Abstract: A fan shroud for a heating, ventilation, and/or air conditioning (HVAC) unit may include an outer wall to couple to a housing of the HVAC unit and an inner wall disposed within the outer wall. Additionally, the inner wall may be air permeable. The fan shroud may also include an acoustic damping material disposed between the outer wall and the inner wall. The fan shroud may encircle a fan of the HVAC unit to reduce noise.

Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) unit including a condenser coil and a condenser fan assembly. The condenser fan assembly includes a first fan and a second fan, where the first fan and the second fan are each configured to operate to pull air through the condenser coil. The HVAC unit also includes a motor of the first fan including a housing and a shaft, where the motor is configured to operate to rotate the shaft in a first direction. The HVAC unit further includes a unidirectional bearing that is coupled to the shaft and a mounting assembly of the condenser fan assembly, where the unidirectional bearing is configured to block rotation of the shaft in a second direction that is opposite the first direction.

Abstract: The present disclosure relates to a liquid drainage system for a heating, ventilation, and/or air conditioning (HVAC) system, where the liquid drainage system includes a drain pan configured to collect and drain condensate within a housing. The drain pan is configured to be mounted within the housing separate from an evaporator assembly and is removable from the housing independent of the evaporator assembly. The liquid drainage system also includes a drain pan extension plate configured to collect and drain condensate to the drain pan, where the drain pan extension plate is configured be removably mounted within the housing. The drain pan extension plate and the drain pan are configured to overlap with one another, in an assembled configuration, along a direction of airflow across the evaporator assembly.
