中国各地区数据中心自然冷却时间分析

Analysis of free cooling hours for data centers in China

通过对2种自然冷却技术进行分析,确定自然冷却切换点,并统计全国各气象站点全年室外逐时气象参数,确定各气象站点2种自然冷却方式的全年完全自然冷却时间。通过空间插值的方法,得到全国各地区2种自然冷却方式的全年自然冷却时间分布图。从分布图上能直观地看出全年2种自然冷却方式在全国各地区的自然冷却时长,从而为数据中心业主和设计师提供选址参考。

Discusses two different kinds of free cooling technologies and figures out the switch points. According to typical annual hourly outdoor air design parameters of each weather station in China, calculates the available hours meeting the required conditions of free cooling. By the interpolation method on spatial analysis, obtains the free cooling hours distribution map of China for different free cooling technologies, which is very useful for site selection of data centers.
