The optimal supervisory control strategy for a central chilled water facility has been determined. A quadratic linear regression relation for the total system power in terms of the controlled and uncontrolled variables was developed using simulated data. The supply air, chilled water, and condenser water temperatures that minimize energy consumption are determined as functions of load, ambient wet bulb temperature, and sensible heat ratio. The use of the quadratic expression to ine optimal control is demonstrated.
