Abstract
An indirect/direct evaporative cooling system for cooling air for comfort purposes includes a single, variable speed blower positioned below an indirect evaporative cooling stage and a direct evaporative cooling stage. A first portion of the blower discharge is directed horizontally through the indirect evaporative cooling stage, where it is cooled without the addition of moisture thereto, and is then further cooled in the direct evaporative stage prior to being supplied to a building. A second portion of the blower discharge is directed vertically through the indirect evaporative cooling stage and serves to cool the first portion as the first portion travels through the indirect stage. The indirect and direct cooling stages share a common sump for collecting water drained therefrom. The indirect stage includes a drip edge to keep drain water out of the flow of the first portion. A stud-straddle supply duct is attached to the direct cooling stage to facilitate installation of the system in wood-framed walls.
