Energy Consumption and Energy Saving Analysis of Air-Conditioning Systems of Data Centers in Typical Cities in China

The energy consumption status and saving potential of the air-conditioning systems data centers in seven typical cities China (Xinjiang, Beijing, Jinan, Shanghai, Nanning, Guilin, Haikou), representing diverse climate regions, were studied. power usage effectiveness (PUE) cooling load factor (CLF) taken as evaluation indicators. First, situations existing analyzed using an internship survey. Second, meteorological throughout year for statistically analyzed. Then, two renovation schemes proposed. operating hours under different modes calculated, PUE evaluated by taking production 15 °C chilled water example. This study provides overall picture utilization current Chinese center market solutions improving design systems, with benefits.
