数据中心自然冷源利用研究

Study of Free Cooling Utilization in Data Center

数据中心是集中摆放IT设备的特殊建筑,由于IT设备的运行发热量大,需要全年对数据中心进行温度和湿度控制,导致数据中心运行能耗高,其中空调系统用能比例高是数据中心能耗居高不下的主要原因。利用自然冷源能有效降低数据中心空调系统能耗,节能效果显著。本文对三种不同形式的自然冷源利用形式进行分析和比较,给出了不同形式自然冷源的应用范围。

Data center is a kind of special building to place IT equipment.Due to the large heat generation of IT equipment,the temperature and humidity needs to be controlled for the whole year,which leading to high energy consumption.And the high energy consumption percentage of air conditioning system is the main reason of high energy consumption of data center.Free cooling can effectively reduce the energy consumption of data center and the energy saving effect is remarkable.In this paper,three different kinds of natural cold sources are analyzed and compared,and the application scope of different natural cold sources is given.
