Install the library body. Generally， the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat， compact and solid， without hollow feeling， load-bearing， antifreeze， moisture-proof， etc.
Strong deformation resistance， not easy to crack， smooth， stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance， but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions， the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period， it can reach the unit price of dry， wet or electric corrosion under normal service conditions， while the unit price of insect， fungus or algae foam material is higher than other traditional insulation materials， but heating will increase the cost and the cooling cost will be greatly reduced.
CardenasGood heat dissipation， good refrigeration. Do not stack sundries around the refrigeration unit The electrical equipment of the fresh-keeping warehouse equipment shall be protected from moisture and electric shock caused by electric leakage. The hinge， handle and door lock of the fresh-keeping storehouse shall be regularly added with oil according to the actual situation. The electrical equipment maintenance of the fresh-keeping storehouse equipment shall be operated by electricians or personnel who know the common sense of electricity. Any maintenance must cut off the power supply to ensure safety.
However， long-term continuous operation will inevitably lead to equipment aging， so reasonable maintenance is particularly important.
RashaudGeneral 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，CardenasHow much is the fruit preservation cold storage， so as to absorb the heat in the warehouse， so as to achieve the purpose of cooling and reduction.
The polyurethane insulation board used in the construction of cold storage shall be integral and continuous and there shall be no joint in the middle. The junction of polyurethane insulation board， top plate and ground shall be made into fillet arc for transition， which can well meet the health needs.
Watertight polyurethane rigid foam has low water absorption， good permeability to water vapor and state of foam pores. It is not connected with each other， which is more dense than the surface of the air， and is not easy to permeate. It is an hydrophobic material.
There are many application scenarios of cold storage， which are different. For a long time， it provides various cold storage installation， cold storage installation， cold storage construction， fruit preservation cold storage， medical cold storage， honest operation， and has offices all over the country for long-term cooperation. Different purposes， functions and designs， so what needs to be understood in cold storage design?
The overall layout of the unit is reasonable and the color is. The installation structure of each type of unit shall be consistent.
Fault phenomenon: fan motor overload， fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate， compressor line is disconnected， fuse is blown， thermal relay acts， high voltage switch acts， compressor is locked，CardenasHow much is a square meter for installing a cold storage， line is falsely connected or loose fault phenomenon: it stops in a short time after drying， ambient temperature is too high， condenser is blocked
Where can I find it?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， and then pouring concrete or reinforced concrete.
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， not easy to crack， smooth， stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance， but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions， the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period， it can reach the unit price of dry， wet or electric corrosion under normal service conditions， while the unit price of insect， fungus or algae foam material is higher than other traditional insulation materials， but heating will increase the cost and the cooling cost will be greatly reduced.
The ultrasonic town is a patented technology with a shaped energy cover， which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?
middlemanAnother 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 and then fill in sufficient refrigerant.
After the installation of the controlled atmosphere storage， the temperature is too low， perhaps because the unit is too large， which leads to the rapid decline of the air temperature in the controlled atmosphere storage. However， it can be found that the temperature of the goods is still at a high level， or perhaps because the thermal insulation effect of the controlled atmosphere storage is relatively poor after the installation of the controlled atmosphere storage， This phenomenon may be caused by the poor quality of the selected modified atmosphere storage board. It is suggested that when selecting the modified atmosphere storage board， we must pay attention to its thickness. Only the modified atmosphere storage board with the required thickness can have a certain thermal insulation effect.
The selection of cold storage is very important for cold storage， because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low， and the air temperature humidity and environmental requirements are relatively high. When selecting cold storage， attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good， the temperature in the cold storage is difficult to， which is easy to cause the deterioration of products in the cold storage， or the refrigeration compressor in the cold storage often works wasting more resources and increasing the cost.
CardenasFeatures 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.
If there is more air or refrigerant oil in the evaporator， the heat transfer coefficient will be reduced. Similarly， if there is more air in the heat transfer tube， the heat exchange area of the evaporator will be reduced， the heat transfer efficiency will be significantly reduced， and the decline rate of warehouse temperature will be slowed down.
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.
