FIELD: chemistry.
SUBSTANCE: claimed invention relates to a composition of a working liquid for a refrigerating machine, and it contains oil for refrigerating machines, containing a mixture of at least two esters, selected from a group of esters of at least one multi-atomic alcohol, and a fatty acid with content of C5-C9 fatty acid 50-100% mol, a fluoropropene refrigerant and/or trifluoroiodine methane refrigerant (versions).
EFFECT: obtaining oil for refrigerating machines, which has sufficient thermal and chemical stability in the presence of the fluoropropene refrigerant and/or trifluoroiodine methane refrigerant, and simultaneously sufficiently compatible with refrigerants.
