严寒地区数据中心冷却塔供冷空调系统不同模式下的节能分析
Air conditioning system energy consumption of data center in severe cold zone
摘要：
结合内蒙古呼和浩特地区某数据中心空调工程，计算了冷却塔供冷空调系统的能耗，分析了免费供冷及预冷工况下冬夏季冷却水同流量和同温差模式下运行能耗的变化。结果表明，同温差模式的节能效果略优于同流量模式。

Abstract：
Calculates the energy consumption of the air conditioning system based on a data center project located in Hohhot. Compares the energy consumption of cooling water in the operating mode of constant flow rate and temperature difference under the conditions of free cooling and pre-cooling in winter and summer, respectively. The results indicate that the constant temperature difference mode can save more energy than constant flow rate mode.
