摘要
通过对服务器浸没式液冷实验台进行测试,得出了在不同室外侧温度、不同服务器发热功率条件下该实验系统的制冷PUE(能源使用效率)。实验结果表明,该系统制冷PUE值在1.05~1.28之间。室外侧温度为39℃,负载功率为3.773k W,制冷PUE达到最小值1.056。本文得出上海市数据中心全年运行制冷PUE值为1.060。使用浸没式液冷的数据中心其冷却系统能耗仅为使用传统精密空调的10%左右。
The cooling PUE(Power Usage Effectiveness) of the experimental system under different outdoor temperature and different server heating power was obtained by testing the experimental platform of liquid immersion cooling systems. The experimental results show that the cooling PUE value of the system is between 1.05~1.28. When the outdoor temperature was 39 ℃ and the load power was 3.773 k W, the cooling PUE reached the minimum value of1.056. The annual cooling PUE value in Shanghai data centers is 1.060. The cooling system energy consumption of data centers using liquid immersion cooling systems is only about 10% of that of traditional precision air conditioners.
