Venturi type air distribution system

摘要

An air handling system for an enclosed space in a building includes two induction units that can be mounted above a ceiling. Each unit has an elongate air plenum section and an air mixing section forming an air mixing chamber. Air nozzles extend into the air mixing chamber and are mounted on a side of the air plenum section. Each nozzle has an inlet end opening into an interior chamber of the plenum section. Each air mixing section has an air outlet formed at a lower end thereof and a side air inlet for permitting return air to flow into the mixing chamber. Each induction unit is mounted so that the air mixing section extends at a substantial acute angle to the ceiling with the air outlet positioned where the mixing section meets the ceiling. The return air is drawn by a venturi effect created by the nozzles into each mixing chamber.
