Energy saving analysis of a new air conditioning water cooling system
The new air conditioning water cooling system can make full use of natural cold sources,reduce the use of water chillers in data centers,and achieve the goal of reducing the PUE of data centers.The technical principle is that the temperature of chilled water is raised from 7℃ to 15℃,and the traditional direct evaporation cooling tower is replaced by indirect evaporation cooling water chiller,in which the indirect evaporation cooling water chiller can bring cold water below 2 ℃ lower than the open cooling water tower.At the same time,under the basic condition that the temperature of primary water supply and return water is 15/21 ℃,the natural free cooling time of indirect evaporation cooling chiller is prolonged,so that the natural cold source is fully utilized to realize the cooling function.
