為什么冷庫庫溫下降慢：
Why cold storage is slowing down:
1、蒸發器表面結霜太厚或積塵過多，傳熱效果下降。
1, the surface of evaporator is too thick or too dusty, the heat transfer effect decreases.
導致冷庫溫度下降緩慢的另一重要原因是蒸發器傳熱效率低，這主要是由于蒸發器表面霜層過厚或積塵過多引起的。由于冷庫蒸發器的表面溫度大多低于0℃，而庫房濕度相對較高，空氣中的水分極易在蒸發器表面結霜，甚至結冰，影響蒸發器的傳熱效果。為防止蒸發器的表面霜層過厚，需定期對其進行除霜。
Another important reason for the slow led to the decrease of the cold storage temperature evaporator heat transfer efficiency is low, this is mainly due to the too thickness of evaporator surface frost layer or dust caused by too much. Because of the cold storage most of the surface temperature of the evaporator is lower than 0 ℃, relative humidity and warehouse is higher, the moisture in the air extremely easy in the evaporator surface frost, ice, even influence the effect of heat transfer in the evaporator. In order to prevent the surface frost layer of evaporator from overthick, it needs to be defrosted on a regular basis.
2、冷庫由于隔熱或密封性能差，導致冷量損耗大。
Cold storage is caused by poor insulation or poor seal performance.
隔熱性能差是由于管道、庫房隔熱墻等的保溫層厚度不夠，隔熱和保溫效果不良，它主要是設計時保溫層厚度選擇不當或施工時保溫材料質量差所導致的。另外，在施工使用過程中，保溫材料的保溫防潮性能有可能被破壞導致保溫層受潮、變形，甚至糜爛，其隔熱保溫能力下降，庫防冷量損耗隨之增大，庫溫下降明顯減緩。
Poor heat insulation performance is due to pipe, such as the warehouse heat insulation wall insulation layer thickness is not enough, heat insulation and heat preservation effect is bad, it is mainly the design when choosing improper or construction of insulation layer thickness of heat preservation material as a result of poor quality. In addition, in the construction, in use process of insulation materials insulation moistureproof performance is likely to be damage to insulation layer be affected with damp be affected with damp, deformation, erosion, and even the loss of heat insulation, library cold energy loss increase, library temperature slowed down significantly.
導致冷損耗大的另一重要原因是庫房密封性能差，有較多的熱空氣從漏氣處侵入庫房。一般若在庫房門的密封條或冷庫隔熱壁密封處出現了結露現象，則說明該處密封不嚴密。
Another important reason for the high cooling loss is the poor sealing performance of the warehouse, which has more hot air to enter the storage room from the leakage. It is indicated that the sealing of the seal in the sealing bar of the warehouse door or the insulation wall of the freezer is not tight.
另外，頻繁開關庫房門或較多的人一起進入庫房，也會加大庫房冷量損耗。應盡量避免打開庫門，防止大量熱空氣進入庫房。當然，庫房進存貨頻繁或進貨量太大時，熱負荷急劇增大，要降溫至規定溫度一般需要較長時間。
In addition, frequent switch storehouse door or more person enter the warehouse, also can increase the store cold quantity loss. Try to avoid opening the library door and prevent a lot of hot air from entering the warehouse. Of course, when the warehouse enters the inventory frequently or the quantity is too big, the heat load increases sharply, to cool to the regulation temperature normally takes a long time.
