Abstract: Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes an enclosure and an evaporator coil disposed within the enclosure. The HVAC system also includes a pivot member coupled between an edge portion of the evaporator coil and the enclosure. The pivot member is configured to enable the evaporator coil to pivot relative to the enclosure to adjust an operating angle of the evaporator coil during operation of the HVAC system. Additionally, the HVAC system includes an actuator configured to enable pivoting of the evaporator coil to a target operating angle based on an operating parameter input.
