Abstract
An air handling apparatus for blending outside and return airflow including a housing having exterior side walls, a top and a bottom and containing first and second inlet regions and a mixing chamber. Outside air flows through a first inlet into the first inlet region while return air flows through another inlet into the second inlet region. There are also first and second damper mechanisms positioned between the first and second inlet regions and the mixing chamber, each capable of adjusting the amount of airflow from the respective inlet region to the mixing chamber. An exhaust fan is mounted on the housing above the second inlet region while an air supply fan is mounted in the housing on the downstream side of the mixing chamber. Heating and cooling coil units can be located downstream of the mixing chamber.
