Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system including an exhaust plenum configured to receive an exhaust air flow from a cooling load. The HVAC system also includes a condenser configured to receive an input air flow and transfer thermal energy to the input air flow. A panel is positioned directly adjacent to and between the exhaust plenum and the condenser. The panel includes a passage providing a fluid flow path directly between the exhaust plenum and the condenser. The passage is configured to discharge a portion of the exhaust air flow, and the input air flow includes the portion.

Abstract: A fan assembly for a heating, ventilation, and/or air conditioning (HVAC) unit includes a hub having a fan blade extending therefrom. The fan assembly includes a fan pitch adjuster configured to engage the fan blade and to adjust a pitch of the fan blade relative to the hub in response to movement of the fan pitch adjuster relative to the hub. The fan assembly also includes a motor shaft coupled to the fan pitch adjuster and to the hub, where the motor shaft is configured to drive rotation of the fan pitch adjuster and the hub. The fan assembly further includes an actuator coupled to the fan pitch adjuster and configured to axially move the fan pitch adjuster along the motor shaft and relative to the hub to adjust the pitch of the fan blade.
