Disclosed is a refrigerator oil composition which has a low viscosity, can achieve the improvement in energy conservation, shows a good sealing property, is excellent in load bearing property, and can be suitably used in various refrigeration fields, particularly in a hermetic refrigerator. A refrigerator oil composition comprising a hydride of an α-olefin oligomer as the main ingredient and a base oil having a kinetic viscosity of 1 to 8 mm2/s at 40˚C. The composition is preferably applied to a refrigerator which has a slide section made of an engineering plastic or having an organic or inorganic coating film. |
