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.
