Abstract
A displacement ventilation system includes a vertical duct located inside an enclosed space and extending between a floor and a ceiling of the enclosed space, an air inlet coupled with the vertical duct for drawing air into the displacement ventilation system, and an elongated diffuser extending adjacent the floor for diffusing at least some of the outside air over the floor of the enclosed spaced. The displacement ventilation system desirably includes a return air duct extending adjacent the ceiling and being coupled with the vertical duct for removing return air from the enclosed space and advancing the return air toward the vertical duct, a heat exchanger for transferring thermal energy between the return air and the outside air, and a heat pump for changing a temperature level of the outside air or the return air passing through the heat pump.
