If the moisture-proof gas insulation layer of the cold room insulation structure is not properly handled, the water vapor in the outside air will constantly invade the storage, bringing different degrees of harm to the cold room:
1. Reduce the thermal insulation performance of cold room
2. Affect the stability of the temperature in the library, the temperature in the library rises, so that the running time of refrigeration equipment is longer, and the energy consumption is increased.
3. Because the temperature inside and outside the cold room is different, accompanied by heat transfer, there will be water vapor penetration.
4. Corrosion insulation materials, resulting in cold room plate mildew and other problems to lose insulation function.
Therefore, it is of great significance to do a good job in maintaining the moisture-proof air insulation layer of cold room to improve efficiency and energy saving.
