WIND TURBINE VENTILATION

The turbine ventilator operates by harnessing the full velocity energy of the wind to include an air flow by centrifugal action. Because the air-foil vanes are lightweight and dynamically balanced, even a slight breeze will spin the turbine.
When the turbine rotates, a centrifugal force is created, which then draws the air in the turbines towards the spinning vanes and out of the turbine.
As the turbine rotates, the air-foil vanes act as cups which catch the wind at the windward side of the turbine. Simultaneously, air is forced out of the leeward side creating a continuous air-flow. Thus giving rise to ventilation.
When air is drawn out of the turbine, a region of low pressure is created directly under the turbine relative to the other areas of the building.
As there is a difference in the air pressure, air from higher pressure regions will naturally move towards the lower pressure regions to maintain a state of equilibrium.
Air drawn out by the ventilators is continuously replaced by fresh air from outside the building. Therefore, it is important to have intake of about 150% or more of the overall exhaust opening of the building.
Since the turbine is rotating continuously, this air-flow is also continuous, resulting in effective ventilation.
