Abstract：
Presents the concept, principle and system forms of chilled water system for data centers, and analyses the relative energy saving property of part-free cooling system. Taking the typical climate conditions of Shanghai, Beijing and Hohhot as analysis data, studies the relative energy saving advantage of different chilled water supply and return temperature in the part-free cooling system.
