What are the hazards of water leakage in a cold storage?

Cold storage is different from general industrial and civil buildings. It is a low-temperature sealed storage built with thermal insulation materials. Its cold storage structure is relatively complex and has a high cost. It is afraid of moisture, water, hot air, and cold leakage. It is most taboo to have ice, frost, water, and steam. Once the civil engineering of cold storage, such as insulation and other structures, seeps water, it will cause a series of problems.
If the water seepage of the cold storage penetrates the wall or the moisture-proof and vapor barrier layer and insulation layer, then when the temperature of the cold storage is below 0°C, the water will freeze. Due to the increase in volume when water freezes, it will squeeze the insulation layer and cause deformation. The temperature of the cold storage will fluctuate. When the temperature of the cold storage rises, the ice formed by the seepage water at low temperatures will slowly melt and at the same time will absorb the water on the outside. When the temperature of the cold storage drops again, the water freezes again.

Such repeated cycles of freezing and melting. Since moisture on the outside will be absorbed every time the ice melts, and the volume of ice formed each time will be larger than the previous ice. Naturally, the squeezing of the insulation board will increase each time. Eventually, cracks will appear in the insulation layer and the wall.

If it is not rescued all the time, the cracks will naturally become wider and wider. The insulation layer of the cold storage begins to penetrate, and the cold air in the cold storage leaks out, naturally having a great impact on the preservation effect of the cold storage.
During the operation of the cold storage, the cold storage should be maintained well. Regularly check whether there is water leakage on the cold storage surface, whether the cold storage drainage is smooth, whether the downspout is damaged, and whether there is water seepage in the external drainage pipeline of the cold storage. If there is any, it must be repaired in time and protective measures must be taken.
While maintaining and inspecting the cold storage, also observe whether the ground of the cold storage is normal, whether there is bulging, whether the insulation layer has dropped, become damp, or whether there are cracks. If these phenomena occur, be sure to find the cause and take remedial measures to prevent it from becoming serious.
