機械冷庫這種貯藏水果的辦法是在良好的絕熱建筑物中，裝有機械冷庫機組，并根據水果品種對貯藏溫度、濕度和通風換氣的要求，對冷庫系統進行人為的調節和控制，因而貯藏時間更長，效果更好。食品冷庫
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.
機械冷庫冷藏的原理，機械冷庫是利用氣化溫度很低的液體（制冷劑），使它在低壓下蒸發變成氣體，從而吸收熱量，達到降溫的目的。
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.
冷庫用制冷劑除了沸點低之外，還要求對人體器官無害，對金屬不起腐蝕作用，無燃燒及爆炸的危險，不與潤滑劑起化學反應，還應具 備良好的吸熱性能，蒸發吸熱多，在高壓冷凝系統內壓力低，粘度較低和價格便宜等。
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.
