Title:
WORKING FLUID COMPOSITION FOR REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2014/156737
Kind Code:
A1
Abstract:
The present invention provides a working fluid composition for a refrigerator, said working fluid composition including: tetrafluoropropene as a refrigerant; and a refrigerator oil including, as a base oil, a mixed ester obtained by mixing a complex ester (A), which is synthesized from a prescribed polyalcohol, a C6-12 polybasic acid, and a C4-18 monovalent alcohol or a C4-18 monovalent fatty acid, with a polyol ester (B), which is synthesized from a prescribed polyalcohol and a C4-18 monovalent fatty acid, at a mass ratio (the complex ester (A)/the polyol ester (B)) in the range of 5/95 to 95/5. The viscosity of the dissolved refrigerant at a temperature of 80˚C and an absolute pressure of 1.6 MPa is at least 1.5 mm2/s.
