Provided is a grease for a refrigerating machine oil which is difficult to be compatible with a refrigerant and hardly flows into the refrigerant. The grease for a refrigerating machine oil includes a hydrocarbon oil, a resin having a melting point of 270°C or lower, and in which an unworked penetration is 100 to 340 at 25°C.
本发明提供了一种难以与制冷剂相容且几乎不流入制冷剂的冷冻机油润滑脂。冷冻机油润滑脂包括碳氢化合物油、熔点为 270°C 或更低的树脂,在 25°C 时其未加工渗透率为 100 至 340。
