AN EXHAUST AND SUCTION GRILL FOR NATURAL VENTILATING

摘要

PURPOSE: An exhaust and suction grill for natural ventilation is provided to reduce the energy by performing the ventilation without excessively using a suction fan or an exhaust fan. CONSTITUTION: An exhaust and suction grill for natural ventilation comprises the intake wing(110), a cover(120), and a suction grill(100). The cover is installed at the upper of the intake wing. The wind blowing from every direction strikes against the intake wing and flows into a suction pipe(30). The suction grill is installed at the entrance of the suction pipe. An exhaust pipe is connected to the center of the ventilation passage of an exhaust grill. The width of the center of the ventilation passage of the exhaust air grill is narrow and becomes wider as the distance from the center is far. A damper(150) controlling the aperture ratio is installed at the back end of the intake wing.
