Wind Turbine ventilators are powered by the wind to create effective ventilation for different industries. The mechanics involved in the air movement is very simple. The hot air inside the shed tends to rise up. When the turbines rotate, they suck the warm air out through the vent, thereby, bringing out a drop in temperature in the shed and allow supply of fresh air through doors and windows.
They have several advantages which include that they do not need to be powered by electricity, they are located such that they exhaust the hottest air first, they do not cause any harm what so ever to the environment, they tend to save a lot of money because there is no operating cost plus they are maintenance free. The size, number and installation all depend on different factors which include wind velocity, temperature differential, environment conditions, and the size of the building.
