Summary

A mathematical programming approach is presented for determining which available chiller plant equipment to use to meet a cooling load and best operating temperatures for the water flows throughout the system. First, a mixed-integer, nonlinear formulation of the problem is developed. A heuristic approach for handling the integer variables is then presented which allows very good solutions to be obtained by solving a series of continuous problems using sequential quadratic programming. Finally, regression analysis of a large number of optimizations are presented which show a linear trend that can be used to help guide the chilled water control system to make long term control decisions.
