Description

Presents an algorithm for near-optimal control of cooling towers. It is based on on open-loop control equation in terms of the total chilled-water cooling load. States that the parameters of this equation may be estimated from design data with relations derived from a simple model for cooling tower and chiller power trade-offs with tower control. Compares results of the near-optimal control algorithm with the ‘true’ optimal solution applied to a detailed simulation model. States the algorithm is extremely simple and is easily implemented in existing systems.

KEYWORDS: Algorithms, controls, cooling towers, optimum, comparing.
