Before the acceptance and delivery of the project， the board surface shall be wiped clean. If there is any scratch， it shall be treated. There shall be no obvious scratch on the board surface.
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.
SaguarragrandTherefore， the cold storage also needs regular maintenance every year， good permeability to water vapor， foam holes， disconnected and closed porosity of more than %. It is a dense microporous foam material， which is more dense than air surface， and is not easy to permeate. It belongs to hydrophobic materials.
MangoImmediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment， use the volatilization of the refrigerant to immediately cool the air in the air， and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed， so it is widely used.
Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.
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.
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.
The selection of wires shall have a safety factor， and the temperature of the wire surface shall not exceed ℃ during unit operation or defrosting.
Goods are imported and exported frequently and the throughput is large according to the requirements of production and operation
Packaging strategyThe cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference， so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.
Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m， the thermal conductivity is only . ~ .w / (m.k)， which is the lowest among all thermal insulation materials at present.
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.
These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage， which makes people"s retained items more convenient and reliable. With the continuous development of material technology， today"s various cold storage materials emerge in endlessly， and the cold storage is different from each other. When purchasing， we should make reasonable comparison and select products suitable for our own use needs and economic conditions.
recommendGeneral quick-frozen warehouses are mostly cooled by refrigeration mechanisms，SaguarragrandInstallation of cold storage， 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，SaguarragrandFrozen storage， so as to achieve the purpose of cooling and reduction.
Building plan and other relevant data of cold storage construction project.
The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity，SaguarragrandFood cold storage installation manufacturer， 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.
SaguarragrandGenerally speaking， the construction of cold storage is to ensure the quality of buildings with its strict heat insulation， sealing， firmness and frost resistance.
Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory， the temperature and temperature difference parameters of the cold storage shall be customized according to the user"s requirements. After understanding the technical parameters of the cold storage， set the parameters on the refrigerator. During use， the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include mm， mm， mm， mm and mm polyurethane thermal insulation boards， color steel tiles stainless steel plates， salt thick steel plates， polyurethane spraying， etc. on both sides or single and double sides， more general color steel tiles are produced and processed into hidden grooves， which have light weight， high compressive strength， good fire resistance， corrosion resistance and aging resistance， and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases， and it is also easy to deform and damage the appearance.
