Refrigeration 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.
In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.
London.In addition, water shortage or insufficient water in water-cooled machines will increase the exhaust temperature of the fresh-keeping warehouse. The condensation pressure is abnormal and the exhaust pressure of the fresh-keeping warehouse decreases.
During production in the production workshop, not less than 40 & plusmn; 2kg/m3.
.Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.
During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, replace it with new oil in time, so as to avoid bad compressor and reduce the service life of the compressor.
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.
Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
The shelves in the warehouse shall have sufficient strength and rigidity.
The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
Process inspection.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, and the opening and drilling shall be carried out after review; The inlet hole, liquid inlet hole return hole, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door 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, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of 300mm and 150mm outside.
It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.
Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.
Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.
Quality inspection report.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.
Disadvantages: high precision requirements, shape and position tolerances are in micron level; No exhaust valve, poor off design performance; The working chamber is not easy to implement external cooling, and the heat in the compression process is difficult, so it can only compress the gas with small adiabatic index or internal cooling; Large displacement scroll refrigeration unit is difficult to realize. The receiving teeth are high, the displacement is large, the diameter is large and the unbalanced rotation mass increases.
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.
London.Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
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, 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.
Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part
