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.

Abstract: A furnace for a heating, ventilation, and/or air conditioning (HVAC) system includes a first set of heat exchanger tubes positioned within an air flow path of the furnace through which an air flow may be directed, a second set of heat exchanger tubes positioned within the air flow path of the furnace, and a deflector baffle positioned within the air flow path and configured to direct a portion of the air flow toward the second set of heat exchanger tubes. The first set of heat exchanger tubes, the deflector baffle, and the second set of heat exchanger tubes are each respectively offset from one another in a direction of the air flow along the air flow path.

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 centering system for a heating, ventilation, and/or air conditioning (HVAC) unit to be mounted to a curb. The centering system includes a centering wedge configured to couple to a base rail of the HVAC unit, the base rail having a lateral surface and a base surface along a length of the HVAC unit. The centering wedge includes an angled surface configured to extend between the lateral surface of the base rail and the base surface of the base rail. The angled surface is configured to contact the curb during installation of the HVAC unit to guide the HVAC unit toward a centered position on the curb.
