Abstract：
According to the energy consumption characteristics of data centers, analyses the influencing factors of cooling tower cooling technology. By establishing a model, analyses the comprehensive coefficient of performance of chilled water system (WSCOP) under various operating conditions. Based on the annual outdoor air design conditions in Beijing, Shanghai and Guangzhou, calculates the annual energy consumption of the chilled water system respectively, and analyses the operating time and energy saving effect of the cooling tower cooling technology.
