NubarisInstallation of second-hand cold storageDevelopment prospect of simulation technology

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, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process so as to waste resources and increase the cost.The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Nubaris,It takes hours after the installation of the controlled atmosphere warehouse to deposit the goods, so as to quickly meet the temperature required by the goods and ensure that the controlled atmosphere warehouse equipment can operate normally.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.Kiwal,The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example, 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.How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, 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?Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.High value,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.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.Connect 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.

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,NubarisPreservation technology of vegetables in cold storage,NubarisInstallation of low temperature freezer,NubarisInstallation of large cold storage, 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.assets,The average service life of rigid polyurethane insulation structure with stable quality, or electrochemical corrosion it will not be affected by drying, as well as the growth of insects fungi or algae or rodents.Ammonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the system and lay a good foundation for the work of ammonia filling and thermal insulation materials of the system. After air leakage detection, some obvious leakage points can be found. However, due to the poor air permeability, the leakage points blocked by dirt along the tiny sand holes are not easy to be detected. Therefore, ammonia must be filled. In addition to good permeability, ammonia also has odor and is easy to be found, At the same time, phenolphthalein test paper can be used for leak detection because it is rose red in the presence of ammonia.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.Nubaris,What should be considered in building a cold storage? In these aspects, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.
