三、空调器工作原理空调器主要由制冷循环系统与风路系统两大部分组成。制冷循环系统是由全封闭压缩机、蒸发器、冷凝器、毛细管及其连接管道构成。系统内充以氟利昂22(F-22)制冷剂,只要不泄漏,就不必添加制冷剂;风路系统又由离心风扇、轴流风扇、风扇电动机及风道等组成。窗式空调器工作原理见图5所示。 Third, the working principle of air conditioners Air conditioners mainly by the refrigeration cycle system and the wind system consists of two parts. The refrigeration cycle system consists of a totally enclosed compressor, an evaporator, a condenser, a capillary tube and its connecting pipes. The system is filled with Freon 22 (F-22) refrigerant, so long as it does not leak, there is no need to add refrigerant; the air system consists of centrifugal fans, axial fans, fan motors and ducts. The window air conditioner works as shown in Figure 5.
