以水为对象作了多组实验,对真空冷却机理进行探讨并对盘管热负荷进行了分析,文章指出真空预冷过程中凝水器盘管温度可能升高。研究表明,当凝水器盘管温度很低时可以关闭制冷机以节约能源。
A series of experiments were made on the basis of water. The vacuum cooling mechanism was discussed and the heat load of the coil was analyzed. The article pointed out that the temperature of the condenser coil may increase during the process of vacuum precooling. Research shows that the cooler can be turned off to save energy when the condenser coil temperature is low.
