Abstract: A heating, ventilation, and/or air conditioning (HVAC) system has a refrigerant circuit that includes a compressor, a condenser system with a first set of tubes and a second set of tubes fluidly separate from the first set of tubes within the condenser system, and a valve positioned downstream of the compressor and upstream of the second set of tubes relative to a direction of refrigerant flow through the refrigerant circuit, in which the refrigerant circuit is configured to direct refrigerant through the first set of tubes and through the second set of tubes. The HVAC system further has a switch configured to detect an operating parameter and to instruct the valve to close based on the operating parameter such that refrigerant flow is blocked through the second set of tubes and refrigerant flow is enabled through the first set of tubes.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a plurality of condenser fans and a control system. The control system is configured to perform operations that include identifying an ambient condition, determining an operating mode of the HVAC system, and operating a subset of the plurality of condenser fans based on the operating mode and in response to identification of a low ambient condition.

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 vapor compression system that includes a baffle that separates a first condenser and a first fan from a second condenser and a second fan. A controller that switches between first and second modes of operation. In the first mode of operation the controller closes a valve to block a flow of a refrigerant through a first condenser and turns off the first fan. In the second mode of operation the controller opens the valve to enable the flow of the refrigerant through the first condenser and turns on the first fan.

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.
