Abstract
A displacement ventilation system for a room includes a first duct located inside the room and extending between a floor and a ceiling of the room, an air inlet coupled with the first duct for drawing air into the 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 system includes a return air duct extending adjacent the ceiling and being coupled with the first duct for removing return air from the room and advancing the return air toward the first 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. The system includes sensors located inside the room, and a controller for controlling operation of the system. The controller is in communication with the sensors.
