CuaWhere is a good place to install cold storageExorbitant form

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,CuaDesign of fruit fresh-keeping storehouse, 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.

The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, the operation energy consumption will increase.

The selection of cold storage is very important for cold storage the temperature difference of room air conditioner is between 12C and 14C. If the temperature difference cannot be maintained due to adverse factors, 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.

.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.

The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.

In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.

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 500 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.

Electrothermal defrosting: the electrothermal element defrosts the controlled atmosphere reservoir. The management system of controlled atmosphere storage is simple, easy to operate, easy to realize automation, but it consumes more power.

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 30 years. During the structural life period, while the unit price of insect wet or electric corrosion under normal service conditions, 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.

Quality Assurance.2. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.

The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.

The 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,CuaInstallation of industrial cold storage, and the 80mm wide color steel plate shall be sealed at the butt joint with pull riveting.

Emergency measures during the use of the medical cold storage project,CuaWhere to install cold storage specialty, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.

Equipment maintenance.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?

The water-cooled cold storage shall keep the cooling water tower clean and keep the air around the water tower circulating with low temperature, so as to avoid sundries from entering the cooling tower and reduce the heat dissipation efficiency.

There is a slight sag on the cold insulation board to prevent damage to the cold storage. When standing on the wall, some soft materials should be laid on the floor of the cold storage tank.

Cua.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, 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.

The quantity is large, and a special tally room (area) is set according to the needs of production and operation. The temperature of the tally area is usually controlled at 0 ~ + 7 ℃.

Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.
