    摘要: PROBLEM TO BE SOLVED: To provide a refrigerator oil and a working fluid composition for a refrigerator which are capable of achieving a high level of refrigerant compatibility in refrigeration systems employing fluoropropene refrigerants.SOLUTION: A working fluid composition for a refrigerator comprises: a polyalkylene glycol represented by the general formula (1) defined by R-(OR)-OR; and a fluoropropene refrigerant. The peroxide number of the polyalkylene glycol is 10.0 meq/kg or less. [In the formula, Rand Rmay be identical or different and each represent hydrogen, a C1-C5 alkyl group or a C2-C5 acyl group, Rrepresents a C2-C4 alkylene group, n represents the number of repeats of the oxyalkylene group represented by OR, and the proportion of C2 alkylene groups to all Ris 30 mol% or less.]
