When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.Wanamint,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.With the development of the times, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need to grasp its key points in the production process of cold storage.Naantali,Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even in the work, the water temperature is lowThe 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 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,WanamintConstant temperature medical cold storage, 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.The stacking and arrangement of cargo stacks in the controlled atmosphere warehouse have a great impact on the air circulation. A basic principle of air flow is to take the path with low resistance to obtain large air flow. If there is a dead corner caused by stacking obstruction and air circulation is difficult, the temperature will rise. For this reason, there shall be gaps between the cargo stacks and between the cargo stacks and the wall. The stacking arrangement of the cargo stacks shall be coordinated with the ventilation arrangement.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,The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldLarge space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes, which increases the space a lot.

Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large,WanamintCold storage for fruit, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate,The water tank is designed to be separated from the machine body and is double-layer. It will not drip due to condensation caused by internal and external temperature difference. It can be interlocked with the refrigeration system, that is, it will not be humidified during refrigeration to prevent serious frosting of the fan.The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. The warehouse has a wide range of temperature control. The selection, layout and wind speed field description of refrigeration equipment are suitable for the refrigeration needs of various goods. Equipped with perfect storage temperature active detection, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board, and tighten the angle iron parts until there is a hole on the insulation boardWanamint,There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm,WanamintCold storage installation where to find, without color requirements; The thickness of PE paint baking board is .mm .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa, WB and W.Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads, railways, etc. At the same time the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.
