制冷节能有两方面的工作。一是制取等量的冷量所消耗的能量较少,这是利己式的;二是消耗等量的能量,除制取等量的冷量外,还能回收制冷过程中的废热供它用,这是利它式的。净输出功与净输入功之比为设备的特性系数,只制冷的制冷机的特性系数仅为5左右;将制冷过程中的废热全部回收利用,制冷机的特性系数就可达10左右。一、系统布置利它式制冷节能主要是回收冷凝热。系
There are two aspects of cooling and energy saving. First, less energy is consumed to produce the same amount of cold, which is self-serving; second, it consumes the same amount of energy, and in addition to making the same amount of cold, it can also recover the waste heat from the refrigeration process. Use, this is altruistic. The ratio of the net output power to the net input power is the characteristic coefficient of the equipment, and the characteristic coefficient of only the refrigerating refrigerator is only about 5; all the waste heat in the refrigerating process is recycled, and the characteristic coefficient of the refrigerating machine can reach about 10. First, the system layout, it’s cooling energy is mainly recycled heat recovery. system
