食品冷庫主要用作對干貨、乳制品、肉類、禽蛋、水產海鮮、水果、蔬菜、酒類、冷飲、冷凍食品等生鮮食品恒溫貯藏。食品冷庫可廣泛應用于食品廠、乳品廠、食堂、果蔬倉儲、禽蛋倉儲、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.
食品冷庫民以食為天，是關系國計民生的至要產業，促進生鮮食品冷庫鏈發展，對發展農村經濟和擴大對外貿易發揮物重要作用。食品冷庫利用氣化溫度很低的液體作為冷卻劑，使其在低壓和機械控制的條件下蒸發，吸收貯藏庫內的熱量，從而達到冷卻降溫達到食品保鮮目的。
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.
小型食品冷庫的承重結構一般為梁板式結構，而大型多層食品冷庫多采用現澆鋼筋混凝土無梁樓蓋結構。近年來，預制裝配式的無梁樓蓋與用升板法施工的無梁樓蓋框架結構正在逐步推廣。冷庫的圍護墻體結構設計除滿足強度和穩定性外，還應保持絕熱層及隔氣層的連續性，使之符合建筑熱工要求。冷庫的屋面結構受太陽直接照射的時間較長，受氣溫變化的影響，會產生膨脹或收縮變形，宜采用預制構件，使變形在構件之間進行調整，從而減小總變形。為了防止因屋面伸縮對墻體產生的不利影響，可在屋面結構與墻體之間設計成滑動接觸面。
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.
