NEAR-OPTIMAL CONTROL OF COOLING FOR CHILLED-WATER SYSTEMS.

Summary

THE PAPER PRESENTS AN ALGORITHM FOR NEAR-OPTIMAL CONTROL OF COOLING TOWERS. THE ALGORITHM IS BASED UPON AN OPEN-LOOP CONTROL EQUATIONIN TERMS OF THE TOTAL CHILLED-WATER COOLING LOAD. 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. RESULTS OF THE NEAR-OPTIMAL CONTROL ALGORITHM ARE COMPARED WITH THE < TRUE > OPTIMAL SOLUTION APPLIED TO A DETAILED SIMULATION MODEL. THE ALGORITHM IS EXTREMELY SIMPLE AND IS EASILY IMPLEMENTED IN EXISTING SYSTEMS.
