Abstract
A system includes a manifold, a power unit, and a throttle valve. The manifold is configured to receive cabin discharge air from a cabin. The cabin discharge air includes cabin discharge air from a waste region of the cabin. The auxiliary power unit is fluidically coupled to the manifold and configured to draw cabin discharge air from the manifold. The throttle valve is configured to control flow of cabin discharge air from the manifold to the power unit. A method includes receiving a pressure measurement for the manifold and a pressure setpoint for the manifold representing a predetermined flow of cabin discharge air from the cabin to the manifold. The method includes determining and outputting, based on the pressure measurement and the pressure setpoint, a control signal for at least one manifold inlet configured to control flow of cabin discharge air from the cabin to the manifold.
