摘要
高能耗建筑数据中心的主要耗能部分是服务器和空调系统。降低服务器与空调系统的能耗可以有效地降低数据中心的总能耗。机房的环境温度对服务器与空调系统能耗有较大影响,因此合理地控制机房环境温度可以达到降低数据中心总能耗的目的。以西安市某数据中心为研究对象,通过建筑能耗模拟软件EnergyPlus分析机房内环境温度对服务器能耗、空调系统能耗及总能耗的影响。并在此基础上,选择不同气候区城市哈尔滨、上海、广州进行对比模拟分析。结果表明:随着机房环境温度设定值的升高,服务器能耗呈现升高趋势,空调系统能耗呈现下降趋势,总能耗先降低后升高,但是不同地区总能耗最低时对应的机房环境温度设定值不同。
The main energy consumption of high-energy consuming building data centers is from server and HVAC. Reducing the energy consumption of server and HVAC can effectively lower the total energy consumption of the data center. The ambient temperature of the computer room has a great influence on the energy consumption of the server and HVAC. Therefore,reasonable control of the ambient temperature of the computer room is crucial. Taking a data center in Xi ’an as the research object, the energy consumption of the server room, the HVAC, and the total energy consumption were analyzed by EnergyPlus. On this basis,cities including Harbin,Shanghai and G uangzhou in different climate regions were selected for comparative simulation analysis. The results show that,following the increase of the ambient temperature set value in the computer room,the energy consumption of the server is rising and the energy consumption of the HVAC is declining. The total energy consumption shows a trend of decreasing first and increasing later,but when the total energy consumption are at the lowest level in different regions,the corresponding ambient temperature set values of the computer room are different.
