ABSTRACT:
A low-noise nozzle system for receiving an air flow from a relatively low-velocity, high-volume air source and for producing therefrom a high-velocity, low-volume jet of air for delivery into a room to control the distribution of air in the room. The nozzle inner walls first extend along a straight axis into the room, then bend gradually at right angles to feed an outlet aperture which injects the jet into the room at right angles to the axis. The aperture is in a plane parallel to said straight axis and elongated at right angles to said axis; low-noise delivery of the jet into the room is accomplished by special proportioning of the radii of the nozzle inner walls at the bend in relation to the size of the inlet to the nozzle, and of the size of the outlet aperture relative to the size of said nozzle inlet.
