Title:
REFRIGERATING MACHINE OIL, WORKING FLUID COMPOSITION FOR REFRIGERATING MACHINE, AND METHOD FOR PRODUCING REFRIGERATING MACHINE OIL
Document Type and Number:
WIPO Patent Application WO/2021/221060
Kind Code:
A1
Abstract:
One aspect of the present invention provides a refrigerating machine oil containing a mixed base oil of a first hydrocarbon base oil having a kinematic viscosity at 40°C of less than 6 mm2/s and a second hydrocarbon base oil having a kinematic viscosity at 40°C of 6 mm2/s or higher, wherein (A)/(B) is greater than 1 and no greater than 1.5, where (A) is the kinematic viscosity at 40°C of the mixed base oil and (B) is the kinematic viscosity at 40°C of the first hydrocarbon base oil.
