If the moisture-proof air isolation layer of the cold storage insulation structure is not handled properly, the water vapor in the outside air will constantly invade the storage, bringing different degrees of harm to the cold storage:
1. It will reduce the thermal insulation performance of cold storage.
2. It will affect the stability of temperature in the library, the temperature in the library rises, which lengthens the operation time of refrigeration equipment and increases the energy consumption.
3. Because the temperature inside and outside the cold storage is different, with the transfer of heat, there will be water vapor penetration.
4. Corrosion of insulation materials, resulting in cold storage board mildew and other problems to lose the insulation function.
Therefore, it is of great significance to improve efficiency and save energy to do a good job in the maintenance of moisture-proof air insulation layer of cold storage.
