Buenos-AiresWhCold 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, which is characterized by very good temperature control effect and moderate cold storage.
Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storage, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include 100mm, 150mm, 175mm and 200mm polyurethane thermal insulation boards, color steel tiles, stainless steel plates, salt thick steel plates, embossed aluminum plates, polyurethane spraying, etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble, and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases, and it is also easy to deform and damage the appearance.
FierCifci.For the installation of power distribution system, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
.The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course,FierCifciFresh keeping cold storage installation manufacturer, if the height of the warehouse is high and the forklift is required for warehousing loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity,FierCifciRefrigeration equipment of medical cold storage, ton cubic meter, frame, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear, such as refrigeration compressors, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers doors, temperatures and other refrigeration equipment.
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.
The wholesale electronic control system of fresh-keeping storehouse is the main component of the wholesale intelligent system of fresh-keeping storehouse. The intelligent electronic control has the functions of automatic cooling, heat preservation, stop, defrosting, delay and other related functions. The electronic control humanized mode saves the complicated work of manual operation. The wholesale seafood machine of fresh-keeping storehouse is used for seafood breeding and other temperature systems. The principle is similar to that of air conditioning. The main components are titanium barrel, fan, condenser, compressor, temperature controller, through valve and other components. Next, fresh-keeping warehouse wholesale is introduced in detail
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,FierCifciFruit preservation cold storage money, 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.
agent.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, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.
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, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with 0.5 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 300mm; 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.
The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
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 foundation construction is complex. High cost; When prefabricated components are used large construction equipment is required and the construction period is long.
Job description.For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation, but its energy consumption is very large in the use of cold storage. How can we solve this problem?
After the refrigeration system is installed, it shall be beautiful and color. There shall be no cross height inequality of pipelines.
