冷库主要用于食品的冷冻加工及冷藏,它通过人工制冷,使室内保持一定的低温。冷库的墙壁、地板及平顶都敷设有一定厚度的隔热材料,以减少外界传入的热量。为了减少吸收太阳的辐射能,冷库外墙表面一般涂成白色或浅颜色。因而冷库安装与一般工业和民用安装不同,有它独特的结构。
Cold storage is mainly used for food freezing and cold storage, it is through artificial refrigeration, so that the room to maintain a certain low temperature. Cold storage walls, floors and flat top are equipped with a certain thickness of thermal insulation materials to reduce the heat of the outside world. In order to reduce the radiation energy absorbed by the sun, the outer wall surface of the refrigerator is usually painted white or light color. Therefore, the installation of cold storage is different from the general industrial and civil installation.
冷库安装要防止水蒸气的扩散和空气的渗透。室外空气侵入时不但增加冷库的耗冷量,而且还向库房内带入水分,水分的凝结引起安装结构特别是隔热结构受潮冻结损坏,所以要设置防潮隔热层,使冷库建筑具有良好的密封性和防潮隔汽性能。
Cold storage installation to prevent the proliferation of water vapor and air infiltration. The outdoor air intrusion will not only increase the consumption of cold storage, but also to the warehouse into the water, the water condensation caused by installation structure especially the insulation moisture freeze damage, so to set up the thermal insulation layer, the cold storage building has good sealing and moisture vapor barrier properties.
冷库的地基受低温的影响,土壤中的水分易被冻结。因土壤冻结后体积膨胀,会引起地面破裂及整个安装结构变形,严重的会使冷库不能使用。为此,低温冷库地坪除要有有效的隔热层外,隔热层下还必须进行处理,以防止土壤冻结。
The foundation of cold storage is affected by low temperature. Because of the volume expansion of the soil after freezing, it will cause the ground rupture and the whole installation structure deformation. To this end, in addition to the low-temperature cold storage floor to have an effective insulation layer, the insulation layer must also be processed to prevent soil freezing.
冷库的楼板要堆放大量的货物,又要通行各种装卸运输机械设备,平顶上还设有制冷设备或管道。因此,它的结构应坚固并具有较大的承载力。
The floor of the cold storage to pile up a large number of goods, but also through a variety of loading and unloading transport machinery and equipment, flat top is also equipped with refrigeration equipment or pipes. Therefore, its structure should be strong and have a large bearing capacity.
低温环境中,特别是在周期性冻结和融解循环过程中,建筑结构易受破坏。因此,冷库的建筑材料和冷库的各部分构造要有足够的抗冻性能。
In low temperature environment, especially in the period of freezing and thawing cycle in the process of building structure, easy to be damaged. Therefore, the cold storage of building materials and cold storage of the various parts of the structure should have sufficient frost resistance.
总的来说,冷库建筑是以其严格的隔热性、密封性、坚固性和抗冻性来保证建筑物的质量。
Generally speaking, the cold storage building is to ensure the quality of the building with its strict insulation, sealing, firmness and frost resistance.
