摘要
数据中心湖水冷却系统是一种高效利用自然冷源的方式,但产生的温排水会影响收纳水体的水环境。为了获取东江湖数据中心实际工况下温排水在河道中的温度扩散规律,使用Fluent对温排水的温度场进行数值模拟。结果表明,受温度影响的范围主要由河流流速决定,河流流速越大,则范围面积越小,影响区域主要集中在排放口附近及河岸附近下游水域。不同月份的平均温升都低于1℃/m2,满足规范要求。
Data center water cooling system is one of the methods to use natural cold source efficiently,but the resulting warm drainage can affect the water environment.In order to obtain the temperature diffusion law of the temperature drainage in the river under the actual working condition of the Dongjianghu data center,the temperature field of the warm drainage is numerically simulated by Fluent.The results shows that the influence range of temperature are mainly affected by the river velocity.When the velocity is higher,the range will be smaller.The affected area is mainly around the discharge outlet and the downstream water near the river bank,and the average temperature rise in different months is lower than 1℃/m2,which meets the requirements of the specification.
