机械冷库这种贮藏水果的办法是在良好的绝热建筑物中，装有机械冷库机组，并根据水果品种对贮藏温度、湿度和通风换气的要求，对冷库系统进行人为的调节和控制，因而贮藏时间更长，效果更好。食品冷库
Mechanical refrigerator this fruit storage method is in good thermal insulation building, equipped with mechanical cold storage unit, and according to the fruit varieties of storage temperature, humidity and ventilation requirements, artificial regulation and control, to cold storage system and storage time is longer, the better.
机械冷库冷藏的原理，机械冷库是利用气化温度很低的液体（制冷剂），使它在低压下蒸发变成气体，从而吸收热量，达到降温的目的。
Machinery the principle of cold storage refrigeration, cold storage is the use of gasification temperature is very low liquid (refrigerant), make it evaporate under low pressure gas, which absorbs heat, to achieve the purpose of cooling.
冷库用制冷剂除了沸点低之外，还要求对人体器官无害，对金属不起腐蚀作用，无燃烧及爆炸的危险，不与润滑剂起化学反应，还应具 备良好的吸热性能，蒸发吸热多，在高压冷凝系统内压力低，粘度较低和价格便宜等。
Cold storage with refrigerant in addition to the low boiling point, harmless to human organs, are also required to corrode the metal, no combustion and explosion danger, no chemical reaction with the lubricant and also required for performance of heat absorption, the evaporation heat absorption, low pressure in high-pressure condensate system, such as low viscosity and low price.
