摘要:
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.

PROBLEM TO BE SOLVED: To provide a novel refrigerant composition that brings an inherent feature that meets the requirement of a low or zero ozone depletion potential and a lower global warming potential compared with a present refrigerant, and to provide a heat transfer fluid composition.SOLUTION: The present invention relates to fluoroolefin compositions. The fluoroolefin compositions are useful as refrigerants or heat transfer fluids and in processes for producing cooling or heat. Additionally, the fluoroolefin compositions may be used to replace currently used refrigerant or heat transfer fluid compositions that have higher global warming potential.

PROBLEM TO BE SOLVED: To solve problems found, when a single refrigerant of C 3 H m F n refrigerant is used, by using a refrigerant mixture of a proper composition ratio to which a HFC refrigerant is added, or by using a refrigerant mixture in which a specific refrigerant excluding HFC refrigerant is mixed, in a refrigerating apparatus that uses the refrigerant including a refrigerant represented by a molecular formula 1:C 3 H m F n (wherein m and n each is integers of 1-5, with m+n=6), and having one double bond in the molecular structure. SOLUTION: This refrigerating apparatus 20 employs the refrigerant mixture including 70-94 mass% of C 3 H m F n refrigerant represented by molecular formula 1: C 3 H m F n (wherein m and n each is an integer of 1-5, with m+n=6) and having one double bond in the molecular structure and a HFC refrigerant of 6-30 mass%, a refrigerant mixture including the C 3 H m F n refrigerant and a specific refrigerant, e.g., a hydrocarbon, or a refrigerant mixture including 2,3,3,3-tetrafluoro-1-propene and carbon dioxide.
