摘　　要：分析了润滑油粘度对冰箱压缩机功率消耗的影响,探讨了冰箱压缩机活塞与气缸间隙对其润滑与密封的影响。通过试验证明,在合理的活塞与气缸间隙下,将通常所用的润滑油改为更低粘度的润滑油,不仅可以显著提高冰箱压缩机的性能指标,而且满足可靠性的要求。This paper analyzes the influence of the lubricant viscosity on energy consumption of refrigerator's compressor,and investigates the effects of the clearance between piston and cylinder on lubrication and seal.The experiments indicate that the performance of the refrigerator's compressor will be improved and the reliability can be satisfied when the low viscosity lubricant is used under reasonable clearance between piston and cylinder.
