 In order to improve the energy efficiency of data center and reduce the system operation PUE, according to the operating characteristics of high sensible heat and low latent heat, adopts indirect evaporative chilled water air conditioning system (with natural cold source) to supply cold for a data center in northern Xinjiang. Adds the ethylene glycol (freezing point temperature is -32 ℃) solution with 45% volume concentration to the air conditioning chilled water system to prevent chilled water freezing and realize the natural cooling mode of the system in winter. The result shows that the PUE is 1.362, which meets the required target, and the energy saving effect is remarkable.
