Provided is a refrigerating machine oil composition including a base oil which contains at least one substance selected from the group consisting of monoether compounds, alkyleneglycol diethers, and polyoxyalkyleneglycol diethers having an average repetition number of an oxyalkylene group of 2 or less as a main component, and has a kinematic viscosity at 40°C of 1 to 8 mm2/s. The refrigerating machine oil composition is preferably applied to refrigerators whose sliding parts are composed of an engineering plastic or provided with an organic coating film or an inorganic coating film. The refrigerating machine oil can improve energy-saving performance due to its low viscosity, has high sealing property and excellent load capacity, and is suitably used in various refrigeration applications, especially in closed-type refrigerators.
本发明提供了一种冷冻机油组合物,其中包括一种基础油,该基础油含有至少一种从单醚化合物、亚烷基乙二醇二醚和具有氧亚烷基平均重复数为 2 或更少的聚氧亚烷基乙二醇二醚组成的组中选出的物质作为主要成分,并且在 40°C 时的运动粘度为 1 至 8 mm2/s。冷冻机油组合物最好用于滑动部件由工程塑料组成或带有有机涂层膜或无机涂层膜的冰箱。这种冷冻机油粘度低,密封性高,承载能力强,可提高节能性能,适用于各种冷冻应用,特别是封闭式冰箱。
