Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes an air flow amplifier coupled to a fan deck of the HVAC unit. The air flow amplifier includes a ring having an annular cavity and an air flow inlet formed in the ring. The air flow inlet is configured to direct an air flow into the annular cavity. The air flow amplifier also includes a first annular air flow outlet formed in the ring and configured to direct a first portion of the air flow out of the annular cavity and along an inner diameter of the ring. The air flow amplifier further includes a second annular air flow outlet formed in the ring and configured to direct a second portion of the air flow out of the annular cavity and along the inner diameter of the ring.

Abstract: A blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a centrifugal fan having a fan wheel. A plurality of blades are coupled to the fan wheel at an inner blade boundary and extend radially to an outer blade boundary. The blower assembly includes a first housing panel and a second housing panel disposed on opposite sides of the centrifugal fan and extending transverse to the centrifugal fan. The blower assembly includes a wall extending between the first housing panel and the second housing panel and a flange extending from the wall at a vertex. The flange extends outwardly from the wall. A first radial distance from the vertex to the outer blade boundary is between 4 percent and 20 percent of a second radial distance from a rotational axis of the centrifugal fan to the outer blade boundary.
