中文摘要：
本文针对我国不同气候区的气候特点,以某中等规模数据中心为例,对风冷式直接蒸发系统和水冷式冷水机组系统两种常用的数据中心制冷系统进行了能效分析,量化给出了季节性和区域性气候差异对数据中心制冷系统的能效影响,分析了风冷式和水冷式系统在不同气候区的应用优势。对一种将热管循环与蒸气压缩制冷循环相结合的复合型自然冷源系统进行了运行测试,计算给出了不同气候区自然冷源的可用时间和节能潜力,分析结果可用于数据中心选址以及其制冷系统的优化设计。
英文摘要：
This paper analyzed the energy efficiency of two commonly used cooling systems （including the air-cooled type and the water-cooled type） in data centers according the climatic characteristics of different climate zones based on the energy consumption measuring results of a medium size data center. The results revealed the influence of the seasonal and regional climate differences on the performance of the data center cooling systems and also showed the application advantages of the air-cooled and water-cooled systems. An operation test on a free cooling system combining the heat pipe cycle and the vapor compression cycle was conducted. The results concluded the available time and energy saving potential of the combined system in different climate zones, which can be used in the site selection of data centers and the optimization of the data center cooling systems.
