There are provided a refrigerating oil for refrigerant compositions in which good lubricity can be achieved when a refrigeration cycle is performed using a refrigerant having a sufficiently low GWP, a method for using the refrigerating oil, and use of the refrigerating oil. The refrigerating oil for a refrigerant composition contains a refrigerant containing trans-1,2-difluoroethylene (HFO-1132(E)), trifluoroethylene (HFO-1123), and 2,3,3,3-tetrafluoro-1-propene (R1234yf).
本发明提供了一种用于制冷剂组合物的冷冻机油,当使用具有足够低全球升温潜能值的制冷剂进行制冷循环时,该冷冻机油可以实现良好的润滑性;还提供了一种使用该冷冻机油的方法以及该冷冻机油的用途。用于制冷剂组合物的冷冻机油含有反式-1,2-二氟乙烯(HFO-1132(E))、三氟乙烯(HFO-1123)和 2,3,3,3-四氟-1-丙烯(R1234yf)。
