The first step of cold storage construction: the choice of cold storage address.
Cold storage can be divided into three categories: storage cold storage, retail cold storage, and production cold storage. The production cold storage is built in the production area with more concentrated supply, according to the nature of use. Factors such as convenient transportation and market connections should also be considered. The cold storage is better to be built in a shady place without sunlight and frequent hot wind, and the small cold storage is built indoors. There should be good drainage conditions around the cold storage, and the groundwater level should be low. In addition, before the construction of the cold storage, the three-phase power supply of the corresponding capacity should be set up in advance according to the power of the refrigerator. If the cold storage is water-cooled, the water pipes should be laid and the cooling tower should be built.
The second step of cold storage construction: determination of cold storage capacity.
In addition to the aisles between the rows, the size of the cold storage should be designed according to the maximum amount of agricultural products to be stored throughout the year. This capacity is based on the volume that must be occupied by the stored product to be stacked in the cold room. Spaces between stacks and walls, ceilings, and gaps between packs, etc. are calculated. After determining the capacity of the cold storage, determine the length and height of the cold storage. Necessary ancillary buildings and facilities, such as workshops, packaging and finishing rooms, tool warehouses and loading and unloading platforms, should also be considered when the cold storage is constructed.
The third step of cold storage construction: selection and installation of cold storage insulation materials.
In order to have good thermal insulation performance, the selection of cold storage insulation materials must be adapted to local conditions. And economical. There are several types of cold storage insulation materials. One is a plate processed into a fixed shape and specification, with a fixed length, width and thickness. The corresponding specifications of the storage board can be selected according to the needs of the storage body installation. 10 cm thick storage board, 15 cm thick storage board is generally used for low temperature cold storage and freezing cold storage; another type of cold storage can be foamed with polyurethane spray, and the material can be sprayed directly into the brick or concrete warehouse of the cold storage to be built, and the shape is set. The rear is both moisture-proof and heat-insulating. The structure of modern cold storage is developing towards prefabricated cold storage. Cold storage components including moisture-proof layer and thermal insulation layer are made and assembled on site. The advantages are that the construction is convenient, fast, and movable, but the cost is relatively high.
The fourth step in the construction of the cold storage: the selection of the cooling system of the cold storage.
Small refrigerators mainly use fully enclosed compressors, which are relatively cheap because of the low power of fully enclosed compressors. The choice of cold storage cooling system is mainly the selection of cold storage compressor and evaporator. Medium-sized refrigerators generally use semi-hermetic compressors; large refrigerators use semi-hermetic compressors.
