Abstract

冷却系统是数据中心的关键组成部分，负责为IT服务器的运行持续维持适宜的温度与相对湿度，而冷却系统在数据中心用电中占据相当大的比重。本文综述了数据中心的各类冷却系统：超高效露点冷却机凭借创新的结构设计，是能效最高的冷却系统之一；本研究分析了露点冷却系统的创新结构、冷却原理及其面临的主要挑战。本研究考察了位于温暖湿润地区的GK大学一座在运数据中心。该数据中心目前采用传统蒸气压缩风冷系统为IT服务器降温，分析表明，该冷却系统因能耗高，电能利用效率（PUE）达1.87。针对这一问题，本研究以模拟的超高效露点冷却系统替代蒸气压缩风冷系统，采用最小二乘法与套索回归（Lasso Regression）建立了露点冷却系统的数学模型，并通过交叉验证确认了模型的有效性。模型预测的产品空气温度表明，其效率显著高于传统冷却系统。为克服冷却能力潜力受限的问题，本文模拟引入一台民用除湿机作为辅助部件；该除湿机以极低的能耗有效提升了露点冷却系统的性能，使PUE显著降低。
