Application analysis of indirect evaporative cooling water chillers in data centers in China

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.
