We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, insulation effect and moisture-proof effect to form a vapor barrier layer.The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, so as to avoid the loss of refrigeration capacity of the cold storage.Bevellen,For the installation of power distribution system, each contact shall be installed with wire number for maintenance.Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.Mogoditshane,No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, 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.Advantages: no reciprocating motion,BevellenPrice and installation of cold storage project, so it has the advantages of simple structure, small volume, few parts (especially few vulnerable parts) and high reliability; Torque change is small. I am engaged in all kinds of cold storage installation, cold storage installation, cold storage construction, medical cold storage and other materials all year round. I operate in good faith. Welcome to call! High balance, low vibration, stable operation and low vibration of the whole machine; It has high efficiency and variable frequency speed regulation technology in the range of refrigeration capacity; The scroll refrigeration unit has no clearance volume, can maintain high volumetric efficiency, low operation noise, good stability and high safety, and is relatively not easy to liquid hammer.Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.assets,Refrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy, environmental protection and performance of cold storage.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, 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.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.

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,BevellenInstallation price of cold storage project, 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,BevellenHow much is a cold storage, 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.Manufacturing cost,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.The machine room shall be equipped with oxygen respirator, gas mask, gas clothing, rubber gloves, wooden stopper, pipe clamp, acid beverage and other necessary protective and rescue articles which shall be set in a convenient location, managed by a specially assigned person and used regularly. Relevant personnel shall skillfully master the use of oxygen respirator and personnel rescue.It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.Bevellen,The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, and the sealing performance will be reduced accordingly with the increase of the matching clearance The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.On the basis of cold storage and preservation, the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?
