食品冷库主要用作对干货、乳制品、肉类、禽蛋、水产海鲜、水果、蔬菜、酒类、冷饮、冷冻食品等生鲜食品恒温贮藏。食品冷库可广泛应用于食品厂、乳品厂、食堂、果蔬仓储、禽蛋仓储、酒店、超市等。
Food cold storage is mainly used for the storage of dry goods, dairy products, meat, eggs, seafood, fruits, vegetables, wine, beverage, frozen food, fresh food and constant temperature. Food storage can be widely used in food plants, dairy plants, canteens, fruits and vegetables storage, warehousing, hotels, supermarkets and other eggs.
食品冷库民以食为天，是关系国计民生的至要产业，促进生鲜食品冷库链发展，对发展农村经济和扩大对外贸易发挥物重要作用。食品冷库利用气化温度很低的液体作为冷却剂，使其在低压和机械控制的条件下蒸发，吸收贮藏库内的热量，从而达到冷却降温达到食品保鲜目的。
People on food cold storage food is relation the national economy and the people's livelihood to industry and to improve the fresh food cold chain development, to the economic growth of rural areas and expand foreign trade play an important role. The food cold storage uses the liquid as the coolant to evaporate under the condition of low pressure and mechanical control, and absorbs the heat in the storage reservoir, so as to achieve the goal of keeping food fresh.
小型食品冷库的承重结构一般为梁板式结构，而大型多层食品冷库多采用现浇钢筋混凝土无梁楼盖结构。近年来，预制装配式的无梁楼盖与用升板法施工的无梁楼盖框架结构正在逐步推广。冷库的围护墙体结构设计除满足强度和稳定性外，还应保持绝热层及隔气层的连续性，使之符合建筑热工要求。冷库的屋面结构受太阳直接照射的时间较长，受气温变化的影响，会产生膨胀或收缩变形，宜采用预制构件，使变形在构件之间进行调整，从而减小总变形。为了防止因屋面伸缩对墙体产生的不利影响，可在屋面结构与墙体之间设计成滑动接触面。
The load-bearing structure of the small-scale cold storage food general for beam slab structure, and the large-scale multi-storey food cold storage the cast-in-place reinforced concrete girderless floor structure. In recent years, prefabricated beamless roof and lift slab construction girderless floor frame structure was gradually extended. In addition to the strength and stability of the wall structure of the cold storage, the continuity of the insulation layer and the air separation layer should be kept, so that it can meet the requirements of the building thermal engineering. Cold storage roof structure by the direct rays of the sun for a long time, affected by the temperature change, will produce the expansion or shrinkage deformation, should adopt the prefabricated, deform in component is adjusted, thereby reducing the total deformation. In order to prevent the adverse effect caused by the expansion of the roof to the wall, the sliding contact surface can be designed between the roof structure and the wall body.
