Abstract
A method of operating a chiller to avoid future surge events, the method comprises applying chiller operating data associated with a chiller as an input to one or more machine learning models; and generating a threshold for a controllable chiller variable to prevent a future chiller surge event from occurring based on an output of the one or more machine learning models, further comprising affecting operation of the chiller based on the threshold to prevent the future chiller surge event from occurring. The method enables automatic control of a chiller to avoid future chiller surge events.
Claims20
A system, comprising:
- processing circuitry;
- and
- memory storing instructions thereon that, when executed by the processing circuitry, cause the processing circuitry to:
- generate a boundary for a value of a controllable chiller variable to prevent a future chiller surge event from occurring based on a probability that the future chiller surge event will occur if the value of the controllable chiller variable is used to operate a chiller, wherein the instructions, when executed by the processing circuitry, cause the processing circuitry to:
- compare the probability that the future chiller surge event will occur with a probability threshold;
- and
- set the value of the controllable chiller variable as the boundary for the controllable chiller variable in response to a determination that the probability that the future chiller surge event will occur does not violate the probability threshold;
- and
- affect operation of the chiller based on the boundary to prevent the future chiller surge event from occurring.
A controller configured to control operation of a chiller, wherein the controller comprises:
- a memory comprising instructions stored thereon, wherein the instructions, when executed by one or more processors, cause the controller to:
- determine a probability that a future chiller surge event will occur if a value of a controllable chiller variable is used to operate the chiller;
- compare the probability that the future chiller surge event will occur with a probability threshold;
- set the value of the controllable chiller variable as a boundary for the controllable chiller variable in response to a determination that the probability that the future chiller surge event will occur does not violate the probability threshold;
- and
- affect operation of the chiller based on the boundary to prevent the future chiller surge event from occurring.
A system, comprising:
- processing circuitry;
- and
- memory storing instructions thereon that, when executed by the processing circuitry, cause the processing circuitry to:
- determine an upper boundary, a lower boundary, or both for a value of a controllable chiller variable to prevent a future chiller surge event from occurring based on a probability that the future chiller surge event will occur if the value of the controllable chiller variable is used to operate a chiller, wherein the instructions, when executed by the processing circuitry, cause the processing circuitry to:
- compare the probability that the future chiller surge event will occur with a probability threshold;
- and
- set the value of the controllable chiller variable as the upper boundary or the lower boundary for the controllable chiller variable in response to a determination that the probability that the future chiller surge event will occur does not violate the probability threshold;
- and
- affect operation of the chiller based on the upper boundary or the lower boundary.
