Cold storage construction: which one is suitable for you? Which one is suitable for you?In the process of realizing your dream, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.Los Angeles Union,The installation of refrigeration pipeline requires that the diameter of copper pipe shall be selected in strict accordance with the interface of compressor suction and exhaust valve. When the separation between condenser and compressor exceeds M, the pipeline diameter shall be increased.Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.Arouca,Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, the machine stops running under the action of the pressure controller. When the heat dissipation is good, press the black reset button on the pressure controller, and the machine can automatically resume operation. - precautions for vertical plate of cold storage: vertical plate displayA large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.

With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore, the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?Frozen and refrigerated storage begins to shift to shelf and pallet storage in accordance with & amp; amp; ldquo； FIFO & amp; amp; rdquo； This is conducive to improving the quality of commodity storage and reducing losses.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?reform,Watertight polyurethane rigid foam has low water absorption, 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 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, 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.Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification,Los Angeles UnionVegetable fresh-keeping cold storage, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.

If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Packaging strategy,The refrigerant charge is insufficient. At this time, just add enough refrigerant.What are the common sense of protection and maintenance of fresh-keeping warehouse equipment? Nowadays, the application scope of fresh-keeping storehouse is more and more extensive. It is closely related to our daily life. In addition to food production factories, stores and restaurants have begun to build fresh-keeping storehouses. The main purpose of building a fresh-keeping warehouse is to ensure the freshness of food. There are many precautions in the process of fresh-keeping warehouse. After completion, there are also many protection and maintenance items. Regular maintenance and protection of fresh-keeping warehouse can increase its service life. Therefore, it is necessary for operators to understand some common knowledge about the protection and maintenance of fresh-keeping warehouse equipment. What are the common knowledge about the protection and maintenance of fresh-keeping warehouse equipment?When hot ammonia defrosting or electric defrosting is selected as the cooling fan, professional cold storage installation, cold storage installation, fruit preservation cold storage, medical cold storage, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted. Defrosting and drainage can be discharged immediately. Electric heat tracing and insulation can be selected for the defrosting and drainage pipeline of the warehouse location.Los Angeles Union,Los Angeles UnionLow temperature cold storage installation works,The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition, it shall be conducive to production, construction and dry ceremony.The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.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, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure,Los Angeles UnionWhere is a large cold storage, 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.
