Calculation of air volume

 Date:2022-01-24 02:00:37 Hits:363
How to calculate the fan air volume
The definition of fan air volume is the product of wind speed V and air duct cross-sectional area F
Because large fans can accurately measure the wind speed with anemometer, the air volume calculation is also very simple. The air volume can be calculated directly by using the formula q = VF
Determine the number of fans, calculate the total air volume required by the plant according to the ventilation times of the selected room, and then calculate the number of fans.
Calculation formula: n = v × N / Q, where: n - number of fans (set); V - site volume (M3); N -- ventilation rate (times / hour); Q - single air volume of the selected fan model (m3 / h).
The fan model shall be selected according to the actual situation of the plant, and the fan model matching the original window size shall be selected as far as possible. The fan shall be kept at a certain distance from the wet curtain (installed on both sides of the gable of the plant as far as possible) to achieve good ventilation effect. The exhaust side shall not be close to nearby buildings as far as possible to prevent affecting nearby residents.
If the air brought out from the room contains environmental pollution, a water spraying device can be installed at the air outlet to absorb the nearby pollutants for centralized recovery without polluting the environment
How to calculate the air volume and air pressure required by the induced draft fan 1. The first thing for the type selection of the induced draft fan is to determine the air volume; 2. The determination of air volume depends on what you do. The determination methods of air volume for different purposes are different. Please refer to books or consult technicians; 3. After determining the air volume, calculate the resistance along the way and local resistance section by section, add them and multiply them by the margin coefficient to obtain the required pressure; 4. Refer to the fan performance data sheet, or ask the fan manufacturer to find the corresponding fan model
