This paper explains how to enhance the energy performance of a chiller plant designed with chillers ofequal size or unequal size and having superior coefficient of performance (COP) at part load operation.A simulation study was carried out on an air-cooled centrifugal chiller plant serving an office building.Four design options with respect to the number and nominal capacity of chillers were investigated(OP1: 6 x 1124kW; OP2: 8 x 810kW; OP3: 4 x 1213kW + 2 x 810kW; OP4: 2 x 1350kW + 2 x 1107kW +2 x 801kW).
