Abstract
An air handling system for a building having a ceiling and enclosed space, the system including four interconnected induction units for mounting adjacent the ceiling. These units form four sides of a rectangular assembly. Each induction unit includes an air plenum section and an air mixing section connected to a side of the air plenum section and forming an elongate air mixing chamber that extends downwardly to an air outlet. Supporting members mount the induction unit assembly at the ceiling so that each air mixing section when viewed in transverse, vertical cross-section extends at a substantial angle, which in a preferred embodiment is about 90 degrees, to the ceiling during use of the apparatus. Return air is drawn by venturi effect created by a fast flow of primary air into each air mixing chamber and heated or cooled at the heat exchanging coils. The units can provide a mixed air flow that flows downwardly from the outlets.
