简要阐述了数据中心空调供冷特点及能耗现状,论述了气流组织在改善数据中心热环境方面的重要性。进一步分析了机房空调上送风方式与下送风方式的优缺点,并就某小型数据中心的气流组织进行了试验研究,分析实际测得的温度场及速度场,得到服务器热流密度的大小对机柜进风温度、速度有显著影响的结论。
The characteristics and energy consumption status of air conditioning in data center are briefly described. The importance of airflow organization in improving the thermal environment of data center is discussed. Further analyzed the advantages and disadvantages of the air supply mode and the lower air supply mode in the engine room air conditioner, and conducted an experimental study on the air flow organization in a small data center. The actual measured temperature field and velocity field were analyzed to obtain the size of the server heat flux density Cabinets into the air temperature, speed has a significant impact on the conclusion.
