However， long-term continuous operation will inevitably lead to equipment aging， so reasonable maintenance is particularly important.
Cold storage has good fire and flame resistance. After adding flame retardant， polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire， it can be carbonized， unlike flow burning and flashover like extruded board， which can effectively prevent fire spread. In particular， it can be closed as a whole after fire prevention treatment to form non combustible products.
SarovaThe area of wires in the conduit shall not exceed %.
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.
La hachoThe products stored in the medical cold storage project must be managed by color code， so as to avoid the problem of purchase errors. In the process of handling， it is also necessary to strictly follow the instructions.
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.
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， 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.
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.
If the warehouse is relatively small and you want to transform a miniature fruit fresh-keeping warehouse， you should ensure that the height in the warehouse is at least meters because the top of the cold storage and the top of the warehouse should reserve a height of at least cm.
All wiring shall be neat. All switches and keys shall be opened and closed sensitively， reliably and accurately. Special connectors shall be used for wiring， and power protection shall be provided for the box and each power branch.
Installation worksDanfoss thermal valve is adopted for the thermal valve of the cold storage， the temperature system of the cold storage adopts microcomputer full-automatic， and can be remotely controlled. When the temperature exceeds the specified range， it will automatically alarm， which is of great significance to the proper preservation of the cold storage.
More and more people begin to build cold storage， and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.
Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
The selection of cold storage is very important for cold storage， 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，SarovaMedical freezing， or the refrigeration compressor in the cold storage often works， wasting more resources and increasing the cost.
demandThe spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed， the wall panel joints shall be evenly sealed and decorated with silicone sealant.
After years of service， the refrigeration oil inside the compressor should be replaced. The oil， copper， iron and impurities caused by wear are mixed in the refrigeration system， which thickens the refrigeration oil， deteriorates the fluidity and performance， reduces the effect， takes a long time， increases the burden on the compressor and the current will increase relatively compared with the new machine， which is a bad phenomenon.
As a coolant， make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage， so as to achieve the purpose of cooling.
SarovaInstall the electric control system. The electric control system of the cold storage mainly includes electric controller， electric door， lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line，SarovaWhere is the fresh-keeping cold storage， and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.
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，SarovaHow much is the installation cost of small cold storage， more important is the choice of refrigeration system. For example， at present， 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.

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.
