DahaonCold storage installation companyChoose what to pay attention to

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.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.Dahaon,The air-conditioned storage is relatively fast. It usually reaches the required temperature, according to the temperature of the environment, refrigeration is also divided into air cooling, water cooling, direct cooling and simple cooling. Different refrigeration is fast and slow, but most small refrigerators are air-cooled,DahaonInstallation video of small cold storage, The market share is about %.. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor,DahaonInstallation of fruit and vegetable fresh-keeping cold storage, and relevant signs shall be set. If the mechanical panel is set in the main room,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.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan, which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the mode of multiple heads in parallel can be considered.

Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.Before the warehouse is fixed with angle aluminum, it shall be sealed with glass glue and fixed with angle aluminum with solid pull Mao. The distance between pull rivets is mm. The distance between the upper and lower sides of the door is mm.When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.Product survey,The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.The 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, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.

Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting,DahaonCold storage installation company, ventilation, water and electricity systems. It should meet the requirements of safety science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.supply,The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, 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 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, it is more necessary to store the temperature and time of goods entering and leaving the warehouse. Introduction to KFC refrigeration: logistics refrigerators with frequent incoming and outgoing goods and large throughput 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.Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, because the temperature difference inside and outside the board is large, and the temperature will disperse, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.Dahaon,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Strong deformation resistance, 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 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.The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.
