Abstract
The system controls and distributes ventilation air in a building or room, having booster fans for forming air jets directing air by impulse into the room etc, in the desired direction. The jets are produced by nozzles connected to a separate small-diameter duct system containing the booster fans for increasing the air pressure. Part at least of the ventilation air is forced through a conditioning unit. The duct system delivers ambient air to the nozzles, and the conditioning units (5, 6, 7) are mounted in the rooms to be ventilated, comprising circulation units for the ventilation air delivered by the jets.
