PURPOSE:To enable constantly a proper ventilation by a method wherein a flow amount to be discharged to the outdoor side through an inducing fan and a flow amount of pressed air are operated by an operation means, and the flow amount of the pressed air is controlled by a flow amount control means based on an operation signal. CONSTITUTION:One end of an air inducing fan 1 which is arranged in a ceiling rearside 3 of a building is connected in communication through a first duct 7 to a suction port 6 which is provided in a ceiling surface 5 of a room 4, and the other end of the inducing fan 1 is connected in communication through a second duct 10 to an air discharge port 9 which is provided in the external wall 8 of the building 2. When it is detected that a person is in the room 4 by a sensor 24 to detect a state of the room 4, an operation circuit 25, formed of a micro-computer and the like, operates a flow amount of air to be discharged to the outdoor side and also a flow amount of pressed air to be supplied to the air inducing fan 1. Based on these operation results, a gap width of the air inducing fan 1 is obtained by a flow amount control circuit 26, and the gap width is transmitted to the air inducing fan 1 as a control signal. By controlling the gap width, the flow amount of the pressed air can be controlled to keep a prescribed amount of air to be discharged without fail.
