| Abstract | 数据中心高能耗问题大大阻碍了信息产业的发展,自然冷源利用是实现数据中心节能降耗的关键技术手段。文章以数据中心自然冷源利用为研究对象,确定了蒸发冷却间接供冷方式下自然冷源利用临界湿球温度的推荐值；分析了全国主要气候区自然冷源利用潜力；提出了自然冷源利用敏感性的概念；以夏热冬暖地区某典型数据中心为例进行了自然冷源利用的节能效果分析。结果表明：数据中心自然冷源利用的临界湿球温度上限为16℃时,全国大部分地区的自然冷源可利用率超过50%；温和地区自然冷源敏感性最高；夏热冬暖地区数据中心利用自然冷源时,全年综合COP值可提高23.7%,节能率为19.2%。 |
| Other Abstract | The high energy consumption of data center presents a major barrier to the development of information industry,while the utilization of natural cold sources is very important to realize energysaving and consumption-reduction.This paper mainly studies the utilization of natural cold sources in data center.The recommended values of the critical wet bulb temperature of natural cold sources under evaporative cooling conditions are determined.The utilizing potential of natural cold source in major climate regions of China is analyzed in detail.Moreover,the concept of natural cold source sensitivity is introduced.In addition,a typical data center in hot summer and warm winter zone is taken as an example to analyze the energy-saving effect of natural sold sources.The result indicates that natural cold source utilizing ratio in data centers exceeds 50% in most regions at a critical wet bulb temperature of 16 ℃.However,the temperate region had the highest sensitivity concerning the natural cold source.Annual comprehensive COP value of data centers increases by 23.7%,and the energy saving rate is about 19.2% when using natural cold sources in hot summer and warm winter zone. |
