Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.
Danfoss thermal valve is adopted for the thermal valve of the cold storage，DILBECKCold storage transfer， with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature，DILBECKLarge cold storage engineering installation company， 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.
DILBECKAn air duct is generally set in the vegetable cold storage. The air flow from the upper air duct mouth blows to the wall and the lower product line， returns to the middle， is absorbed by the lower part of the evaporator， and the evaporator drains and returns to the air duct again.
Generally speaking， the construction of cold storage is to ensure the quality of buildings with its strict heat insulation， sealing， firmness and frost resistance.
BitolaVent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall， a closed platform， an electric sliding refrigerated door， an anti-collision flexible seal and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
Reasonable space: the power consumption of the cold storage is calculated according to the cold consumption of the cold storage， which usually includes two parts: the cold consumption during cargo cooling and refrigeration; It is the cooling consumption of the refrigeration room itself and operation management.
The selection of equipment for the construction of equipment cold storage is closely related to the size， type and budget of the cold storage.
Selection of refrigeration unit in cold storage: the selection of cold storage system software is mainly the use of refrigeration compressor and air conditioning evaporator in cold storage.
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.
projectRefrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy， environmental protection and performance of cold storage.
The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material， storage and circulation effect and reduces operation energy consumption. Of course， more important is the choice of refrigeration system. For example， at present， the refrigeration system of fluorine refrigerant is still the mainstream but when selecting the type and power of cooling equipment， it is necessary to calculate the data for the installation of cold storage， and then make a high-quality choice.
The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
With the rapid development of modern commerce， the original cold storage for the purpose of product storage can no longer meet the rapid， accurate and small batch circulation needs of modern commodities. Therefore， the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly， so as to avoid the problem of purchase errors. In the process of handling， it is also necessary to strictly follow the instructions.
After the welding of the whole system， the air tightness test shall be carried out， and the high-pressure end shall be filled with mp nitrogen. Nitrogen charging MP at low pressure end. During pressurization， conduct leak detection with soapy water， and carefully inspect all welded junctions， so as to keep the pressure from falling off after the completion of simplicity.
Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality， timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally， the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.
DILBECKThe service life of the cold storage depends on the quality of the refrigeration equipment， but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times， people often ignore the latter point. In daily life， as long as we maintain and maintain the cold storage regularly we can greatly improve the service life of the cold storage and reduce the cost.
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， 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， the temperature of the warehouse will drop slowly.
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 and have strict requirements for temperature and humidity.
