In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room,MontrealManufacturer installing large cold storage, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.Product survey,The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle,MontrealCold storage board installation, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.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.Features 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.Montreal,Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin,MontrealInstall fruit preservation cold storage, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Another 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
