(Summary description)In order to store fruits for a long time, many vendors have transformed their original warehouses into fruit fresh-keeping cold storages. However, there are still big differences between warehouses and cold storages. So what issues should be paid attention to when transforming warehouses into cold storages! 1. It is necessary to consider whether the thermal insulation structure of the original warehouse is suitable for cold storage and preservation. Generally, the exterior of the warehouse is made of polystyrene double-layer color steel plates or rock wool boards. This type of structure is not suitable for refrigeration, preservation, and quick-freezing. It is only suitable for storage at 15°C. If it is lower than 15°C ℃, it is recommended to add polyurethane double-sided color steel warehouse board of corresponding thickness in the warehouse. Generally, this kind of warehouse board has good heat preservation effect and high fire resistance level. 2. The bearing capacity of the steel structure at the top of the original warehouse needs to be considered. Some warehouse roofs use arc-shaped round pipe structures, which have limited force and cannot withstand large-area cold storage roofs. This is also the need to pay attention to the transformation. 3. Some warehouses are simple cement floors and are not suitable for reconstruction and construction of cold storage. Therefore, ground insulation treatment needs to be considered. If the temperature is below 0℃, the ventilation pipe must be pre-embedded to prevent the foundation from sinking due to the low temperature. In this way, the bottom material should be extruded board, air- and moisture-proof layer, concrete layer, etc., in short, moisture, water and heat preservation should be done. 4. Consider the carrying capacity of power equipment. Since it used to be an ordinary warehouse, the original power may not take into account the use of later equipment, so we also need to pay attention to power cables. Electricity for cold storage generally requires 380V commercial electricity. Maungsheng Refrigeration does not recommend using 220V for cold storage construction, even small fresh-keeping cold storage is not recommended. The specific cold storage construction uses 200V electricity or 380V electricity can see detailed analysis. 5. It is necessary to consider whether the warehouse can penetrate the wall hole, because the cold storage needs to be connected with the internal unit during installation to ensure its freezing effect. 6. The design of cold storage shelves also needs to consider other factors, such as: the selection of welding electrodes in the cold storage should correspond to the material and welding process requirements of the welding base material and ensure the welding quality of the welds. The characteristics of frosting in the cold storage should be considered, the weight gain should be appropriately considered when calculating the shelf selection, and the customer's refrigeration and defrosting process should be considered for the corrosion resistance of the structural spray coating.
