Abstract
A compact air handling system includes an inlet channel which defines an inlet flow path in a first direction along a flow axis and a discharge channel which defines a discharge flow path in a second direction, opposite to the first direction along the flow axis. Air enters the air handling system through an inlet port and is discharged via an discharge port. The inlet channel is provided with acoustical buffering to attenuate inlet noise. The discharge channel is also provided with acoustical buffering in the form of a discharge silencer to attenuate noise in the discharge channel. An acoustical inlet plenum couples the inlet channel to the discharge channel. The cross-sectional area of the discharge channel adjacent the discharge port is larger than the cross-sectional area of the discharge channel adjacent the acoustical inlet plenum. If the inlet ports are not substantially equally distributed about the air handling system, a transfer passage can be provided between the inlet ports and the inlet channel to provide equalization of the air flow.
