| 摘 要： | 根据研究对象不同，制冷系统稳定性可分为蒸发器完全蒸干点随机振荡现象研究，蒸发和热力膨胀阀控制回路稳定性研究和定容量制冷系统稳定性研究三个阶段，对变排量压缩机汽车空调制冷系统的稳定性问题进行了初步分析，指出该系统中两个流量调节装置存在相互之间的参数耦合和调节协调问题，根据系统使用情况及其非线性的特点，可将变排量压缩机汽车空调制冷系统稳定性划分为小扰动3稳定性和大扰动稳定性。

| Abstract: | According to different study objects,study on stability of refrigerating system is divided into three phrases:Study on random vibration of the fully dried out point of evaporators,study on stability of control loop of evaporators and thermo-expansion valves and study on stability of constant-capacity refrigerating system.Stability of the automotive refrigerating system with a variable-displacement compressor is initially analyzed.It is pointed out that there are two flow regulating units in the sys-tem and brings in parameter coupling and harmony regulating between them.According to condition of system service and its nonlinear features,stability of automotive refrigerating systems with variable-displacement compressors is divided into the small perturbation stability and the large perturbation stability. |
