摘　　要：数据中心是信息行业的核心基础设施,其能耗巨大,我国数据中心电能使用效率(power usage effectiveness,PUE)远高于发达国家,开展数据中心节能研究具有重要的科学意义。本文从数据中心冷却节能中的核心问题出发,从自然冷却、气流组织优化、蓄冷三个方面对近年来国内外数据中心冷却节能的研究进展进行了阐述,提出自然冷却技术应因地制宜地采用,并应针对自然冷源条件差的地区开展更深入的研究;气流组织优化应在现有气流控制方式基础上针对高功率密度机柜开展机柜级气流组织优化研究;蓄冷技术能为数据中心运营商带来巨大的经济效益,也能给发电和电网输配效率带来巨大提升,现有蓄冷技术蓄冷密度有待提升,针对数据中心应用场景的蓄冷控制策略优化研究应当引起重视。Data centers represent the core infrastructure of the information industry.The energy consumption of data centers is a concern,as their power usage effectiveness(PUE)in China is much higher than that in the developed countries.So it is of great significance to conduct research on data center energy conservation.This paper focuses on the recent research advances in data center cooling systems from three perspectives:natural cooling,airflow organization optimization and cold storage.It is proposed that natural cooling technology should be adopted according to local conditions and that more in-depth research should be conducted in areas with poor natural cold source conditions.In addition,airflow organization optimization should enhance cabinet-level airflow organization for high-power density cabinets based on existing airflow control methods.Moreover,cold storage technology can bring data center operators huge economic benefits as well as substantial improvements to power generation and grid transmission distribution efficiency.Therefore,the existing cold storage technology cooling density needs to be improved,and further study should be conducted on the cold storage control strategies for optimal use in data centers.
