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.

[ What is claimed is:] [1.]1. An air handling system for a building having a horizontally extending ceiling and an enclosed space below said ceiling, said system comprising:two induction units adapted for mounting adjacent said ceiling, each of said units having an air mixing section forming a relatively long air mixing chamber, an elongate, horizontally extending air plenum section mounted at an upper end of said air mixing chamber and having a primary air inlet formed therein, and air nozzles extending into said air mixing chamber and mounted on a side of said air plenum section, said air nozzles having each an inlet end opening into an interior chamber of said air plenum section, wherein said air mixing section has an air outlet formed at a lower end thereof and a side air inlet for permitting return air to flow through a side of said air mixing section and into said air mixing chamber; andsupporting members for mounting said two induction units so that each air mixing section extends at a substantial acute angle to said ceiling and is located adjacent said ceiling during use of the system in the building,wherein during use of said system, said return air is drawn by a venturi effect created by said nozzles into each air mixing chamber and said two induction units are capable of delivering a mixture of primary air, that passes through their plenum sections and said nozzles, and return air through the air outlets to said enclosed air space.
