<p>The method involves sucking air (4) from a room at a suction funnel (1), where a laminar, bundled air jet (3) is blown into the room at a nozzle (2), and the air jet is directed towards the suction funnel. The loaded air is diluted and/or cooled and/or warmed up by the bundled air jet. The nozzle has a circular cross section and possesses a conical opening. The suction funnel is installed under a ceiling of an area, at which an exhaust fan is attached. An independent claim is also included for a device for removing loaded air.</p> |
