Abstract (en)
[origin: EP0667495A1] The system has air consumers (1,3) which are all provided with a built-in air extraction regulator (2,6) and are adjusted to more or less the same pressure drop. The air consumers are connected to a single common air extraction channel (12) which forms the air extraction facility. A ventilation controller (8), to which are communicated the actual values of air extraction mix of the consumers, forms from them a regulated quantity for controlling the inlet air regulator (17) of the inlet air gallery (16).
