The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.Sanhe,We also need to maintain the wholesale storeboards of fresh-keeping storehouses regularly. For example, in the daily use of fresh-keeping warehouse wholesale we should avoid scratching or collision caused by objects on the warehouse board. The purpose of this is to avoid dents and scratches after the wholesale warehouse board of fresh-keeping warehouse is impacted. In serious cases, it may also affect the refrigeration effect of fresh-keeping warehouse wholesale, resulting in the reduction of local temperature control effect of cold storage.Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.Kerman,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.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.There are many kinds of cold storage. According to the material it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm vertical angle plate W = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa, WB and W.

Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.Fresh keeping storehouse is a building with artificial refrigeration to make the fixed space reach the specified temperature and facilitate the storage of goods. Fresh keeping warehouse wholesale can be widely used in food factories, dairy factories, factories, and so on. The following are the functions of the main parts of the fresh-keeping warehouse wholesale.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.Latest quotation, ensure that its surface is smooth and flat without scratch and warpage.For cold storage, but its energy consumption is very large in the use of cold storage. How can we solve this problem?During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.

Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, and unqualified products are not allowed to leave the factory.Project scope,According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, so that it can become a whole.Because our large-scale fresh-keeping warehouse is generally composed of many thermal insulation boards,SanheInstall cold storage by yourself, and the gap between each board is the place that needs maintenance. During construction, these gaps will generally be sealed with sealant, but if it is found that there are seal failure departments in the fresh-keeping warehouse during use, they need to be repaired in time.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldSanheThe average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure,SanheWhere is the cold storage company, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance,SanheFreezer, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.
