基于全球典型城市全年气象参数的数据中心空调系统节能性分析
Energy efficiency analysis of data center air conditioning systems based on annual meteorological parameters in typical global cities
摘要：
数据中心空调系统能耗与室外气象参数紧密相关，全球不同区域的数据中心空调系统能耗有很大差异。结合全球四大典型城市（纽约、伦敦、北京、上海）的气候特点，总结了数据中心常用水冷式冷水系统的优化措施，分析了优化后国内外数据中心空调系统的节能性。

Abstract：
The data center air conditioning system is closely related to the outdoor meteorological parameters, and the energy consumption of the data center air conditioning system varies greatly in different regions of the world. Based on the climate characteristics of four major cities in the world, including New York, London, Beijing and Shanghai, this paper summarizes the optimization measures of water-cooled chilled water systems commonly used in data centers, and analyses the energy saving performance of the optimized data center air conditioning system at home and abroad.
