ABSTRACT:
The present air diffuser has a generally rectangular bottom panel mounted immediately below the outlet of a ceiling air duct. Along each side an inverted wedge strip is positioned to project across the ceiling a coherent blanket of the supply air which has been deflected horizontally outward by the bottom panel. The wedges are arranged to substantially equalize the air supply along each side, avoiding air "starvation" at the corners, thus providing a continuous coherent blanket of radial air flow. At the downstream side of each wedge strip, the altitude of each inverted wedge at its apex is substantially twice its spacing there from the bottom panel, in order to project the desired coherent blanket of air. The base of each wedge strip and the adjacent periphery of the bottom panel are inclined downward and outward to accomplish rapid induction and velocity reduction before the coherent blanket returns to the ceiling, assuring fast temperature blending and avoiding ceiling soilage. The bottom panel has a double wall construction to avoid moisture condensation and drippage from the bottom.
