设计冷库时,常根据库内热平衡来选择冷分配设备并计算设备(蒸发器)表面积;常根据蒸发器的传热系数和(库内空气和制冷剂蒸发温度)温差来进行热平衡计算。温差常取8—12℃。 多种因素影响库内热交换。如产品(指冷库中储藏的食品,以下简称产品)的种类和数量、包装物的材料及包装形式、库内装载量的大小、堆放密度、产品内部和外部的
In the design of cold storage, the cold distribution equipment is often selected according to the heat balance in the storage and the surface area of the equipment (evaporator) is calculated. The heat balance calculation is usually performed according to the heat transfer coefficient of the evaporator and the temperature difference between the air in the store and the evaporation temperature of the refrigerant. Temperature difference often take 8-12 ℃. A variety of factors affect the heat exchange within the bank. Such as product (refers to the cold storage of food products, hereinafter referred to as the type of product) and the number of packages of materials and packaging, the size of the library load, stacking density, internal and external products
