the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.The refrigerant charge is insufficient. At this time,According to the technical requirements for the installation of cooling fan, when selecting the lifting point position, the position with good air circulation shall be considered first. Secondly, the direction of library structure is considered.The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight,San FranciscoCold storage medicine, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit,San FranciscoDrug cold storage installation, which allows the use of thinner plates during construction and saves building space.Umtata,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation, cold storage installation cold storage construction, fruit fresh-keeping cold storage, medical cold storage, complete products, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However, the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.

Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, the machine stops running under the action of the pressure controller. When the heat dissipation is good, and the machine can automatically resume operation.The air in the controlled atmosphere storage shall have appropriate circulating stream to make the air temperature in the storage uniform. If the circulation stream is not carried out, the air in the warehouse absorbs the respiratory heat of vegetables and the heat leakage of various parts which increases the upper temperature and is easy to deteriorate the products. Especially soon after vegetables are put into storage, it is more necessary to strengthen ventilation and circulation.The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.retailer,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.During the installation of polystyrene storehouse, the Perpendicularity Error of wall plate shall be corrected while the top storehouse plate is installed. The length of the top warehouse plate shall be mm shorter than the surface of the wall plate. After the installation of the top warehouse plate, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.
- precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).Honest management,The 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.Balance windows shall be provided for the fabricated controlled atmosphere storage.Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.San Francisco,The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan, which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses the mode of multiple heads in parallel can be considered.In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M,San FranciscoFrozen storage, and the polyurethane top storage plate (mm thick) has a span of m.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.
