WIND VENTILATORS

Shrijee Heavy Projects offers Wind Ventilators. It is a combination of both natural and forced ventilation system. It functions as a natural ventilator when there is a difference in thermal or wind pressure between the inside and outside of the building which forces the air to move through the openings of the ventilators. It also acts as a forced ventilation system when the ventilator rotates to create a negative pressure space in the building inorder to maintain an equilibrium condition. The ventilator operates by harnessing the full, velocity energy of the wind to induce an air flow by centrifugal action. Because the air-foil vanes are, lightweight and dynamically balanced, even a slight, breeze will spin the ventilator. When the ventilator rotates, a centrifugal force is created, which then draws the air in the ventilator towards the spinning vanes and out of the ventilator. As the ventilator rotates, the air-foil vanes act as cups which catch the wind at the windward side of the ventilator. Simultaneously, air is forced out at the leeward side creating a continuous airflow. Thus giving rise to ventilation.
