There is provided a refrigerating machine oil composition which has a low viscosity, an improved energy saving performance, a good sealability and an excellent loading endurance and, therefore, can be suitably used in various refrigerating application fields, in particular, in closed-system refrigerators. The refrigerating machine oil composition of the present invention comprises a base oil containing a hydrogenated α-olefin oligomer as a main component and having a kinematic viscosity of 1 to 8 mm 2 /s as measured at 40° C., and is preferably applied to refrigerators having a sliding portion which is made of an engineering plastic material, or provided thereon with an organic coating film or an inorganic coating film. |
