AIR DISTRIBUTION SYSTEM

摘要

An air distribution system for a building including a mixing plenum for receiving and mixing outside and return air. An input flow concentrator and integral silencer is disposed within and coupled to the mixing plenum. The flow concentrator and integral silencer is adapted to establish a substantially axially symmetrical flow path for air from the plenum to an output port. A fan is coupled to the output port to drive the air from the output port to the main duct for distribution throughout the building.
