数据中心机房新风送风状态点的分析

Analysis on outdoor supply air state points in data center computer rooms

基于数据中心机房微正压的要求,针对新风系统的能耗控制措施在降低PUE值方面效果显著。新风系统能耗可通过确定系统所需的新风量、准确的新风送风状态点控制。其中,新风送风状态点的选取对新风系统能耗有直接影响。针对数据中心不同通道封闭情况、不同季节的新风处理过程进行了分析,得出了在不同情况下相对合理的机房新风送风状态点,为类似数据中心机房设计提供参考。

Based on the requirement of micro-positive pressure in the computer room of data centers, the energy consumption control measures for the outdoor air system are effective in reducing the PUE value. The energy consumption of outdoor air systems can be controlled by determining the required outdoor air and the accurate outdoor supply air state point. Among them, the selection of the outdoor supply air state point directly impacts on the energy consumption of outdoor air system. According to the closed situation of different channels and different seasons, analyses the outdoor air treatment process in the data center, and obtains the relatively reasonable outdoor supply air state points of the computer room under different conditions, which provides a reference for the computer room design of similar data centers.
