基于热环境评价指标的数据中心水冷空调热环境研究

Research on thermal environment of water-cooled air conditioning in data center based on thermal environment evaluation index

以数据中心水冷空调系统为研究对象,采用CFD软件模拟分析不同回风温度及服务器布局下的冷通道温度场、气流组织等,并选用热环境评价指标进行定量分析。结果表明,机房满负载时最佳回风温度为30℃,此时服务器无间隔的摆放方式热环境评价结果更优,且冷通道中间位置的气流组织较好。

Taking the data center water-cooled air-conditioning system as the research object, using CFD software to simulate and analyze the cold aisle temperature field and air distribution under different return air temperatures and server layouts, and select thermal environment evaluation indicators for quantitative analysis. The results show that the best return air temperature when the computer room is fully loaded is 30 ℃. At this time, the thermal environment evaluation result of the server without spacing is better, and the airflow organization in the middle of the cold aisle is better.
