基于Trnsys的某数据中心能耗分析

Energy Analysis of Data Center based of Trnsys

本文以某数据中心为模拟仿真对象,利用Trnsys软件建立了冷却系统中的冷水机组、冷却塔、冷冻泵、冷却泵、湖水泵、板式换热器等模块,对数据中心三种不同运行模式的能耗进行仿真模拟。结果表明:利用湖水进行自然冷却的数据中心能源利用效率为1.23。在采用湖水源作为自然冷源的情况下,相比于传统的机械制冷和冷却塔供冷,该数据中心的能耗分别减少了38.6%和34.7%。

This research is based on an actual data center, and Trnsys is applied to simulate chillers, cooling towers,refrigeration pumps, cooling pumps, lake pumps and plate heat exchangers. Three different operation modes of the energy consumption are simulated and analyzed. The results show that, the PUE of the lake water natural cooling system is 1.23;while using the lake water source as the cooling energy source, compare to the situations of using the traditional mechanical refrigeration system and cooling tower cooling system, the energy effectiveness of the traditional data center decreases 38.6% and 34.7% respectively.
