(Summary description)Cold storage refers to constant temperature storage air-conditioning equipment for food, dairy products, meat, aquatic products, chemicals, medicine, seedlings, scientific experiments, etc. In fact, the cold storage is very similar to the refrigerator, but the area of the cold storage is much larger than that of the refrigerator, and the temperature range is wider than that of the refrigerator. The ultra-low temperature freezing of the cold storage is not reachable by the refrigerator, but they have the same refrigeration principle. The following Lengdi Refrigeration will explain to you the precautions for using the cold storage! (1) Under normal circumstances, it is not recommended to manually control the temperature of the refrigeration switch to ensure the appropriate temperature for automatic operation; (2) Regularly check the operation control and temperature changes of the unit by the control cabinet,

Information
Cold storage refers to constant temperature storage air-conditioning equipment for food, dairy products, meat, aquatic products, chemicals, medicine, seedlings, scientific experiments, etc. In fact, the cold storage is very similar to the refrigerator, but the area of the cold storage is much larger than that of the refrigerator, and the temperature range is wider than that of the refrigerator. The ultra-low temperature freezing of the cold storage is not reachable by the refrigerator, but they have the same refrigeration principle. The following Lengdi Refrigeration will explain to you the precautions for using the cold storage!
 
       (1) Under normal circumstances, it is not recommended to manually operate the freezing switch to control the temperature to ensure a suitable temperature for automatic operation;
       (2) Regularly check the operation control and temperature changes of the unit by the control cabinet. If the temperature does not drop for a long time, it should be shut down for inspection;
       (3) Regularly check whether the power supply voltage is normal;
       (4) Strictly control the amount of storage to ensure that the air-conditioning cycle is unblocked, and do not block the air outlet and return air duct of the air cooler when the goods are stacked;
       (5) Regularly ventilate the warehouse, defrost regularly, and do not use sharper equipment for defrosting to avoid damage to the evaporator;
       (6) To prevent the electrical parts and control cabinets in the cold storage from contacting rainwater and causing equipment damage and safety accidents, outdoor cold storage must be equipped with rainproof sheds to prevent rainwater from corroding the storage board;
       (7) If there are frequent power outages at the construction site of the cold storage, emergency power supply should also be equipped to avoid the deterioration of the food in the cold storage and reduce the food profit;
       (8) Do not modify the control route without authorization;
       (9) Do not run and frequently start the compressor under over-working conditions.

What problems should be paid attention to when transforming a warehouse into a cold storage

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.

The importance of cold storage design

Usually, customers will ask the cold storage engineering company to produce a detailed cold storage design plan in the initial stage of consulting the construction of the cold storage. Especially for large-scale cold storage, the design plan is the most important part of the entire cold storage construction process. Today, I will introduce to you the importance of cold storage design.
