摘要： The present disclosure provides a refrigerant composition comprising a refrigerant containing a fluorinated hydrocarbon, and having improved sliding properties for the sliding portions of vapor-compression refrigerating machines.
Specifically, the present disclosure provides a refrigerant composition comprising a refrigerant containing a fluorinated hydrocarbon, and an oligomer that is a polymer of a halogenated hydrocarbon,



wherein
(1) the fluorinated hydrocarbon comprises fluorinated ethylene, and
(2) the oligomer is at least one of an oligomer A having a molecular weight of 200 to 900 that is a polymer of a halogenated hydrocarbon A represented by C2HaFbClc, wherein a+b+c=4, a represents an integer of 0 to 3, b represents an integer of 1 to 4, and c represents an integer of 0 to 1, and an oligomer B having a molecular weight of 200 to 900 that is a polymer of a halogenated hydrocarbon B represented by C3HaFbClc, wherein a+b+c=6, a represents an integer of 0 to 3, b represents an integer of 3 to 6, and c represents an integer of 0 to 1.
