[China Aluminum Network] and everyone together to comprehensively analyze the characteristics and advantages of cold storage evaporator aluminum row, for everyone to uncover the mystery of aluminum row. Why use aluminum row as a cold storage evaporator? Because the aluminum row has good thermal conductivity, the evaporator of the cold storage refrigeration system using the aluminum row can save more than 30% energy compared with the conventional steel row and cooling fan. The projected area and evaporation area ratio of the aluminum row can be 1:3 or 1:4, and can be installed on the top surface of the cold storage. In this way, the heat exchange capacity per unit area can be higher and more energy-efficient than the use of wall discharge, and there is also a certain effect of cold storage, so that the frequent start-up rate of the compressor during operation is reduced, the service life of the compressor is prolonged, and a certain amount of electrical energy is saved. Consumption. At the same time, the aluminum row also has the characteristics of light weight, easy installation and low refrigerant consumption. So many cold storage builders chose to use aluminum rows as evaporators for cold storage. What are the advantages of aluminum row? Good thermal conductivity Aluminum alloy has excellent thermal conductivity. At this time, the evaporating temperature of the refrigerant and the temperature difference of the aluminum outer surface will decrease, the evaporation temperature will increase, the energy efficiency ratio of the compressor will increase, and the energy consumption will decrease. Take the frost source aluminum row as an example, its raw material is pure aluminum ingot, so its thermal conductivity is 237W/mk. More than 30% energy saving than other evaporator products. Special structure design cooling and cooling fast The fins of the aluminum alloy fin tube are parallel to the aluminum tube to form a sheet shape. The formed aluminum row fixes the sheet fin tube in parallel to form a number of parallel channels. When the refrigeration system is working, cold air forms a flue in the passage. The effect is accelerated and sinks, and the convection speeds up, so the cooling rate is fast. When the set temperature is reached, the compressor stops running, saving a lot of power. Taking the frosted aluminum row as an example, its special structural design enables the cooling system to quickly reach the set temperature in a short period of time. In addition, the unique process in the aluminum pipe can ensure the cleanliness of the aluminum pipe. The use of acid sand technology on the surface of the aluminum tube ensures its air tightness, forms an oxidized protective film, and prolongs the service life of the aluminum row. It has been learned that there have never been any problems with the use of frost-sourced aluminium bars in the Xiangjiang Hotel's cold storage room in Xingtai for a full 10 years. High heat transfer efficiency with cold storage The reporter understands that the ratio of the projection area and evaporation area of ​​the aluminum row can be one to three or one to four and can be installed on the top surface of the cold storage, which can make the unit area's heat exchange capacity more efficient and energy-efficient than using the wall row. And at this time, the aluminum bank has a certain cold storage effect, which can reduce the frequent start-up rate when the compressor is working and extend the service life of the compressor. The situation of the use of frost-source aluminum customers learned by reporters shows that, so far, there has been no case of frost-sourced aluminum rows in which refrigeration compressors cannot operate normally due to aluminum displacement. Light weight, easy installation and less refrigerant The density of pure aluminum is 2.7g/cm3. Compared with other evaporator materials, the weight per unit area is lighter and therefore easier to install. As is well known, the fin tube used in the frosted aluminum row is the inner fin structure of the outer fins, and the refrigerant charging amount is greatly reduced, which can save the cost of the refrigerant. Low food consumption The aluminum row is installed at the top of the warehouse to form direct-cooled natural convection heat transfer, which reduces the consumption of dried foods to less. The dry food consumption of the food is intensified when the compressor is in operation, and is relieved when the compressor is stopped. Due to the extremely fast cooling rate of the aluminum exhaust, the shortening of the compressor working time and the long downtime, the cold storage made using this aluminum row is compared with the traditional cold storage, and the food is dried. Less consumption, better food preservation effect, less frost on the aluminum row, so that the humidity in the warehouse is moderate, the temperature is stable, and the constant temperature and humidity are good. For example, the aluminum source of frost source is often used in food cold storage, including: grape cold storage, fragrant pear cold storage, pepper cold storage, logistics cold storage and so on. The reporter learned that the cream source aluminum eliminates the above-mentioned characteristics, but also ingenuity in the welding process using tungsten pulse argon arc welding, not only damage the original aluminum row structure, but also to ensure its airtight, in appearance Clean and beautiful. In the pressure leak detection, the frost source aluminum row pressured with nitrogen, can be a good guarantee of the aluminum row of air tightness, pressure resistance, let it eliminate the risk of leakage. In terms of product design, the design of the frost-source aluminum row is flexible and can be skillfully used in various types of cold storage, and the energy-saving effect is obvious. The next issue of aluminum emissions fog, the reporter will take everyone to understand, how to suppress the aluminum discharge to ensure that it does not leak?
