Please tell me about how dose an air condition system work.Thanks.

氟利昂22...R22是常用的中温制冷剂.在1个大气压下,沸点为-40.8℃,临界温度是96.0℃,凝固点为-160.0℃.
为什么先说临界温度,这就是气体的状态特性.
在临界温度至上,气体无论多大压力都不能液化.
而气态的氟利昂,经过压缩,就会升温,在冷凝器中临界温度之下就成为液态氟利昂,贮存于罐中.
和冷凝器相连接的是毛细管,就是这个毛细管,才能够让储液罐保持压力.液态的氟利昂通过毛细管和输液管,进入空调的室内蒸发器,由于压力降低,氟利昂蒸发吸热,降低温度,由风扇吹出冷风.
气化后的氟利昂,被压缩机吸入,再压缩、发热、冷却液化、储存,毛细管,输液管,蒸发吸热,周而复始,就形成了一个制冷过程.
如果用换向阀将过程反向,就是冷暖空调的制热过程.
这个过程就是利用热泵原理,就是用机械能让热量搬家.
