ABSTRACT:
An air diffuser that injects triangular columns of air into a space to be air conditioned. The triangular columns of air entrain air into their wake and set up a cross flow of air in a direction normal to the path of travel of the air in the triangular columns. In a first embodiment, a plurality of elongate, triangular nozzles are disposed at an angle in penetrating relation to a ceiling so that a first end of each nozzle is above the plane of the ceiling and a second end of each nozzle is below the plane. A housing in fluid communication with a source of air to be introduced into the space is positioned above the ceiling in housing relation to the respective first ends of the nozzles so that air introduced into the housing under positive pressure is constrained to exit the housing through the nozzles. In second and third embodiments, the nozzles are of differing geometrical configurations in transverse section and do not penetrate the plane of the panel within which they are mounted. In a fourth embodiment, ceiling-penetrating nozzles are inverted relative to their first embodiment position.
