Lubricating oil for refrigerator with compressor

Abstract

A lubricating oil for a compression-type refrigerator which comprises, as a main component, at least one polyoxyalkyleneglycol derivative represented by the general formula: wherein R¹ is an alkyl group having 1 to 10 carbon atoms, an acyl group having 1 to 10 carbon atoms or an aliphatic hydrocarbon group having 2 to 6 valencies, R² is an alkylene group having 2 to 4 carbon atoms, R³ is an alkyl group having 1 to 10 carbon atoms, or an acyl group having 1 to 10 carbon atoms, n is an integer of 1 to 6, and m is an integer of 1 to 80. The invention also is directed to the use of a polyoxyalkyleneglycol derivative as a lubricant for compression-type refrigerators in which 1,1,1,2-tetraluoroethane is used as a refrigerant, and a method for effecting lubrication in such refrigerators, and a compression-type refrigerator system.
