Analysis of the reason why cold storage should not be built underground

Analysis of the reason why cold storage should not be built underground Many people think that building cold storage underground will have better thermal insulation effect than cold storage on the ground, because in the past, when the technology was backward, it was very common to choose cellars as crop storage. But from a commercial point of view, it is not scientific to blindly build the cold storage underground. The cold storage construction team stands from the perspective of consideration for customers. Generally, it is not recommended to make the cold storage underground. Because the temperature of the exterior wall of the normally designed cold storage is basically the same as the outside temperature, there is no need to build the cold storage underground, and if it is built underground, the humidity will have a great impact on the cold storage, and pay attention to the cold storage Moisture-proof and waterproof, excavation also requires a lot of money, which is easy to cause a lot of unnecessary waste of manpower, material resources, and financial resources for customers! From a commercial point of view, the cold storage should be built in a place with convenient transportation and reliable sources of water and electricity supply. There should be good environmental sanitation conditions around the site, as far as possible to avoid harmful gases, smoke, dust and pollution sources from industrial and mining enterprises. The The flat layout of the cold storage should make the process flow reasonable, the route short, not cross, the high and low temperature zones are clear, try to reduce the area of ​​the enclosure structure, the column network is neatly distributed, and consider the convenience of expansion and maintenance. The single-story floor is separated from the ground by thermal insulation walls between the high and low temperature warehouses. The warehouse door is connected to the room temperature through the hall. An air curtain is installed on the warehouse door to prevent the cold air in the warehouse from overflowing. The walls, ceilings, and floors of the cold storage should be laid with materials with low thermal conductivity, such as asphalt, expanded perlite blocks, etc., as the heat insulation layer. At present, the most commonly used is moisture-proof extruded plastic board or polyurethane spraying to prevent the external heat flow from entering the storage Inside, increase the heat load. At the same time, in order to prevent outdoor water vapor from infiltrating into the insulation layer, it is necessary to lay a material with a large penetration resistance on the high temperature side of the insulation layer, such as asphalt linoleum, etc., as a gas barrier layer. At present, polymer moisture-proof materials are generally used. In summary, it is very unreasonable to select the location of the cold storage construction underground. The reasonable location of the cold storage needs to be determined according to the characteristics of the use of the cold storage and other aspects.
