Abstract
Official abstract text for this publication.
The present invention provides a refrigerating machine oil comprising: an ester of a polyhydric alcohol and a fatty acid as a base oil; and an ether compound of a polyhydric alcohol, the refrigerating machine oil being used with an unsaturated hydrofluorocarbon refrigerant.
First claim
Opening claim text (preview).
The invention claimed is: 1. A working fluid composition for a refrigerating machine comprising: a refrigerating machine oil; and an unsaturated hydrofluorocarbon refrigerant, wherein the refrigerating machine oil comprises: an ester of a polyhydric alcohol and a fatty acid as a base oil; and an ether compound of a polyhydric alcohol having 3 to 6 hydroxy groups. 2. The working fluid composition for a refrigerating machine according to claim 1 , wherein the unsaturated hydrofluorocarbon is at least one selected from 1,3,3,3-tetrafluoropropene and 2,3,3,3-tetrafluoropropene. 3. The working fluid composition for a refrigerating machine according to claim 1 , wherein the ether compound is a compound represented by the following formula (1): wherein R 1 , R 2 , and R 3 each independently represent a hydrogen atom, a C1 to C22 alkyl group, an alkenyl group, or an aryl group, and wherein at least one of R 1 , R 2 , and R 3 represents the group other than a hydrogen atom. 4. The working fluid composition for a refrigerating machine according to claim 1 , wherein a content of the ether compound is 0.4% by mass or less based on a total amount of the refrigerating machine oil. 5. The working fluid composition for a refrigerating machine according to claim 1 , wherein the ether compound is a monoether compound.
