The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.Witten,What are the common sense of protection and maintenance of fresh-keeping warehouse equipment? Nowadays, the application scope of fresh-keeping storehouse is more and more extensive. It is closely related to our daily life. In addition to food production factories, stores and restaurants have begun to build fresh-keeping storehouses. The main purpose of building a fresh-keeping warehouse is to ensure the freshness of food. There are many precautions in the process of fresh-keeping warehouse. After completion, there are also many protection and maintenance items. Regular maintenance and protection of fresh-keeping warehouse can increase its service life. Therefore, it is necessary for operators to understand some common knowledge about the protection and maintenance of fresh-keeping warehouse equipment. What are the common knowledge about the protection and maintenance of fresh-keeping warehouse equipment?Compression refrigerator is commonly used. It is mainly composed of compressor, condenser, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.Zuenoula, - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance,WittenUndertake cold storage installation, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operation

During the installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation find out the problems that are easy to be ignored, which will affect the use of the cold storage or the whole installation process and avoid the wrong installation, so as to waste resources and increase the cost.The air conditioning warehouse is equipped with standby power supply. After eliminating the line and load problems, it is the maintenance of external irresistible power lines. If the refrigerated goods in the air conditioning warehouse are expensive or vulnerable to temperature changes, it can be considered to equip the air conditioning warehouse with standby power supply to ensure the operation of refrigeration equipment in the cold storage in a short time after power failure. Large air conditioning warehouses can be considered to be equipped with generator sets, Automatically switch the generator set for power generation after power failure for use. For example, dual mains power can be used.Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.Industry management,Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic with small density, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, it is the selection of raw materials, such as refrigeration compressors, refrigeration units, thermal insulation materials, doors, temperatures and other refrigeration equipment.

The average service life of rigid polyurethane insulation structure with stable quality,WittenInstallation price of cold storage, it will not be affected by drying, or electrochemical corrosion,WittenInstallation of fresh storage, as well as the growth of insects, fungi or algae or rodents.knowledgeEmergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.If the controlled atmosphere storage is not used for a long time, does it also require refrigeration? If the controlled atmosphere storage is not used for a long time after installation, it does not need refrigeration operation as long as it does not show fluorine leakage. However, there may be fluorine leakage due to long-term non use, so refrigeration operation should be carried out at this time. - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.Witten,According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the st century.The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.
