A lubricating oil for compression-type refrigerator includes, as a main component, a polyoxyalkyleneglycol derivative represented by the general formula: n R 1 —[—(OR 2 )m—OR 3 ]n n wherein R1 is a methyl group, R2 is a propylene group, R3 is a methyl group, n is an integer of 1 and m is an integer of 12 to 80, and 1,1,1,2-tetrafluoroethane. The derivative has a kinematic viscosity of 5 to 50 cSt at 100° C. |
