Verfahren und Vorrichtung zur Rauchgas- und Wärmeabsaugung sowie zur Betriebslüftung für Verkehrsbauten und Räume

摘要

The invention relates to a method and a device for extracting fumes and heat and for providing operational ventilation for traffic structures and enclosed traffic spaces. The inventive system for drawing off fumes and heat and for providing operational ventilation for traffic structures and enclosed traffic spaces does not use any pipe ventilators for extracting the fumes and builds up a vacuum throughout the entire extraction channel in order to extract the fumes. The system is characterised in that a number of reversible jet ventilators (3) are provided inside a modular smoke extraction channel (2) situated preferably beneath the tunnel roof (1) or the roof of an enclosed space. The jet ventilators are evenly distributed over the length of said channel and the channel itself has evenly distributed roof openings (2a). Said jet ventilators are able to rapidly accelerate the air or the fumes of a fire (5) on the road (8) in a particular direction in the smoke extraction channel by virtue of an impulse effect (3a).
