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, ventilation, water and electricity systems. It should meet the requirements of safety,AlaihanHow much is a square meter for installing a cold storage, 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.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption good permeability to water vapor, disconnected and closed porosity of more than %. It is a dense microporous foam material foam holes,AlaihanPharmaceutical cold storage manufacturer, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.Alaihan,For the selection and preparation of the ground location of the cold storage, the design of the cold storage shall consider the necessary auxiliary engineering buildings and equipment, such as working intermediates, packaging and combing room, special tool warehouse, loading and unloading platform, etc.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationCaleta Olivia,Generally, 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, because it has higher strength when connecting in this way.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, fire and high temperature resistance, strong overload capacity, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.

Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight,AlaihanSmall medical cold storage, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.For the installation of refrigeration unit, oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - ℃, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.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 refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.Installation requirements,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.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.Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.

Cold storage is mainly used for frozen processing and storage of fooddevice management,Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.Evaporator is not only an exchanger for refrigeration and bulk cooling, but also a very important one. Its task is bulk cooling. It is mainly used for refrigeration and heat absorption in fresh-keeping warehouse. In the long-term work of the fresh-keeping warehouse, the fins of the evaporator will also be covered with dirt, mostly pasted with some sundries of the products. It is specialized in products and renewable resources. Its business includes: cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage. In addition, but reaching a certain thickness will have an impact on the cooling of the fresh-keeping warehouse, If the refrigeration of the fresh-keeping warehouse becomes poor, it should be cleaned with a special cleaning agent for the evaporator.The construction of small cold storage is widely used in life, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.Alaihan,The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, 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?Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.
