DEVELOPMENT OF COMPUTERIZED CONTROL STRATEGIES FOR A LARGE CHILLED WATER PLANT.

Author(s) : LAU A. S., BECKMAN W. A., MITCHELL J. W.

Summary

COMPUTER MODELS OF THE CHILLED WATER SYSTEM WERE DEVELOPED TO STUDY THE ENERGY CONSERVATION POTENTIAL OF CONTROL STRATEGIES INTENDED FOR THE MINICOMPUTER CONTROL SYSTEM. EMPIRICAL CURVE FITS WERE USED FOR ALL OF THE COMPONENTS EXCEPT THE COOLING TOWER. AN EFFECTIVENESS MODEL BASED ON MANUFACTURER'S DATA WAS USED FOR THE COOLING TOWER. COMPARISONS OF MODELED PERFORMANCE WITH MEASURED DATA SHOWED GOOD AGREEMENT. OPTIMAL CONTROL STRATEGIES FOR THE NUMBER OF CHILLERS, COOLING TOWER FAN SPEEDS, AND CONDENSER PUMP FLOW RATES WERE DEVELOPED.
