Numerical models for air- and water-cooled centrifugal, reciprocating and screw chillers are presented. The models were established by curve-fitting manufacturers' chiller performance data. A simulation study aimed at comparing the performance of alternative chiller number-size combinations for a building is described. This shows that such studies should be based on realistic rated COP values for chillers, as they will strongly influence the predicted electricity consumption and thus the conclusion on which combination is to be adopted.
