Summary

THE AUTHORS TOOK A SIMPLE AIR-CONDITIONING SYSTEM USING A SINGLE CHILLER, COOLING TOWER AND CONDENSER WATER PUMP AND, KEEPING TO A DESIGNATED CHILLER AND BUILDING LOAD THEY PROCEEDED TO OPTIMISE THE CONDENSER WATER FLOW, PUMP SIZE, COOLING TOWER AND FAN. THREE CITIES IN THE USA WERE CONSIDERED WITH DIFFERENT ELECTRICITY TARIFFS AND THE OPTIMISED SOLUTIONS WERE COMPARED TO ONE DICTATED BY CONVENTIONAL GUIDELINES. OPTIMISATION METHODS AND FORMULAE ARE QUOTED AND ALTERNATIVES WERE RESTRICTED TO STANDARD PIPE SIZES, AND PUMPS, TOWERS AND FANS TO SINGLE MANUFACTURERS. THE RESULTS SHOWED IN ALL CASES THAT THE OPTIMISED SOLUTION USED LESS CONDENSER WATER THAN CONVENTIONAL AND THE COMBINED OPERATING AND CAPITAL PAYBACK COST WAS CONSIDERABLY REDUCED. D.W.H.
