Why should we install moisture-proof gas barriers in cold storage cost engineering?

What is the role of moisture-proof gas barriers in cold storage cost engineering? It’s not everyone knows, and some friends think that it’s okay to use and not to use. It’s not a cost. It’s not as simple as you think. It’s a major cooling effect for the cold storage cost project. Impact.

Due to the large temperature difference between the inner and outer air, the cold storage cost project will inevitably form a water vapor pressure difference corresponding to the temperature difference, and then the water vapor will penetrate from the high temperature side with higher partial pressure through the maintenance structure to the cold storage cost engineering with lower partial pressure. . When the water vapor passes through the inside of the enclosure and reaches a temperature zone below the dew point of the air, the water vapor condenses into water or freezes, causing damage to the insulation structure.

The presence or absence of air and moisture in cold storage cost engineering plays a decisive role in the thermal insulation performance of the envelope structure, and the moisture barrier layer is unreasonably set, which will also cause serious damage to the enclosure. If the vapor-proof moisture-proof layer is not properly handled, it is difficult to obtain good heat insulation effect regardless of the material and thickness of the insulation layer of the cold storage cost engineering.

Therefore, the moisture-proof gas barrier layer plays an important role in the cold storage cost engineering. The thinner insulation layer can also be compensated by increasing the capacity of the cold storage cost engineering refrigeration unit. If the moisture barrier layer is poorly designed and constructed, the outside world The water vapor in the air continuously intrudes into the insulation layer and into the cold storage, and produces the following results:

1. causing decay and disintegration of the insulating material;

2. causing corrosion of building materials;

3. Increase the frost on the surface of the evaporator in the cold storage cost project, increase the number of defrost, affect the temperature of the cold storage and the quality of the stored goods;

4. Accelerate the temperature rise of the cold storage cost project and increase the power consumption and cooling cost;

5. The long-term penetration of water vapor will result in the destruction of the maintenance structure, and even the entire cold storage building will be scrapped.

Therefore, in the design and construction of the cold storage cost engineering, sufficient attention should be paid to the maintenance of the structure of the steam-proof and moisture-proof, so friends must be careful and pay attention when installing the moisture-proof gas barrier in the future, otherwise it will affect the use of the cold storage, and Preservation of items in the cold storage.
