In the construction process of cold storage, the selection of insulation materials is crucial. It is not only related to the safety of cold storage, but also directly affects the energy consumption and operating costs of cold storage. This article will introduce in detail the selection criteria of cold storage exterior wall insulation materials, as well as the performance and applicability of various insulation materials.

1. Types and performance of insulation materials

1. Polystyrene foam: This is a commonly used insulation material with good insulation performance and durability. Its unique closed-cell structure gives it good thermal insulation performance, while being light and easy to install. However, it should be noted that polystyrene foam is flammable, and products with higher flame retardant or fireproof grades need to be selected.

2. Rock wool: Rock wool is a mineral wool product with good thermal insulation performance and good durability. It has low thermal conductivity and good sound insulation and fireproof performance. However, rock wool is not good for the skin, and protective measures need to be taken.

3. Vacuum insulation board (VIP): VIP is a new type of insulation material that prevents heat conduction by placing various insulation materials in a high vacuum environment. VIP has excellent thermal insulation performance and durability, and is easy to install. However, the price of VIP is relatively high, and it needs to be selected according to the budget.

2. Selection of cold storage exterior wall insulation materials

The selection of cold storage exterior wall insulation materials should comprehensively consider factors such as its thermal insulation performance, weather resistance, fire resistance, environmental protection performance, and installation convenience. Generally speaking, polystyrene foam and vacuum insulation panels (VIP) are more ideal choices.

For small cold storage or newly built cold storage, it is recommended to use polystyrene foam as the exterior wall insulation material. Its thermal insulation performance and durability can ensure the safety and operation of the cold storage. At the same time, due to its light weight, it is easy to install and convenient for construction.

For large cold storage or cold storage that requires long-term stable operation, vacuum insulation panels (VIP) are a good choice. Its excellent thermal insulation performance and durability can meet the needs of large cold storage, and its installation is simple and does not require a lot of manpower and material resources.

In addition, for cold storage in certain specific environments, such as chemical, pharmaceutical and other places with high environmental requirements, insulation materials with excellent environmental performance, such as rock wool, should be selected. However, when using these materials, it is necessary to pay attention to the possible harm to the skin and take appropriate protective measures.

3. Case analysis

Take the newly built cold storage of a large refrigerated logistics company as an example. The cold storage is located in the urban area and has high requirements for environmental protection and fire prevention. Therefore, after comprehensive consideration, vacuum insulation panels (VIP) were selected as the exterior wall insulation material. After the construction was completed, the cold storage showed excellent insulation performance and stability, reduced energy consumption and improved operational efficiency.

Conclusion:

The selection of insulation materials for the exterior wall of the cold storage is one of the key factors to ensure the safety and operation of the cold storage. When selecting insulation materials, factors such as insulation performance, weather resistance, fire resistance, environmental protection performance and installation convenience should be comprehensively considered. According to different use environments and needs, choosing suitable insulation materials can ensure the safety and stable operation of the cold storage.
