2、性强：主机选用博泽冷库ZB涡旋全封闭或半封闭活塞制冷压缩机，震动低、噪音小、运行可靠，使用铜管铝片式散热器，换热、使用寿命长。

Cold storage machine unit is composed of compressor, condenser, evaporator and other components. The compressor is the core of the unit, and its purpose is to compress refrigerant to form high temperature and high pressure gas, which is sent to the condenser, cooled and condensed into liquid, and then sent to the evaporator through the throttling device. In the evaporator, the liquid refrigerant absorbs heat from the cold storage room and evaporates into gas. The gas is sent to the compressor again by the circulation of the refrigerant, and the cold medium of the refrigeration cycle is formed.

冷库机组由压缩机、冷凝器、蒸发器等组件组成。压缩机是该机组的核心，其目的是将制冷剂压缩成高温高压气体，送入冷凝器冷却凝结成液体，再经节流装置送入蒸发器。在蒸发器中，液体制冷剂吸取冷库室的热量蒸发成气体，气体又经制冷循环而送回压缩机，形成制冷循环的冷媒。

⑤需冷藏的材料应尽快下库，尽量削减耽搁时刻；对经过初加工的材料进行冷藏，运用保鲜纸包裹并装入合适洁净盛器，以避免污染和干耗。
