the refrigeration equipment such as ice water machine, ice cream machine and freezing condensing unit, it can also be applied to aerosol propellant, medical aerosol, insecticide propellant, polymer (plastic) physical foaming agent, and magnesium alloy protection. Gas, etc.
Although R134a refrigerant is the most popular alternative to Freon R12 in new refrigeration equipment, but because air conditioning refrigerant R134a and R12 have different physical and chemical properties, theoretical cycle performance and compressor oil, it is suitable for refrigeration equipment that is initially installed as R12 refrigerant. After-sales maintenance, if you need to add or replace the refrigerant, you can only add R12, usually can not directly replace R12 with R134a (that is, usually can not be replaced by blood exchange)
