Matters needing attention in improving the quality of cold storage installation

In fact, different construction methods and installation materials are the key to directly affecting the smooth progress of the cold storage installation project. Therefore, every cold storage installer must pay more attention and attention to effectively ensure the smoothness of the cold storage in the later application. Let's take a look together.

1. The traditional cold storage installation design is generally about 5m high, but in practical applications, especially the installation utilization rate of the cold storage without shelf layer is less than 50%. For example, once the stacking height of items reaches 3.2m, the outer packaging is Food in cartons are prone to packaging cracks and collapses due to heavy pressure, deformation, moisture absorption, etc., which leads to reduced food quality and greater economic losses.

　　2. Selection of cooling method. At present, most of the combined warehouses newly built in China or imported from abroad use forced circulation. However, considering the impact on the goods, the cooling methods of warehouses generally include natural convection cooling and forced circulation. Natural convection methods are mostly used in countries. At this stage, it is more reasonable to adopt a conservative natural convection method. One is because the quality of goods stored in domestic cold storage is poor, and naked goods account for a large proportion. If forced circulation cooling is used, the dry consumption of goods is heavier. Second, the natural convection cooling mostly adopts the smashing tube type. This method has a large amount of liquid storage and a strong storage capacity, which can prevent frequent start-ups and can make better use of China’s cold storage installation policies. Turn on when the price is low, saving electricity expenses.

　　 3. Part of the cold storage installation design is not standardized and there is a safety hazard. Many domestic cold storages are designed and installed without a license, lacking uniform standards, and lack of special equipment safety technical files are more common. Operators have no professional training without a certificate, and management personnel have a weak safety awareness. Some civil food cold storages with a volume of more than 500m3 using ammonia as the refrigerant seriously fail to meet the requirements of the "Code for Design of Cold Storage Installations" (GB50072-2001) in terms of location selection, foundation treatment, and installation of refrigeration equipment, and there are many potential safety hazards. Many cold storages are called controlled atmosphere storages, but they fail to achieve the purpose of controlled atmospheres. Some low-temperature storages face the situation of being out of service or can only be used as high-temperature storages when they are completed.

As long as you strictly abide by the cold storage installation process, you can effectively improve the smooth operability of the cold storage. Therefore, for the relevant introductions and points given to everyone above, I hope that it can attract the attention and attention of every operator, so as to more effectively guarantee the cold storage. Smoothness in the late application period.
