Abstract: The present disclosure relates to an energy recovery wheel for a heating, ventilation, and/or air conditioning (HVAC) system. The energy recovery wheel includes a frame positioned within a passage of the HVAC system. The frame is configured to rotate about an axis of the passage relative to the HVAC system and includes an opening that is configured to transmit an air flow. The energy recovery wheel also includes a heat transfer element coupled to the frame and positioned within the opening, where the heat transfer element is permeable and configured to transition between a closed orientation to occlude the opening and direct the air flow across the heat transfer element and an open orientation to substantially unblock the opening and mitigate interaction between the air flow and the heat transfer element.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit may include a supply fan section having a supply fan disposed therein to force a supply air flow through a discharge plenum of the HVAC unit. The HVAC unit may also include an economizer positioned adjacent the supply fan section to receive an outdoor air flow and direct the outdoor air flow into the supply fan section.

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.
