Abstract
A ventilation system for an interior room is provided, having a first air suction device, a second air suction device, a suction volume control device, a first air conduction pipe, a second air conduction pipe, a vacuum generating device and a control unit. The suction volume control device affects an air flow from the first and the second air suction device to the first and the second air conduction pipe, respectively, wherein the control unit controls the suction volume control device so that the air flow from the first air suction device to the first air conduction pipe is controllable.
