Abstract: Disclosed herein are related to a system, a method, and a non-transitory computer readable storing instructions for operating an energy plant comprised of heating, ventilation and air conditioning (HVAC) devices. In one aspect, the system generates gradient data indicating a gradient of operating performance of the energy plant with respect to values of a plurality of control variables of HVAC devices. The system determines, from the plurality of control variables, a reduced group of control variables of the HVAC devices based on the gradient data. The system determines a set of values of the reduced group of control variables. The system operates the energy plant according to the determined set of values of the reduced group of control variables.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes an expansion device disposed between a condenser and an evaporator of a vapor compression system and a control panel communicatively coupled to the expansion device. The control panel is configured to: determine a liquid refrigerant level set point of the condenser based on parameters of the vapor compression system, provide a first control signal to increase an opening of the expansion device in response determining that the current liquid refrigerant level in the condenser is greater than a determined liquid refrigerant level set point of the condenser, and provide a second control signal to decrease the opening of the expansion device in response to determining that the current liquid refrigerant level in the condenser is less than the determined liquid refrigerant level set point of the condenser.

Abstract: A building management system (BMS) for heating, ventilation, or air conditioning (HVAC) parameters in a building. The BMS includes one or more processing circuits including one or more memory devices coupled to one or more processors. The one or more processors query a training data storage and receive training data, institute a policy with a machine learning engine and train the policy using the training data, receive temperature, pressure, and humidity (TPH) sensor data from one or more sensors, determine a fault based on the TPH sensor data, provide the TPH sensor data and the fault to the policy of the machine learning engine and output a corrective action to resolve the fault, and generate a work order for a user based on the TPH sensor data, the determined fault and the corrective action.

Abstract: Systems and methods for distributing load of an energy plant are disclosed herein. A target load of at least a first device and a second device of the energy plant is obtained. A first power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a first combination of set points to satisfy the target load is predicted. A second power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a second combination of set points to satisfy the target load is predicted. The first power consumption and the second power consumption are compared, and a combination of set points rendering lower power consumption is selected to operate the energy plant.

Abstract: The present disclosure relates to a climate management system having an outdoor coil of a refrigerant circuit, a first indoor coil of the refrigerant circuit, and a second indoor coil of the refrigerant circuit disposed downstream of the first indoor coil with respect to a flow of air directed across the first indoor coil and the second indoor coil. The climate management system is configured to, in a cooling mode, direct refrigerant flow in a first direction through the outdoor coil, direct refrigerant flow through the first indoor coil, and restrict refrigerant flow from the second indoor coil. The climate management system is also configured to, in a heating mode, direct refrigerant flow in a second direction through the outdoor coil, direct refrigerant flow through the second indoor coil, and restrict refrigerant flow from the first indoor coil. The second direction is opposite the first direction.

Abstract: A residential HVAC system includes, a compressor, and an outdoor unit controller in communication with the compressor. The outdoor unit controller is configured to receive an indoor ambient temperature and a temperature set point. The outdoor unit controller is further configured to determine an outdoor ambient temperature, and to determine an operating value for the compressor based on a percentage of a delta between a minimum operating value of the compressor and a maximum operating value of the compressor, plus the minimum operating value. The minimum operating value and the maximum operating value are based on the determined outdoor ambient temperature. The percentage of the delta is based on a predefined temperature differential multiplier and one or more time dependent multipliers. The outdoor unit controller is further configured to modify the current operating value of the compressor with the determined operating value.
