Abstract
The present invention provides a highly stable HFO refrigerant composition for use in a vapor compression-type refrigeration system, having improved slidability for the sliding portions of the vapor compression-type refrigeration system. More specifically, the present invention provides an HFO refrigerant composition comprising at least one type of HFO refrigerant and a polymer of halogenated propene represented by C3HaFbClc (provided that a+b+c=6, a=an integer of 1 to 3, b=an integer of 3 to 5, and c=an integer of 0 to 1) that is an oligomer having a molecular weight of 200 to 900.
Claims5
A method of improving slidability in a member selected from the group consisting of mobile air conditioners, refrigerators, turbo freezers, container freezers, household air conditioners, and industrial air conditions, comprising
- combining an HFO refrigerant composition comprising at least one type of HFO refrigerant and a polymer of halogenated propene represented by C3HaFbClc (provided that a+b+c=6, a=an integer of 1 to 3, b=an integer of 3 to 5, and c=an integer of 0 to 1) that is an oligomer having a molecular weight of 200 to 900 with the member described above.
