R 134a does not contain the chlorine atom, will not destroy ozone layer; with good security performance (inflammable, non-explosive, non-toxic, does not have stimulation and corrosion); R 134a heat-transfer property is similar with R12, therefore the refrigeration system modification is quite easy. The gas is Colorless under normal temperature, and colorless tran***rent liquid under own pressure. It is the Widely applied in refrigerator, freezer and the automobile air-conditioning, also may be served as Aerosol in the medicine and cosmetic field.
The thermal and the physical property of HFC-134a, as well as its low toxicity, making it become one of the extremely effective and the safe substitute for R12 in refrigerant industry. HFC-134a is mainly applied in the automobile air conditioning, the domestic electric appliances, small fixed refrigeration, the center refrigerator in the supermarket and commercial refrigerator.
The compressor producer usually suggested POE (Polyol Ester) and PAG (Polyalkylene Glycol) as the freezer lubricating oil.
