Abstract: An air diffuser for an air outlet. The air diffuser is mounted to a ceiling or wall surface and has an inner plate member with an opening communicating with the air outlet. A plurality of nozzles extend from the inner plate member and are positioned at predetermined intervals around the periphery of the inner plate member. An outer plate member is fastened to the inner plate member so as to sandwich the nozzles therebetween.

Abstract: An air diffuser for a ceiling or wall conditioned air outlet. The diffuser has a plurality of nozzles separating the flow of air from the outlet to the ambient into a plurality of diverging air jet streams, with the result that air flowing from the outlet is diffused and substantially uniformly distributed throughout an enclosure, without causing uncomfortable drafts.

Abstract: An air circulation apparatus provided with a plurality of outlet nozzles separating the air flowing from the air circulation apparatus into a plurality of diverging air jet streams. The air circulation apparatus may take the form of a recirculation blower, an air space heater, or a room air conditioner.

Abstract: An air diffuser for a ceiling or wall conditioned air outlet. The diffuser separates the flow of air from the outlet to the ambient into a plurality of diverging air jet streams by means of a plurality of regularly disposed wedge-shaped fins, with the result that air flowing from the outlet is diffused and substantially uniformly distributed throughout an enclosure, without causing uncomfortable drafts. Additionally, the ceiling type diffuser of the invention is preferably provided with a conically shaped baffle disposed across the direct flow of air from the outlet, and causing the air to be evenly distributed through the apertures between consecutive wedge-shaped fins and directed evenly along the ceiling and at a small angle downwardly.
