    摘要: The present disclosure relates to an HVAC system door assembly that includes a door that includes a panel having a first side and a second side opposite the first side, and a first seal circuit. The first seal circuit is disposed on the first side. The HVAC system door assembly also includes a door frame that includes a second seal circuit. HVAC system door assembly further includes a ridge projecting from one of the first seal circuit or the second seal circuit configured to align with and engage a central portion of the other of the first seal circuit or the second seal circuit when the door is in a closed position with respect to the door frame. The ridge includes a cross-sectional profile having a flattened peak section with sloping side sections that extend from boundaries of the flattened peak section to a base of the ridge.

    摘要: 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.

    摘要: A heating, ventilation, and/or air conditioning (HVAC) unit includes a heater housing having a first side wall, a second side wall opposing the first side wall, and a ceiling extending between the first side wall and second side wall. The HVAC unit also includes a first mounting rail disposed across the first side wall at a first distance from the ceiling, and a second mounting rail disposed across the second side wall at a second distance from the ceiling. The first distance is greater than the second distance. The HVAC unit also includes a heating element assembly coupled to the first and second mounting rails and having a planar heating interface extending from the first mounting rail to the second mounting rail.

    摘要: 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.
