间接蒸发冷却冷水机组在我国数据中心的应用分析
Application analysis of indirect evaporative cooling water chillers in data centers in China
摘要：
以既有数据中心为模型，选取20个位于不同地区的典型城市作为样本，比较了不同地区应用间接蒸发冷却冷水系统和水冷冷水机组空调系统的运行状况。通过计算2种冷源系统的PUE及空调系统全年耗电量，分析了间接蒸发冷却冷水系统在不同地区的节能规律及其相较于传统水冷冷水机组空调系统的节能潜力和经济优势，给出了间接蒸发冷却冷水机组适合在我国推广的地区，为不同地区数据中心冷源系统的选择提供参考。
Abstract：
Taking the existing data center as a model, 20 typical cities in different regions are selected as samples to compare the operation conditions of indirect evaporative cooling water systems and water-cooled chiller air conditioning systems in this paper. By calculating the PUE of two kinds of cold source systems and the annual power consumption of the air conditioning system, this paper analyses the energy saving law of the indirect evaporative cooling water system in different regions and its energy saving potential and economic advantages compared with the traditional water-cooled chiller air conditioning system，and gives the regions where indirect evaporative cooling water chillers are suitable for promotion in China, which provides references for the selection of data center cold source systems in different regions.
