1.蒸发器:蒸发器是一个换热设备,制冷剂液体在蒸发器里吸热汽化,在此过程中对其周围的环境产生制冷效应。制冷剂在蒸发器里汽化过程是等压下的沸腾过程,沸腾温度是该压力下的饱和温度,即沸点。因此,把蒸发器称为“沸腾器”更为确切,但制冷工程中习惯上都称为蒸发器。蒸发器内制冷剂沸腾的压力称为蒸发压。力P0,相对应的饱和温度(沸点)称为蒸发温度t0,沸腾汽化过程称为蒸发过程。

2.压缩机:压缩机是从蒸发器中抽吸出制冷剂蒸汽并对其进行压缩的设备。它的功能有:

3.冷凝器:冷凝器是一个换热设备,制冷剂在其内凝结并释放出热量,这些热量由空气或水带走。冷凝器中用于冷却制冷剂蒸发并带走凝结时放出的热量的介质称为“冷却剂”或“冷却介质”,对于水就称为冷却水。冷凝器中的冷凝过程是等压过程,其中制冷剂压力称为冷凝压力pk,,对应的饱和温度称为冷凝温度tk。

4.节流机构:节流机构的功能有:
