本文提出了一种提高压缩机性能系数的新方法。 富勒烯（C70）和NiFe2O4纳米复合材料通过跨距80进行了改性，并通过固体研磨（SG）分散在冷冻机油中。此外，使用四球摩擦测试仪研究了纳米复合材料的摩擦学性能。结果表明，当富勒烯纳米复合材料的质量浓度高于60 ppm并且纳米油的浓度为2 g / L时，摩擦系数从0.13降低至0.06，这意味着磨损减少。 在空调测试条件下，压缩机的性能系数可以提高1.23％。
Abstract：
A novel way for a compressor to improve its coefficient of performance was proposed in this paper. Fullerenes (C70) and NiFe2O4 nanocomposites were modified by span 80 and dispersed in refrigeration oil by solid grinding (SG). Besides, the tribological properties of the nanocomposites were investigated using a four ball friction tester. The results show that when the mass concentration of fullerenes nanocomposite is higher than 60 ppm and the concentration of nano-oil is 2 g/L, the friction coefficient decreases from 0.13 to 0.06 which means the wear is reduced. The coefficient of performance of the compressor under the air conditioning test condition can be raised by 1.23%.
