【摘要】：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%。
[Abstract]:The problem of high energy consumption in the data center has greatly hindered the development of the information industry. The utilization of natural cold sources is the key technical means to realize the energy saving and consumption reduction of the data center. The article uses the natural cold source of the data center as the research object, and determines the recommended value of the critical wet bulb temperature for the natural cold source and profit under the indirect cooling mode of the evaporative cooling. The natural cold source utilization potential in the main climate area was used, and the concept of natural cold source utilization sensitivity was put forward. A typical data center in hot summer warm winter warm area was taken as an example to analyze the energy saving effect of natural cold source. The result showed that the natural cold of the natural cold source in the data center was 16 degrees centigrade when the limit of the critical wet bulb temperature was used, and the natural cold in most areas of the country was cold. The source utilization rate is over 50%, and the natural cold source in the mild area is the most sensitive. The comprehensive COP value can be increased by 23.7% and the energy saving rate is 19.2%. in the summer heat and winter warm area data center using natural cold source.
