Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse,NivaraWhere to install cold storage, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.We should implement regular maintenance and daily maintenance, professional cold storage installation, installation of cold storage cold storage construction, fruit preservation cold storage medical cold storage, large quantity, fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable, and maintain the operation rate of the compressor.Nivara,The logistics cold storage project in the tally area belongs to the type of cold storage with frequent goods in and out and large quantity. Therefore, in order to keep the temperature fluctuation in the warehouse small, especially low-temperature logistics refrigerators, usually set up a special tally area according to business needs, and the temperature of the tally area is generally ~ ℃. In addition, a transfer room will be set in the logistics cold storage to avoid the loss of refrigeration capacity caused by frequent opening and closing of the cold storage door, or unqualified temperature and serious frosting.Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.Shijiazhuang City , that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.For the flushing (thawing) drainage pipe in the cold room with different temperature an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.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, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, 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.

The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.The ventilation device is adopted, which also produces heat exchange with the outside air, resulting in & amp; quot; Heat leakage & amp; quot;, Energy is wasted, so an air scrubber is required. Washing, amino, activated carbon, sieve, etc.During installation, 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.Variable cost,The height of the warehouse, 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 temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.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.

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.Safety production,The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.However, not all controlled atmosphere reservoirs can choose to adjust with a large depth, which still needs to be determined according to the actual needs of fans and places. We can adjust the energy-saving effect of the control fan from the production design link, coupled with the user's energy-saving effect of the hot air fan, so that the energy-saving effect of the hot air fan will be significantly improved.The ultrasonic town is a patented technology with a shaped energy cover, which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?Nivara,First, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time and the wedge iron shall be fixed with rivets.The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low,NivaraHow much is the installation of small cold storage, 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.Generally,NivaraInstallation of fruit and vegetable fresh-keeping cold storage, in the actual operation of the refrigeration system, because the temperature conditions are constantly changing, only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.
