Refrigerated storage rooms are mainly used for short-term or long-term preservation and storage of fruits, vegetables, dairy products, eggs, tea, red wine and other foods. The temperature requirement for the storage room is relatively stable, otherwise it will affect the quality of the food. Refrigerated storage is widely used in various industries such as food, supermarkets, meat, dairy, seafood, fruits and vegetables, pharmaceuticals, etc. The temperature inside the refrigerated and fresh-keeping warehouse is generally around 0-15 ℃,To obtain the quotation for refrigerated storage, please call the customer service hotline of Yinxue Refrigeration.

　　Cost Explanation for Refrigerated and Freshly Preserved Cold Storage

The cost of refrigeration and preservation cold storage is related to various factors such as the selection of refrigeration equipment and accessories, the material, specifications, and quantity of cold storage panels and doors, manual installation, and logistics transportation. The cost cannot be calculated using the method of how much it costs per square meter (cubic meter), which is a misconception. In general, the larger the capacity of a refrigerated storage, the lower the cost per square meter (cubic meter). Here are some reference costs for common capacity sizes of refrigerated and fresh-keeping cold storage:

　　The cost of 10-20 cubic meters is 15000 to 20000 yuan, 30-50 cubic meters is 20000 to 28000 yuan, 60-100 cubic meters is 30000 to 40000 yuan, 100-200 cubic meters is 40000 to 60000 yuan, 200-300 cubic meters is 50000 to 80000 yuan, 400-600 cubic meters is 80000 to 140000 yuan, 1000 cubic meters is 150000 to 200000 yuan, and 3000 cubic meters is 350000 to 450000 yuan.

　　Construction requirements for refrigerated and fresh-keeping cold storage

1. Insulation and cooling. Appropriate insulation layers should be installed to block the intrusion of external heat, and the outer surface of the cold storage should be painted white or light to reduce solar radiation.

2. Moisture and vapor barrier. Install a layer of vapor barrier or waterproof and moisture-proof layer on the side of the insulation layer to prevent water vapor from entering the vapor barrier and reducing the insulation performance.

3. Install insulation layers or anti freezing heating measures on the ground to prevent soil freezing and damage to the cold storage structure.

4. Reasonable zoning of cold and hot storage reduces frequent freeze-thaw cycles and minimizes the possibility of damaging the structure of the cold storage.

　　Maintenance and upkeep of refrigerated and fresh storage facilities

1. The oil level of the oil mirror of the refrigeration compressor in the cold storage should be within the specified range to prevent compressor failure due to lack of oil.

2. Before using the refrigeration unit of the cold storage, it is necessary to check whether the power supply and ambient temperature are within the specified range.

3. To maintain a dry environment around the refrigeration unit of the cold storage, it is necessary to prevent water and impurities from leaving on the steel pipes, and to prevent rusting. At the same time, the refrigeration unit should be equipped with a current protection device to prevent the machine from operating under overload.
