    What is the working principle of the cooling plate Introduction to the working principle of the cooling plate【Detailed explanation】

    What is the working principle of the cooling plate Introduction to the working principle of the cooling plate【Detailed explanation】 With the continuous development of technology, refrigeration equipment such as air conditioners have played a great role in our production and life. Everyone knows that air conditioning can be used for cooling, but they don’t know much about the cooling fins that play a key role. How does the cooling fins achieve the cooling effect? Then today we will introduce some cooling of the cooling fins. Principles for everyone to understand. The working principle of cooling plate 　　 The main equipment of absorption chillers are: generator, condenser, evaporator, absorber, throttle mechanism, solution heat exchanger and solution pump. In the generator, the lithium bromide solution with lower concentration is heated to evaporate the water in the solution, and the solution is concentrated. The concentrated solution is sent to the absorber, and the water vapor enters the condenser to condense into refrigerant water. The refrigerant water is reduced in pressure by the throttling mechanism and then enters the evaporator to evaporate and absorb heat to produce cooling capacity, which is then absorbed by the solution in the absorber. 　　 The single unit has a large cooling capacity. When the cooling capacity is the same, it has a small volume, a small footprint, and a weight 5-8 times lighter than the piston type. Because it has no wearing parts such as steam valve piston ring and no crank connecting rod mechanism, it has reliable operation, smooth operation, low noise, simple operation and low maintenance cost. There is no friction between the working wheel and the casing, and no lubrication is required. Therefore, the refrigerant vapor does not contact with the lubricating oil, thereby improving the heat transfer performance of the evaporator and the condenser. The cooling capacity can be adjusted economically and conveniently and the adjustment range is large. The adaptability to refrigerant is poor, and a centrifugal refrigeration compressor with a certain structure can only adapt to one refrigerant. Because it is suitable to use a refrigerant with a relatively large molecular weight, it is only suitable for a large cooling capacity, which is generally more than 250,000 to 300,000 kcal/hour. If the cooling capacity is too small, the flow rate is required to be small and the flow path is narrow, so that the resistance to activity is large and the efficiency is low. But in recent years, after perfection, the centrifugal refrigeration compressor used for air conditioning, the single unit cooling capacity can be as small as 100,000 kcal/hour. The outdoor refrigeration unit cools down (or heats up) the cold (hot) medium water, and then the cooled pump (hot) water is transported by the water pump to the fan coil unit installed indoors, which is taken by the fan coil unit In-place return air exchanges heat with indoor air to achieve indoor air treatment. Some of the content described above is a detailed introduction to the working principle of the cooling plate. You can understand from the above. In our refrigeration equipment, the role of the cooling plate is very critical and very important. Everyone must have more Understand this aspect, in order to better use these refrigeration equipment.
