Abstract
A working fluid composition containing a refrigerating machine oil containing at least one base oil selected from the group consisting of polyvinyl ether, polyalkylene glycol, and polyol ester, and a refrigerant containing trans-1,2-difluoroethylene (HFO-1132 (E)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf).
Claims15
A working fluid composition comprising:
- a refrigerating machine oil comprising at least one base oil selected from the group consisting of a polyvinyl ether, a polyalkylene glycol, and a polyol ester;
- and
- a refrigerant comprising trans-1,2-difluoroethylene (HFO-1132 (E)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf).
A refrigerating machine oil comprising at least one base oil selected from the group consisting of a polyvinyl ether, a polyalkylene glycol, and a polyol ester, and
- being used together with a refrigerant comprising trans-1,2-difluoroethylene (HFO-1132 (E)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf).
A refrigerating machine comprising:
- a refrigerant circulation system comprising a compressor, a condenser, an expansion mechanism, and an evaporator,
- wherein the refrigerant circulation system is filled with a refrigerating machine oil comprising at least one base oil selected from the group consisting of a polyvinyl ether, a polyalkylene glycol, and a polyol ester, and a refrigerant comprising trans-1,2-difluoroethylene (HFO-1132 (E)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf).
