CastellionInstallation and design of cold storageWhat are the parameters of elasticity

The average service life of rigid polyurethane insulation structure with stable quality, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Castellion,The shelves in the warehouse shall have sufficient strength and rigidity.With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore some small problems may be ignored during installation. According to the following understanding.Samragd ,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, the image of frosting may appear after use for a period of time. If we do not defrost in time, it will also affect the effect of. Therefore, I hope you must pay attention to defrosting.Moreover, polyurethane does not produce harmful gas at high temperature.The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.

No matter whether the food cold storage or quick-frozen storage is in use, fixed length,CastellionCold storage installation, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use cm thick refrigerator plates, and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use cm or cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance, but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable, but the project cost is relatively high.Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc.Installation material list,The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic,CastellionPharmaceutical cold storage installation company, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room sorting room, quick freezing room, refrigeration room, unloading platform, etc.

On the basis of cold storage and preservation, the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?details,When the cold storage is used for the first time or shut down for a long time it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.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 defrost in time. Pay attention to the maintenance of the evaporator of the controlled atmosphere storage system. If the evaporator frosts, 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, and has little impact on the storage temperatureKg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Castellion,Danfoss thermal valve is adopted for the thermal valve of the cold storage, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range it will automatically alarm, which is of great significance to the proper preservation of the cold storage.When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, liquid inlet hole, return hole,CastellionCold storage factory installation, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of mm and mm outside.Features of quick freezing warehouse: the quick freezing technology is advanced, 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.
