Abstract: A desuperheater of a heating, ventilation, and/or air conditioning (HVAC) system includes a first conduit defining a first fluid flow path configured to receive a refrigerant, and a second conduit defining a second fluid flow path and configured to facilitate heat transfer between the first fluid flow path and the second fluid flow path. The desuperheater also includes an inlet of the second conduit configured to receive collected water into the second fluid flow path. The desuperheater also includes a ventilation hole disposed in the second conduit and configured to vent water vapor from the second fluid flow path.

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/or air conditioning (HVAC) system includes a reversible valve having an outlet configured to direct refrigerant to a reheat heat exchanger of the HVAC system. The reversible valve is further configured to be in a first configuration to direct the refrigerant through a refrigerant circuit in a first flow direction in a heating mode of the HVAC system and to be in a second configuration to direct the refrigerant through the refrigerant circuit in a second flow direction in a cooling mode of the HVAC system.
