Abstract
The present invention provides a refrigerating machine oil comprising a hydrocarbon-based base oil having a viscosity index of 120 or less, and the refrigerating machine oil being used with a 1-chloro-2,3,3,3-tetrafluoropropene refrigerant.
Claims6
A refrigerating machine oil comprising a hydrocarbon-based base oil,
- the refrigerating machine oil having a viscosity index of −30 to 105, and being used with a 1-chloro-2,3,3,3-tetrafluoropropene refrigerant, wherein
- the hydrocarbon-based base oil is at least one paraffinic mineral oil-based hydrocarbon oil,
- the hydrocarbon-based base oil has a viscosity index of −30 to 105, a % CP of 63 to 90, and a % CN of 13 to 40, and
- an amount of the hydrocarbon-based base oil is 95 mass % or more based on the total amount of refrigerating machine oil.
