摘要： The present invention relates to a refrigerating machine oil composition, which is composed of a base oil as a main component containing a single component of a compound or a mixture of compounds selected from the group consisting of cyclic carbonates and aliphatic carbonate derivatives. For example, the refrigerating machine oil composition is characterized by that the single component of a compound or the mixture of compounds selected from the group consisting of cyclic carbonates and aliphatic carbonate derivatives are expressed by the following general chemical formulas for cyclic carbonates (1) and aliphatic carbonate derivatives (2): (R1, R2 in the formula (1) respectively and independently express a hydrogen atom or a fluorine atom or an alkyl having a carbon number of 1 to 4, or a perfluoroalkyl having a carbon number of 1 to 3. Therein, R1 and R2 may be the same or different from each other. R3, R4 in the formula (2) respectively and independently express an alkyl having a carbon number of 1 to 4 or a perfluoroalkyl having a carbon number of 1 to 3. Therein, R3 and R4 may be same or different from each other.) An object of the present invention is to provide a refrigerating machine oil having an excellent wear resistance, a refrigeration system working medium and a refrigeration system using the refrigerating machine oil, and a compressor used in the refrigeration system.
