Abstract: A cascaded model predictive control system includes an inner controller and an outer controller. The outer controller determines an amount of power to defer from a predicted power usage to optimize a total cost of power usage. A power setpoint is calculated based on a difference between the predicted power usage and the amount of power to defer. The inner controller determines an operating setpoint for building equipment in order to achieve the power setpoint.

Abstract: A system for distributed device management includes a group of devices. Each device in the group of devices communicate with one or more other devices in the group of devices over one or more network channels, and each device in the group of devices includes a processing circuit. The processing circuit of each device in the group of devices manages one or more devices in the group of devices, authorizes a new device to join the group of devices, and synchronizes data with the new device and with one or more devices in the group of devices over the one or more network channels.

Abstract: A heat exchanger of an HVAC system including an inlet header, an outlet header, and tubes configured to extend between the inlet header and the outlet header. The system also includes a first interchangeable refrigerant distributor segment of the inlet header, where the first interchangeable refrigerant distributor segment includes first orifices configured to fluidly couple with the tubes to facilitate distribution of refrigerant from the inlet header to the tubes in a first configuration. The system also includes a second interchangeable refrigerant distributor segment of the inlet header, where the second interchangeable refrigerant distributor segment includes second orifices configured to fluidly couple with the tubes to facilitate distribution of refrigerant from the inlet header to the tubes in a second configuration. The first orifices include a first characteristic of an orifice cross-sectional internal boundary size or shape, and the second orifices include a second characteristic of the orifice cross-sectional internal boundary size or shape different than the first characteristic.

Abstract: An on/off system operates to affect a variable state or condition of a building by switching between an on state and an off state. An extremum-seeking controller operates the on/off system by providing a pulse width modulated (PWM) control signal having a duty cycle to the on/off system. The extremum-seeking controller is configured to generate the PWM control signal by receiving a performance variable as feedback from the on/off system, extracting a gradient of the performance variable with respect to the duty cycle, modulating the duty cycle using an extremum-seeking control technique to determine an optimal value of the duty cycle that drives the gradient toward zero, and generating the PWM control signal such that each period of the PWM control signal has a pulse width proportional to the duty cycle.

Abstract: A building management system (BMS) including device controllers configured to monitor and control one or more heating, ventilation, or air conditioning (HVAC) devices and to store and process time-series data associated with the HVAC devices. The BMS includes a BMS controller that is communicably coupled to the device controllers. The BMS controller is configured to generate and send one or more processing sub-requests to at least one of the device controllers based on a processing request requesting time-series data associated with an HVAC device. The BMS controller is configured to receive one or more processing results from the at least one of the device controllers and join the one or more processing results into a joined result. The BMS controller is configured to provide the joined result to a requesting entity. The device controllers are configured to receive and process processing sub-requests and send results to the BMS controller.

Abstract: The present disclosure relates to a centering system for a heating, ventilation, and/or air conditioning (HVAC) unit to be mounted to a curb. The centering system includes a centering wedge configured to couple to a base rail of the HVAC unit, the base rail having a lateral surface and a base surface along a length of the HVAC unit. The centering wedge includes an angled surface configured to extend between the lateral surface of the base rail and the base surface of the base rail. The angled surface is configured to contact the curb during installation of the HVAC unit to guide the HVAC unit toward a centered position on the curb.

Abstract: Systems and methods for alarm panel analysis include receiving a plurality of alarm events from the respective alarm panels monitoring corresponding buildings. An alarm analysis system may classify the alarm panels by identifying an alarm type for the alarm events. The alarm analysis system may determine a number of occurrences of each alarm type for the alarm panels, and generate a data point for a dataset for the alarm panels. The alarm analysis system may identify statistical dividers in the data points for the data set, which may be used for assigning a ranking for the alarm panels based on their location in relation to the statistical dividers. The alarm analysis system may construct and a monitoring dashboard which includes the rankings of the alarm panels, which may be rendered on a display to an end user.
