ABSTRACT:
An air-conditioning unit including a centrifugal blower for centrifugally blowing air having a generally horizontal axis a rotation and a scroll having an elongated discharge plenum above the blower and an air guide about the blower for directing air exiting the blower to the discharge plenum through a discharge port having first and second ends. The air guide has a radius from the rotational axis of the fan which increases from a cutoff point near the first end of the discharge port to the second end of the discharge port. The scroll also has a curved air foil located above the blower and to a side of the blower toward the second end of the discharge port. The air foil has a leading edge near the blower and a trailing edge in the discharge plenum effective to divert a portion of air exiting the blower toward the second end of the discharge port to equally distribute air across the discharge plenum. The air foil intersects the discharge port near the lateral center of the discharge port and near the center of the air foil. Preferably, the air-foil is either forwardly curved or double-curved.
