CHILLED-WATER LOOP OPTIMIZATION.

Author(s) : WEPFER W. J., SHELTON S. V.

Summary

THE PAPER DESCRIBES THE OPTIMIZATION OF WATER FLOW RATE FOR A CHILLED-WATER HEAT TRANSFER LOOP AS A FUNCTION OF THE AIR-WATER COIL SIZE AND THE REFRIGERANT-WATER COIL SIZE. THIS PROBLEM HAS BEEN SUCCESSFULLY USED AS A CASE STUDY IN A SENIOR-LEVEL DESIGN CLASS. THE OPTIMIZATION PROBLEM IS FORMULATED IN TERMS OF DIMENSIONLESS VARIABLES. THE RESULTS SHOW THAT FOR EACH POSSIBLE HEAT EXCHANGER SELECTION, A FINITE OPTIMAL FLOW RATE EXISTS, WHICH CORRESPONDS TO A MINIMUM TEMPERATURE DIFFERENCE BETWEEN THE INLET AIR TEMPERATURE AND THE EVAPORATOR TEMPERATURE. THE NONDIMENSIONAL MODEL IS THEN AUGMENTED BY A SPECIFIC SET OF BOUNDARY CONDITIONS WHICH ARE USED TO SELECT THE OPTIMUM DESIGN FOR A SPECIFIC CHILLED-WATER HEAT TRANSFER LOOP.
