冷库制冷管道和冷库设备的隔热
Cold storage refrigeration pipe insulation and cold storage equipment
冷库制冷管道和冷库设备的隔热材料有软木、聚苯乙烯泡沫塑料、玻璃棉、聚氨酯等。为了施工方便，一般先加工成板材、管壳和管件，施工时可以直接割、锯加工包扎冷库设备和管道，并用粘接剂粘贴。

Cold storage refrigeration pipe and cold storage equipment of the insulation material with cork, polystyrene foam plastic, glass cotton, polyurethane, etc. To construction is convenient, the first processed into sheets, shell and tube, the construction can be directly cut, saw processing bandage cold storage equipment and pipeline, and adhesive paste.
但这种采用拼装的隔热层，若隔气处理不好，会使隔热层受潮，性能降低。采用聚氨酯现场发泡，可以解决这个问题，尤其对于结构形状较复杂的部位效果更好。
But if this using assemble insulating layer, the gas treatment is bad, can make the heat insulation layer of be affected with damp be affected with damp, performance degradation. Using polyurethane foamed, can solve this problem, especially for better structure more complex shape parts.
由于聚氨酯发泡反应时能与被隔热表面自行粘合，整体性好、没有接缝，而且一次成型隔热效果显著，所以更有利于节能和后期维护。
Because of polyurethane foam reaction can be heat insulation and surface adhesion, integral sex is good, no seams, and a molding heat insulation effect significantly, so more conducive to energy conservation and the maintenance of late.
冷库制冷系统隔热的目的，是为了减少冷库设备和管道内的制冷剂及载冷剂从环境介质吸热，降低由于内外温差所引起的冷量损耗；
Cold storage refrigeration system, the purpose of insulation is to reduce the amount of refrigerant and cold storage equipment and pipe load cooling medium heat from the environment, reduce the loss of the cold caused by temperature difference between inside and outside;
防止冷库设备和管道外表面结露、结霜；改善劳动条件和工作环境，保证人工制冷的效果等。热氨冲霜管道的隔热则是为了减少制冷剂蒸气的热量损失、缩短冲霜时间、提高冲霜效果。
To prevent the cold storage equipment and pipe surface condensation, frost; Improve the working conditions and working environment, guarantee the effect of artificial refrigeration, etc. Thermal insulation pipe of hot ammonia gas defrosting is to reduce the number of refrigerant vapor heat loss, reducing gas defrosting time, improve the effect of gas defrosting.
