Abstract of the Disclosure The invention relates to refrigeration of machine oil to be used in a sealed motor-compressor unit of a refrig- eration apparatus, such as an electric refrigerator, an electric cold-storage box, a small-scale electric refrig- erated show-case, a small-scale electric cold-storage show-case and the like. The oil has a specifically enhanced property, by which a small initial power consumption is required by the sealed motor-compressor and an easy supply of a predetermined amount of the refrigerating machine oil to the refrigerating system is ensured even when the ambient temperature is low. The oil consists of low volatile distillates of naphthenic type oil, in which the kinetic viscosity is within 7.0 to 13.0 cst. at a temperature of 100°F and within 2.0 to 2.5 cst. at a temperature of 210°F, with a seizure load of more than 450 lbs. according to the falex test.
