四、冷凝器离开压缩机的热的制冷剂气体中包含有在蒸发器中吸收的热量,同时也包含着压缩热,并且在有些情况下还包含着大部分电动机热损失。这种制冷剂气体的压力是很高的,从而使发生大量传热的饱和温度(在冷凝器中的冷凝温度)相应的比较高,因此热量就能传给较低温度的冷却介质。 Fourth, the condenser The hot refrigerant gas leaving the compressor contains the heat absorbed in the evaporator, but also contains the heat of compression, and in some cases also contains most of the motor heat loss. The pressure of such refrigerant gas is so high that the saturation temperature at which large amounts of heat transfer occur (the condensation temperature in the condenser) is correspondingly high so that heat can be transferred to the lower temperature cooling medium.
