The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown, thermal relay acts, high voltage switch acts compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedNyborg,The startup of the air-cooled refrigerator unit shall depend on whether the rotation direction of the fan is correct. If the forward rotation can be started for operation, the reverse rotation indicates that the power wiring is reversed, and the phase sequence must be replaced before startup.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, 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.Anloga,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.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,NyborgHow much does it cost to install a small cold storage, 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.Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.

However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Expensive, high machining precision of body parts; High noise during compressor operation; Screw compressor can only be used in medium and low pressure range, not in high-pressure occasions; Due to large fuel injection and complex oil treatment system there are many auxiliary equipment of the unit.Cold 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,NyborgDesign and installation of quick freezing cold storage, 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, which is characterized by very good temperature control effect and moderate cold storage.Manufacturing cost,Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance but also be economical, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.Here we focus on polyurethane.

To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.

Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large,Moreover, polyurethane does not produce harmful gas at high temperature.If the cold storage is in the building, after the fruit is loaded in the cold storage, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling load-bearing, antifreeze, moisture-proof, etc.Nyborg,Cold storage is mainly used for frozen processing and storage of foodWatertight polyurethane rigid foam has low water absorption,NyborgLarge and medium-sized cold storage installation company, good permeability to water vapor, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.
