ECONOMICS OF ICE STORAGE SYSTEMS IN A UNIVERSITY ENGINEERING BUILDING.

Author(s) : AYRES J. M., LAU H.

Summary

THE ECONOMIC JUSTIFICATION FOR AN OFF-PEAK COOLING SYSTEM FOR A NEW ENGINEERING AND COMPUTER SCIENCE BUILDING AT A CALIFORNIA UNIVERSITY IN LONG BEACH IS PRESENTED. A CONVENTIONAL CHILLED WATER PLANT WITH ELECTRIC CHILLERS AND COOLING TOWER WAS COMPARED TO AN ICE STORAGE SYSTEM WITH SUBMERGED COIL ICE MAKERS, SCREW COMPRESSORS, AND EVAPORATIVE CONDENSER UNDER 2 OPERATING MODES. BY INVESTING $ 314,540 IN THE ICE STORAGE SYSTEM, THE ON-PEAK DEMAND WAS REDUCED BY 251 KILOWATTS AND THE ANNUAL ELECTRIC COST BY $ 16,426. WITH THE $ 50,200 REBATE AVAILABLE FROM THE UTILITY FOR THE REDUCED ON-PEAK DEMAND, THE COST WAS CALCULATED TO BE $ 25,000 LESS THAN THE CONVENTIONAL SYSTEM, AND OVER THE 20-YEAR LIFE OF THE EQUIPMENT, THE UNIVERSITY WILL SAVE $ 221,000.
