For economic evaluation of cooling plant equipment in the preliminary design stage, it is necessary to simplify energy prediction method, which should include the efficiency corrected by part-load ratio. This study proposed a simplified correlation method with regression equations of time-average partial loads and chiller capacity. DOE-2 program was used to carry out a parametric study of twelve variables. Five input variables were considered to be significant and were used in the regression equations. To test the accuracy of this method, calculated results were compared with DOE-2 simulated results. Testing showed good agreement between these two results with 5.9-7.6% error. It is hoped that this method can be used as an easy prediction tool for comparing energy use of different cooling plants during the early design stage.
