    Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system that has a first circuit and a second circuit that each have a compressor and a condenser, a conduit extending from the second circuit downstream of the condenser to the first circuit upstream of the compressor, a valve along the conduit that may manage flow therethrough, and a controller that may operate the HVAC system in a first mode such that each circuit separately circulates the refrigerant in each circuit and transition to a second mode such that refrigerant-sharing occurs between the circuits. In response to a request to transition from the second mode to the first mode, the controller may determine an amount of refrigerant subcooling, compare the amount to a threshold value associated with the first mode, and instruct opening of the valve upon a determination that the amount is less than the threshold value.

    Abstract: 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.

    Abstract: A heater assembly for a heating, ventilation, and/or air conditioning (HVAC) system has a heater and a controller enclosure. The heater has a plurality of heating elements in a frame that has two opposing ends. The controller enclosure has two end walls and a plurality of side walls in a non-rectangular polygonal configuration. One of the two opposing ends of the frame is coupled to one of the two end walls such that an orientation of the heating elements may be changed based on respective locations of the plurality of side walls of the controller enclosure.
