介紹冷庫制冷管道和冷庫設備的隔熱
Introduces the heat insulation of cold storage refrigeration pipe and cold storage equipment
冷庫制冷系統隔熱的目的，是為了減少冷庫設備和管道內的制冷劑及載冷劑從環境介質吸熱，降低由于內外溫差所引起的冷量損耗；食品冷庫
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;
防止冷庫設備和管道外表面結露、結霜；改善勞動條件和工作環境，保證人工制冷的效果等，熱氨沖霜管道的隔熱則是為了減少制冷劑蒸氣的熱量損失、縮短沖霜時間、提高沖霜效果。
To prevent the cold storage equipment and pipe surface condensation, frost; Improve working conditions and working environment, guarantee the effect of artificial refrigeration, such as 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.
冷庫制冷管道和冷庫設備的隔熱材料有軟木、聚苯乙烯泡沫塑料、玻璃棉、聚氨酯等。為了施工方便，一般先加工成板材、管殼和管件，施工時可以直接割、鋸加工包扎冷庫設備和管道，并用粘接劑粘貼。
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.
但這種采用拼裝的隔熱層，若隔氣處理不好，會使隔熱層受潮，性能降低。采用聚氨酯現場發泡，可以解決這個問題，尤其對于結構形狀較復雜的部位效果更好。
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.
由于聚氨酯發泡反應時能與被隔熱表面自行粘合，整體性好、沒有接縫，而且一次成型隔熱效果顯著，所以更有利于節能和后期維護。
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.
