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.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a cabinet defining a cabinet interior configured to house components of the HVAC unit. The cabinet includes an opening defining an air flow path between the cabinet interior and an external environment. The HVAC unit also includes a fan assembly including fan blades configured to move an air flow through the opening, wherein the fan assembly is configured to enable translation of the fan blades through the opening between a shipping arrangement in which the fan blades are disposed in the cabinet interior and an operational arrangement in which the fan blades are disposed in the external environment.

Abstract: A furnace for a heating, ventilation, and/or air conditioning (HVAC) system includes a heat exchanger tube including a tube inlet and a tube outlet, such that the heat exchanger tube is configured to receive combustion products via the tube inlet, circulate the combustion products through the heat exchanger tube, and discharge the combustion products via the tube outlet. Additionally, the furnace includes a collector box coupled to the heat exchanger tube and having a cavity configured to receive the combustion products via the tube outlet. The furnace includes a diverter plate disposed within the cavity, where the diverter plate overlaps the tube outlet to disperse the combustion products received via the tube outlet throughout the collector box.

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.
