Working Procedure:
The Ecoventilator works by utilizing the velocity energy of the wind to induce air flow by centrifugal action. The centrifugal force caused by the spinning vanes creates a region of low pressure area which draws and throws out hot air from below and fresh cool air from out side comes in. The slightest breeze will cause the turbine to spin and even after the breeze has stopped, the fly wheel effect of the rotor cage will use its stored energy to continuously remove air giving rise to ventilation. Suction is maintained even at low wind velocities. The Convective thermal current sare given boost by venturi dome to further enhance the rotation of the Ecoventilator.
