THE SIMULATION AND PERFORMANCE OF A CENTRIFUGAL CHILLER.

Summary

THE MODEL IS BASED ON A HEAT PUMP THERMODYNAMIC CYCLE AND EMPIRICAL CORRELATIONS FOR THE PERFORMANCE OF THE SYSTEM COMPONENTS. THE SYSTEM SIMULATED IS COMPOSED OF A VARIABLE-SPEED CENTRIFUGAL COMPRESSOR WITH A HOT-GAS BYPASS OPTION FOR CAPACITY CONTROL, TWO SHELL-AND-TUBE HEAT EXCHANGERS, AND AN EXPANSION DEVICE. THE MODEL WAS VALIDATED AND CALIBRATED AGAINST EXPERIMENTAL TEST RESULTS. THE PERFORMANCE OF A SIMILAR CHILLER SYSTEM AT VARIOUS OPERATING CONDITIONS AND DESIGN MODIFICATIONS WAS ANALYZED. IT WAS FOUND THAT SIGNIFICANT PERFORMANCE IMPROVEMENT CAN BE REALIZED BY USING VARIABLE-SPEED DRIVE AND AN ON-DEMAND CONTROL STRATEGY.
