Abstract

A ventilation system for an interior space includes an air handling unit that moves air through the interior space and a return duct extending therefrom and having a return opening proximate to a floor of the interior space. The ventilation system also includes at least one perforated panel arranged beneath a ceiling of the interior space and a plenum defined between the ceiling and the at least one perforated panel, wherein the supply air outlet is in communication with the plenum to distribute air within the plenum and pressurize the plenum, such that air flow is induced through the at least one perforated panel as a high volume and low turbulence blanket of air that descends through the interior space and is received by the return opening in the return duct for recirculation through the air handling unit.
