Refrigerant compressor

Abstract

Abstract PURPOSE:To improve durability by using a mixture with at least one kind selected among a group of polyether oil, naphthene oil, paraffin oil and alkyl benzene synthetic oil for a refrigerator oil in a refrigerant compressor using tetrafluoroethane as a refrigerant. CONSTITUTION:A refrigerator oil 9 is sucked as a rotary shaft 5 is rotated, and it is circulated in sliding portions in a compressing mechanism 6 and a motor mechanism 4. A mixture of polyether oil, naphthene oil, paraffin oil and alkyl benzene synthetic oil is used for this refrigerator oil 9. Polyether oil such as polyalkylene glycol ether has good solubility in tetrafluoroethane, the solution for a refrigerant is secured by this polyether oil, the circulation property is held, and the water absorption quantity is decreased according to the mixing ration by using this mixture. A compressor with excellent durability using tetrafluoroethane for the refrigerant can be obtained.
