摘要
制冷系统在循环过程中,压缩机在运行时会有部分热量通过壳体以对流和传导方式散失在周围环境中,这部分热量可用来对风冷冰箱、热泵装置蒸发器进行除霜、冰箱食物解冻、热泵装置的强化制热等,而制冷系统制冷时,大量冷凝热被排放到环境中,造成能源浪费,增加了环境温度,对冷凝热重新利用不仅可以减少环境热污染,也是一种变废为宝的节能方法,冷凝热的利用主要有风冷冰箱、热泵装置的除霜;加热生活用水和生产热水等。冰箱、热泵系统的余热利用作为一项能源技术研究,在合理利用能源的基础上可有效实现节约能源的效益。
During the operation of the compressor, part of the heat is lost through the casing through convection and conduction in the surrounding environment. This part of the heat can be used to defrost air-cooled refrigerators and heat pump evaporators;refrigerator food thaw;heat pump unit for enhanced heating, etc. When the refrigeration system is operating, a large amount of condensation heat is discharged into the environment, causing waste of energy, increasing the ambient temperature, and reusing the condensation heat can not only reduce environmental heat pollution, but also an energy-saving method that turns waste into treasure. The use of condensation heat mainly includes defrosting of air-cooled refrigerators and heat pump devices;heating of domestic water and production of hot water, etc. The waste heat utilization of refrigerators and heat pump systems is an energy technology research, and the energy-saving benefits can be effectively realized on the basis of rational use of energy.
