【摘要】：數(shù)據(jù)中心高能耗問題大大阻礙了信息產(chǎn)業(yè)的發(fā)展,自然冷源利用是實(shí)現(xiàn)數(shù)據(jù)中心節(jié)能降耗的關(guān)鍵技術(shù)手段。文章以數(shù)據(jù)中心自然冷源利用為研究對象,確定了蒸發(fā)冷卻間接供冷方式下自然冷源利用臨界濕球溫度的推薦值;分析了全國主要?dú)夂騾^(qū)自然冷源利用潛力;提出了自然冷源利用敏感性的概念;以夏熱冬暖地區(qū)某典型數(shù)據(jù)中心為例進(jìn)行了自然冷源利用的節(jié)能效果分析。結(jié)果表明:數(shù)據(jù)中心自然冷源利用的臨界濕球溫度上限為16℃時,全國大部分地區(qū)的自然冷源可利用率超過50%;溫和地區(qū)自然冷源敏感性最高;夏熱冬暖地區(qū)數(shù)據(jù)中心利用自然冷源時,全年綜合COP值可提高23.7%,節(jié)能率為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.
