摘　　要：随着信息技术的不断进步,提供传递、计算、储存信息等IT服务的数据中心发展迅速。由于数据中心的高能耗特征,其能耗控制对降低数据中心碳排放十分重要。选取上海某水冷冷却架构的数据中心为研究对象,提出其末端送风温度和风机功率依据机房负载率进行调控的节能控制策略,从而避免机房的过度制冷和能源浪费等现象的发生。利用计算流体力学方法对测试机房进行数值模拟,研究不同负载率条件下改变送风温度和送风量对机房热环境的影响,并进行末端节能控制优化研究。结果表明:在不同负载率条件下,将送风温度从20℃提升至22℃,将风机送风风量比例降低20%~50%,机房热环境仍在温度控制要求内保持稳定。通过数值模拟研究获得了数据中心机房的送风温度和风量在不同负载率条件下对机房热环境影响情况,可为数据中心末端节能控制优化提供理论基础,也为数据中心进一步降低PUE等能耗指标提供了参考。With the continuous progress of information technology,data centers that provide IT services such as transmission,computing and storage of information are developing rapidly.Due to the high energy consumption characteristics of data centers,their energy consumption control is very important to reduce carbon emissions.In this paper,the numerical simulation of the test room is carried out by using the computational fluid dynamics method to study the effect of changing the air supply temperature and air supply volume on the thermal environment of a data center with water cooling system in Shanghai under different load rate conditions,and the optimization study of the end energy saving control is carried out.The results show that by increasing the air supply temperature from 20℃to 22℃and reducing the fan air volume by 20%~25%under different load rate conditions,the thermal environment of the server room remains stable within the temperature control requirements.
