The development direction and performance testing of kitchen exhaust fans

The development potential of kitchen exhaust fans has been drawing much attention in many enterprises and manufacturers, especially in China. This directly influences the development and strategic direction of domestic kitchen exhaust fan enterprises. From a domestic perspective, urbanization, industrialization, marketization, informatization and other international factors are intensifying. Development and greater economic restructuring. Especially China is currently in a very important stage of expanding domestic demand, accelerating infrastructure construction, industrial transformation and intensification. There is a huge market demand for kitchen exhaust fans and equipment. 

From the perspective of the industry itself, there are still many shortcomings compared to advanced foreign products. In order to ensure the reliability of the kitchen exhaust fan, enterprises must go through a strict design process before manufacturing the kitchen exhaust fan, controlling the problems and errors in the fan design within a small range. The losses can be controlled within a small range. This is also the guarantee for the development of kitchen exhaust fans in enterprises. 

Based on an understanding of the development potential of kitchen exhaust fans, the first step is to understand the performance testing methods for kitchen exhaust fans in the market. Taking the imported muffler kitchen exhaust fan as an example, the measured static pressure on the plane is equal to -296.3, -321.8, 2431.8, and the dynamic pressure on the plane is 532.32. The absolute pressure on the plane is equal to the applied static pressure to the atmospheric pressure. Please note that in the motor-related data, the adjustable internal guide device is in the fully open position, and the fan is directly connected to the motor. The motor manufacturer suggests that when the power factor is approximately 0.9, the high efficiency of this motor is 93. During the testing process, the authenticity of the data is related to the economic benefits. At the same time, if the exchange method is applied, the default auxiliary data needs to be replaced. Otherwise, the remaining values used in the last test will be displayed.
