空调温度对数据机房总能耗的影响
Influence of air conditioning temperature on total energy consumption of data centers
摘要：
数据中心的高能耗问题成为各方关注的重点。本文针对上海市某数据中心业务包间在不同空调末端送回风设定温度下对空调末端运行能耗、IT设备运行能耗及空调末端能效的影响进行了测试研究。研究发现:随着空调末端送回风温差增大,机房整体运行能耗降低,空调末端能效提高;在固定送回风温差的情况下,送风温度越低,IT设备运行功耗越低,机房包间总能耗越低。
Abstract：
The high energy consumption issue of data centers becomes the focus of attention from all parties. This paper conducts a test study on the impacts of different set temperatures of supply and return air at the air conditioning terminals in the business compartments of a data center in Shanghai on the operating energy consumption of the air conditioning terminals, the operating energy consumption of IT equipment, and the energy efficiency of the air conditioning terminals. The research discovers that as the temperature difference between the supply and return air at the air conditioning terminals increases, the overall operating energy consumption of the computer room decreases and the energy efficiency of the air conditioning terminals improves. Under the condition of a fixed temperature difference between the supply and return air, the lower the supply air temperature is, the lower the operating power consumption of IT equipment will be, and the lower the total energy consumption of the computer room compartments will be.
