Patent number: 11774130Abstract: A controller for an economizer that provides outdoor air to a conditioned space. The controller includes an error calculator configured determine an indoor air quality (IAQ) setpoint error based on an actual IAQ and an IAQ setpoint, an outdoor air flow (OAF) setpoint adjuster configured to determine an adjusted OAF setpoint based on at least one of the IAQ setpoint error, an initial OAF setpoint, and an OAF setpoint upper limit, and a proportional variable deadband controller (PVDC) configured to adjust an operational deadband of the economizer and adjust an operation of at least one of an actuator and a damper of the economizer to achieve the adjusted OAF based on at least one of an actual OAF and the adjusted OAF setpoint. Achieving the adjusted OAF drives the actual IAQ to the IAQ setpoint.Type: GrantFiled: December 14, 2020Date of Patent: October 3, 2023Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Tyler K. Paddock, Christopher R. Amundson, Nathan T. Ostrye

Patent number: 11561018Abstract: Disclosed herein are related to a system, a method, and a non-transitory computer readable medium for controlling a central plant. In one aspect, the system obtains a control envelope for a device controlled by the controller. The control envelope comprises boundaries of a plurality of control regions in a multidimensional operating space for the device. Each control region is enclosed by a corresponding boundary. The system counts a number of times that a ray of the device crosses the boundary of a control region. The system determines whether an operating point of the device is within the control region based on the counted number. The system operates the device according to a predetermined control technique corresponding to the control region, in response to determining that the operating point of the device is within the control region.Type: GrantFiled: February 22, 2019Date of Patent: January 24, 2023Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Tyler K.

Patent number: 10838440Abstract: A controller for a plurality of devices of a building control system that operate in parallel to provide a desired capacity of heating or cooling for a building space includes a capacity identifier configured to identify the desired capacity of heating or cooling for the building space. The controller further includes a combination finder configured to generate a list of combinations of devices that can be energized to provide the desired capacity. The controller further includes a combination filter configured to remove any combinations from the list that do not meet one or more requirements. The controller further includes a combination selector configured to select one of the combinations based on at least one of a runtime and a transition count. The controller further includes a signal generator configured to generate control signals in accordance with the selected combination and operate the plurality of devices using the control signals.Type: GrantFiled: November 28, 2017Date of Patent: November 17, 2020Assignee: Johnson Controls Technology CompanyInventors: Nathan T. Ostrye, Tyler K. Paddock, Aron M. Seiler, Christopher R. Amundson
