Strong deformation resistance, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance,Kingston ParkThat's good, 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 years. During the structural life period, it can reach the unit price of dry, 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.When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.Kingston Park,The type of cold storage to be built in the cold storage type shall be determined according to the type of circulating goods. For example, a cold storage that only circulates vegetables can only establish a fresh-keeping cold storage. If there are many kinds of circulating commodities and large differences in storage temperatures a cold storage of refrigeration + freezing will be established. As for the size of the cold storage, it shall be determined according to the type, quantity, frequency, cycle, whether to use shelves for stacking, etc. For example, for fruits and vegetables packed in cartons, refer to the storage capacity of -kg per cubic meter, andThe service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.Wuhan,The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.During the use of the goods yard medical cold storage project, the stored goods must be in strict accordance with the relevant regulations. The goods should have a certain distance from the ground and wall of the cold storage. When stacking, the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular,Kingston ParkHow much does it cost to install the cold storage, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.
Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.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.At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.demand,Cold storage, compressor overload, lack of refrigerant, low pressure too low excessive air intake, compressor jamming.Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, environmental protection and performance of cold storage.
The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.total cost,The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.Check whether the compressor phase current is stable.Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, installation of cold storage, medical cold storage fruit preservation cold storage,Kingston ParkFresh keeping quick freezing warehouse, quality assurance, professional, timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.Kingston Park,Danfoss thermal valve is adopted for the thermal valve of the cold storage with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, 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.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.
