Paper Abstract:	In this paper, we apply the data envelopment analysis to evaluate the operation strategy of chillers of air-conditioning by the innovated method which builds the performance index of chiller efficiency according to pure technology efficiency of data envelopment analysis with factors of chiller load capacity and outside air wet bulb temperature. The study will analyze the chiller operation based on the real case of high tech factory, and the result leads to the power consumption of chillers with high pure technology efficiency is less than it with the low pure technology efficiency. Furthermore, this paper proves the innovated index, pure technology efficiency, can use to present the energy efficiency of chillers.
