ConcepcionSmalThe 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, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
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.
Bridgetown.The customer specifies the refrigeration and conversion conditions required by the customer, the temperature of refrigeration and refrigerant, and the provisions of the customer's application site and application installation level.
Because polyurethane sheet has excellent thermal insulation performance it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
.The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.
Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.
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, and the 80mm wide color steel plate shall be sealed at the butt joint with pull riveting.
The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.
The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed 40 ℃ during unit operation or defrosting.
The bubble density is 38 kg to 40 kg / m3 per cubic meter, and the steel plate thickness generally needs to be more than 0.4 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, 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.
superior quality.Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.
How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.
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.
Establish a perfect computer network, make the distribution of refrigeration supply chain scientific,BridgetownInstallation of small cold storage, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.
reform.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.
The wholesale evaporator of the fresh-keeping storehouse is used as a cold absorber for the wholesale of the fresh-keeping storehouse. The wholesale evaporator of the fresh-keeping storehouse is installed in the room of the cold-keeping storehouse, connected to the low-pressure end of the compressor, and has been installed for all kinds of cold-keeping storehouses with high prices nationwide for a long time. The cold-keeping storehouse is installed, constructed, fruit fresh-keeping cold-keeping cold-keeping cold-keeping, medical cold-keeping cold-keeping cold-keeping, The refrigerant dissipated by the compressor is used for evaporation and gasification, and instantly becomes low temperature and low pressure through the throttling device, so as to achieve the purpose of refrigeration.
Strong deformation resistance,BridgetownSmall vegetable fresh-keeping storehouse, 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, 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.
Bridgetown.Various construction materials such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top,BridgetownWhich one to choose for cold storage installation, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
When the cold storage is built, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, professional cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, and have a long service life! Products lead the wire industry. Welcome to inquire, moisture-proof and steam isolation performance.
