摘　　要：介绍了变排量压缩机的调节机理以及压缩机调节性能试验装置 ,给出了空调负荷渐变以及不同压缩机转速情况下活塞行程、制冷剂质量流量等参数的变化规律 ,对活塞行程变化时需要的摇板箱和吸气压力差值与活塞行程变化方向、活塞行程大小以及压缩机转速的关系进行了分析。The regulating mechanism and test system are introduced, and then how the piston stroke length and refrigerant mass flow rate change when the cooling load varies gradually and at different compressor rotary speeds is given, and finally the relations between the critical differential of wobble-plate case pressure and suction pressure to drive the piston stroke length to change and the compressor rotary speed, the piston stroke length, the changing direction of piston stroke length are analyzed
