Energy performance evaluation of set point control and near optimal control for cooling towers used in water chilling systems.

Author(s) : SAULLES T. de, PEARSON C. C.

Summary

Optimization of the condenser side control in chiller systems incorporating cooling towers can achieve significant energy savings. The paper compares the theoretical savings that can be achieved at a large chiller station through the implementation of two optimization techniques. One involves simply lowering the condenser water design set point to a value which is more efficient under the load conditions that are experienced for the majority of the year. The other more involved technique uses a control algorithm to regulate the cooling tower fan speed in response to the cooling load.
