Ventilation Fan Power
Several factors should be taken into account when choosing the right fan for any particular problem: Hence, the difference in temperature
The height of the foot (chimney effect)
Induction effect of the wind
Area of the fan opening Several other small factors, only one requires close attention. This is an area with inlet air holes (Fig. 3-4). The action of the fan-let the air from the top of the building, which, naturally, means that as the amount of air should be allowed to enter the building to take the place of the removed air. The nature, size and location of these inlets are important to determining the effectiveness of the ventilation system.
