摘　　要：新型空调水冷系统可充分利用自然冷源,减少数据中心冷水机组的使用,实现降低数据中心电能利用比值(PUE)目标。其技术原理是:将冷冻水温度由7℃提高至15℃并采用间接蒸发冷却的冷水机组制冷取代传统直接蒸发冷却塔,其中间接蒸发冷却的冷水机组可以带来比开式冷却水塔低2℃以下的冷水。同时取一次水供回水温度155℃/21℃的基础条件下,延长了间接蒸发冷却冷水机组自然免费制冷的时长,由此充分利用自然冷源实现冷却功能。Thee new air connditioning waater cooling syystem can maake full use oof natural cold sources,redduce the use of water chillers iin data centerrs,and achieve the goal of reducing the PUE of data centers.The ttechnical prinnciple is that tthe w2intewAemperature off chilled waterr is raised fromm 7℃to 15℃,and the tra℃ditional directt evaporation cooling toweer is replaced bby ndirect evaporration cooling water chiller,,in which the indirect evaporation coolinng water chilleer can bring coold water beloow℃lower thann the open coooling water toower.At the ssame time,unnder the basic condition thaat the temperaature of primaary water supply annd return watter is 15/21℃,the natural ffree cooling tiime of indirecct evaporation cooling chiller is prolongeed,Ksoo that the natuural cold sourcce is fully utiliized to realizee the cooling ffunction.
