ABSTRACT:
An air release box has at least one perforated bottom wall section and perforated longitudinal side wall sections. At least certain of the perforated wall sections, including the perforated bottom wall section, are equipped with spin air outlets for increasing the penetration depth of low turbulence air jets into a room. Without such spin air outlets the low turbulence air jets tend to be unstable at relatively low exit velocities. The tendency of these air jets to quickly decay is thus delayed. The highly turbulent air jets exiting from said spin air outlets do not entrain air in the room, but rather they entrain inlet air coming through the perforated wall sections neighboring the spin air outlets. Thus, the jet impulse imparts a high stability to the inlet air jets.
