Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.BassettWhen the valve is opened too large or too small, the fresh-keeping warehouse will lead to too large or too small refrigerant flow, poor valve operation, reduced refrigeration efficiency and even equipment damage.In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.Danghara,The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage,BassettSeed preservation cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, type and budget of the cold storage.

The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.Hot gas defrosting, the heat released when the superheated steam of the compressor condenses to melt the double layers on the surface of the evaporator. It is characterized by strong applicability and reasonable energy. For the ammonia refrigeration system, the oil accumulated in the evaporator can be washed out while defrosting, but the defrosting time is long, which has a certain impact on the storage temperature, and the sub regulation station of the refrigeration system is complex.During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.Direct material,Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.

These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.Customer first,The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.Frosting of evaporator will increase thermal resistance and decrease heat transfer coefficient. For the cooling fan, the air circulation cross-sectional area is reduced, the circulation resistance is increased, and the power consumption is increased. Therefore, it will affect the normal use of the controlled atmosphere storage. How to defrost in time? The current scheme of the controlled atmosphere storage includes: manual defrosting, which is simple and easy,BassettFresh storage installation Telephone, and has little impact on the storage temperatureConnect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.Bassett,After being stored in the medical cold storage project, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use, so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, the image of frosting may appear after use for a period of time. If we do not defrost in time,BassettWhich is a good medicine cold storage, I hope you must pay attention to defrosting.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.The drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.
