An intake hood system for a heating, ventilation, and/or air conditioning (HVAC) unit includes an intake hood having an inlet configured to receive an air flow into the intake hood, a first support configured to engage a first end of an air filter, and a second support configured to engage a second end of the air filter, where the first support is configured to align with a boundary of the inlet. The intake hood system also includes a lock bar configured to couple to the intake hood while abutting the first support and the second support to secure the air filter within the intake hood.

Intake hood system for an HVAC unit

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.

HVAC system with baffles

A heating, ventilation, and air conditioning (HVAC) unit includes a blower support frame and a condensate drain panel assembly. The blower support frame is configured to support one or more blowers of the HVAC unit. The condensate drain panel assembly includes a first condensate drain panel coupled to the blower support frame at a first angle relative to horizontal, a second condensate drain panel coupled to the blower support frame at a second angle relative to horizontal, and a cover panel. The condensate drain panel assembly is configured to direct condensate away from the blower support frame and towards a main condensate drain pan.

Embodiments of the present disclosure are therefore directed toward a condenser section that is configured to draw an air flow into the condenser section, a control section configured to enclose electrical components, and a partition extending between the condenser section and the control section. The partition may include a first air passage and a second air passage formed therein, where the first air passage is configured to enable a portion of the air flow to flow from the condenser section into the control section to cool the electrical components and the second air passage enables the portion of air flow to from the control section to the condenser section.

System and method of cooling of heat generating units in an HVAC unit

A partition wall for a heating, ventilation, and air conditioning (HVAC) system includes a frame defining a perimeter of the partition wall, and one or more panels extending within the frame. Each of the one or more panels comprises a flange configured to abut another of the one or more panels or the frame to provide a substantially air-tight engagement there between.

Partition wall for an HVAC device

The present disclosure relates to a heating, ventilating, and air conditioning (HVAC) unit configured to supply conditioned air to a conditioned space. The HVAC unit includes a first exhaust fan capable of operating at variable speeds and a second constant-speed fan. The HVAC unit also includes a controller configured to determine a target airflow to be provided to the conditioned space, cause actuation of the first exhaust fan at a variable fan speed when the target airflow is greater than zero, and cause actuation of the second exhaust fan when the target airflow is greater than an airflow threshold.

HVAC unit fan control systems and methods

A heating unit for a heating, ventilation and/or air conditioning (HVAC) system may have a first airflow path through the heating unit, a second airflow path through the heating unit, and a heater assembly having a first heating coil positioned within the first airflow path, a second heating coil positioned within the second airflow path, and a coil divider separating the first heating coil and the second heating coil.

Heating unit with a partition

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.

Systems and methods for reheat control of an HVAC system

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.

HVAC fan housing systems and methods

A wall panel assembly for a heating, ventilation, and air conditioning (HVAC) unit includes a panel having a main body, where the panel is configured to be fastened to a frame of the HVAC unit, and a plurality of stiffeners attached to the panel along a perimeter of the main body. A stiffener of the plurality of stiffeners includes a flat portion and a raised portion offset from the flat portion, where the raised portion is configured to sealingly engage with a component disposed within the HVAC unit.
