The present invention provides a refrigerator oil composition including: a base oil (A) composed of at least one selected from a polyalkylene glycol, a polyol ester, a poly-alpha-olefin, an alkylbenzene, and an mineral oil; an organic sulfur compound (B) having a sulfur content of 35% by mass or less; and a refrigerant (C) composed of at least one selected from carbon dioxide gas, a hydrocarbon, and ammonia, in which the refrigerator oil composition has a total sulfur content of 0.01 to 0.1% by mass with respect to a total amount of the components (A) and (B). The refrigerator oil composition is novel, and is free from an environmental problem such as the ozone layer destruction or the global warming, can retain its lubrication property for a long period of time, and does not cause the clogging of a capillary in a refrigeration cycle.
