Why is R-134a refrigerant called the most widely used environmental protection refrigerant

R-134a refrigerant, alias R134a, HFC134a, HFC-134a, tetrafluoroethane, Chinese name tetrafluoroethane, English name 1,1,1,2-tetrafluoroethane, chemical name 1,1,1,2 tetrafluoroethane Ethane, the molecular formula CH2FCF3. Because R-134a belongs to HFC substances (non-ODS substances Ozone-depleting Substances)-it does not destroy the ozone layer at all. It is an environmentally friendly refrigerant recognized and recommended by most countries in the world. It is also the mainstream environmentally friendly refrigerant. It is used for the initial installation of new refrigeration and air-conditioning equipment and the addition during the maintenance process.

The main purpose:

R-134a is the most widely used medium and low temperature environmentally friendly refrigerant. Due to the good comprehensive performance of HFC-134a, it becomes 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, automobile air conditioners, air conditioners, dehumidifiers, cold storage, commercial refrigeration, ice It can also be used in refrigeration equipment such as water machine, R134 refrigerant tube ice cream machine, freezing and condensing unit, and can also be used in aerosol propellant, medical aerosol, insecticide propellant, polymer (plastic) physical foaming agent, and magnesium alloy protective gas Wait.

Although R134a refrigerant is the most common choice for replacing Freon R12 on newly installed refrigeration equipment, the physical and chemical properties, theoretical cycle performance, and compressor oil of R134a and R12 are different, so the refrigeration equipment initially installed as R12 refrigerant After-sales maintenance, if you need to add or replace the refrigerant, you still can only add R12, usually R134a can not be directly replaced by R12 (that is, usually cannot be replaced by blood replacement).
