How to calculate the air volume of industrial roof fans?

Do many people think that when choosing industrial roof fans, they should choose equipment with larger air volume for better use effect? ​​Is this true? In fact, the most important reference standard for choosing industrial roof fans depends on the environment you need to install them in, because the industrial fans with large air volume have larger fan blades, which is a proportional relationship. If you want the industrial roof fans you install to fully demonstrate their air volume advantages and achieve the best effect, then the choice of equipment model is very important.
Calculation method of industrial roof fan air volume: The definition of industrial roof fan air volume is: the product of wind speed V and cross-sectional area F. Large industrial fans can accurately measure wind speed with anemometers, so the air volume calculation is also very simple. The air volume can be calculated directly using the formula Q=VF. The number of fans is determined by calculating the number of fans according to the number of ventilation times. Calculation formula: N=V×n/Q Wherein: N--number of fans (units); V--site volume (m3); n--ventilation times (times/hour); Q--single-unit air volume of the selected fan model (m3/h). Using this calculation formula, we can get the same. Bergfin 7.3-meter industrial roof fan uses a permanent magnet servo synchronous motor, and the maximum air volume of a single unit can reach 15850 m3/min. As the fan blade diameter parameters change, the air volume will also change accordingly.
