THERMAL STORAGE RETROFIT RESTORES DUAL TEMPERATURE SYSTEM.

Author(s) : HOLNESS G. V. R.

Summary

THE INTEGRATION OF THERMAL STORAGE INTO THE EXISTING DUAL-TEMPERATURE HEATING AND COOLING SYSTEM ALLOWED IT TO MEET THE REQUIREMENTS OF THE EXPANDED INDUSTRIAL MANUFACTURING FACILITY WHILE AT THE SAME TIME RESTORING THE SYSTEM'S PERFORMANCE. THE EXISTING 17,600 KILOWATT REFRIGERATION PLANT INSTALLED INCLUDED TWO 3,000 KILOWATT STEAM TURBINE CENTRIFUGAL CHILLERS PIGGY-BACKED ON TWO 5,000 KILOWATT ABSORPTION CHILLERS. THE DEMANDS FOR A 7,000 KILOWATT INCREASE IN CAPACITY COUPLED WITH THE NEED FOR CLOSE ENVIRONMENTAL CONTROL RESULTED IN A REQUIREMENT FOR TOTAL RETROFIT OF THE SYSTEM. CAPITAL COST OF THE INSTALLATION WAS WITHIN 5% OF INITIAL ESTIMATES. HOWEVER, ACTUAL INSTALLED COST INCREASED BYA FURTHER 8% DUE TO FIELD CONDITIONS. THE THERMAL STORAGE SYSTEM ITSELF WENT IN WITHOUT ANY SIGNIFICANT PROBLEMS, THE MOST PREVALENT PROBLEMS BEING CALIBRATION AND SENSITIVITY OF MONITORING INSTRUMENTATION. THERMAL STORAGE CAN BE JUSTIFIED E, IT OFFERS THE BENEFITS OF INCREASED PLANT OPERATIONAL STABILITY AND RELIABILITY AND REDUCED OPERATING COSTS THROUGH SAVINGS IN UTILITY DEMAND CHARGES.
