Abstract: An energy recovery wheel includes a frame positioned within a passage of a heating, ventilation, and/or air conditioning (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 air conditioning (HVAC) system includes a reheat valve configured to receive a refrigerant flow and regulate division of the refrigerant flow provided to a reheat coil and a condenser. The HVAC system also includes a condenser fan configured to draw a flow of outdoor air across the condenser and a controller communicatively coupled to the reheat valve and the condenser fan. The controller is configured to monitor a position of the reheat valve and to control operation of the condenser fan based on a correspondence between the position of the reheat valve and a threshold degree of opening.
