摘　　要：分析了影响压缩机COP值因素。采用无限位吸气阀片及钢制薄阀板,使用半直接吸气方式及消音器,优化吸气通道及缸头部分的传热以及阀板吸、排气孔孔径、内排气管管径等措施提高压缩机的压缩效率。采用细曲轴及平面滚动轴承技术及较低粘度的冷冻油以提高机械效率。采用优化电容器的RSCR电机,选用高磁感低损耗硅钢片,增加定子高度并通过增大主线圈等方法优化电机设计。提出了机件加工精度、运动部件配合间隙及阀组气密性检测要求以及电机定转子装配工艺要求。在实验对比基础上研制的R600a压缩机COP值达1.75。The factors influencing the COP of compressors were analyzed The compression efficiency was increased by adopting the non - valve guard suction reed valve and thin steel valve plate, using semi- direct suction manner and muffler, optimizing heat transfer of the suction inlet and cylinder head, and changing the diameters of the suction hole and discharge hole of the valve plate and inner - discharge pipe. Applying the slender crankshaft, the level rolling bearing technology, and lower viscosity refrigeration oil, increased the mechanical efficiency. The design of the motor was optimized by adopting RSCR motor with optimizing capacitor design, using high magnetic strength and low dissipation silicon - steel sheet, raising the height of stator, and increasing the main coil. The processing accuracy of the component, the fit - up gaps of the moving parts, the requirements of gas tightness detection, and the fit - up technology of the rotors and stators were proposed. The experiments and comparisons show that the COP of this newly developed R600a compressor can reach 1.75.
