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 control unit is communicatively coupled to multiple variable frequency drives. The control unit includes a controller, and each variable frequency drive may have a respective controller. The controller of the control unit may be communicatively coupled to each variable frequency drive controller and manage and/or configure the multiple variable frequency drives by sending instructions and/or receiving information from the variable frequency drive controllers. In some embodiments, the control unit may be implemented as a part of a mobile computing device, such that the controller may wirelessly and communicatively couple to each variable frequency drive controller. In this manner, managing or changing settings and/or control parameters of multiple variable frequency drives may be performed via a single control unit, avoiding the tedious, repetitive, and inefficient process of using multiple control units.

Abstract: A multiple circuit refrigerant system includes a first refrigerant circuit having a first condenser and a first compressor. The first compressor is an intermediate discharge valve (IDV) compressor. The multiple circuit refrigerant system also includes a second refrigerant circuit having a second condenser and a second compressor. The second condenser is disposed downstream of the first condenser relative to an air flow directed across the first condenser and the second condenser.

Abstract: The present disclosure relates to a heat exchanger including a tube having a length, and a cross-sectional geometry defined by an inner boundary and an outer boundary extending along the length. The tube is configured to flow a refrigerant fluid within the inner boundary to transfer heat. The cross-sectional geometry varies at respective transition points along the length of the tube. The tube is seamless and undeformed at the transition points.
