| 摘 要： | 空调系统的设备按设计负荷配置,但大部分时间都处于低于设计负荷下运行,增加了无效的能耗。电机长期工作在低负荷时的效率和功率因数均较低,降低了空调机组的性能系数COP,增加了空调机组的能耗。因此,用电子膨胀阀来调节制冷系统的制冷量,从而使系统运行的能耗减少是具有意义并且是可行的。

| Abstract: | Air conditioning system was equiped based on design load.The invalid energy consumption increased bacause of its operation under the load at major time.The property coefficient COP of air conditioner system reduced and its consumption increased when the electrical motor operated at lower load.The energy consumption could be reduced through adjusting cooling capacity with an electronical expansion valve. |
