随着数据中心向智算化转型,单机柜功耗密度提升,冷却能耗占比高,降低数据中心电能使用效率至关重要。本文提出一种结合自然水源与液冷技术的冷却系统,以广西来宾某数据中心为研究对象,构建系统模型,分析不同控制方式和运行条件下的系统性能,并与常规水冷冷水机组冷却系统对比。研究表明:冷冻水泵控制送风温度能耗更低,节能约10% 且利于余热利用;冷却水泵控制冷冻水供水温度更节能,但节能率随水库水温的升高而下降;自然水源冷却系统全年节能率达73.5%,制冷负载系数为0.05,低于常规系统;送风温度设定点高时系统能耗波动小,综合考虑选取 28 ℃较合适。该研究为绿色节能数据中心冷却系统设计提供了参考。
Owing to the transformation of data centers toward intelligent computing, the power density per cabinet has increased, with cooling-energy consumption constituting a significant proportion. Reducing the power-usage effectiveness (PUE) of data centers is crucial. This study proposes a cooling system that combines natural water sources with liquid-cooling technology. Considering a data center in Laibin, Guangxi as the research object, a system model is constructed to analyze the system performance under different control methods and operating conditions; subsequently, it is compared with conventional water-cooled chiller cooling systems. The result shows that controlling the supply-air temperature through the chilled-water pump reduces energy consumption by approximately 10% energy as well as facilitates waste-heat utilization. Additionally, controlling the chilled water-supply temperature through the cooling water pump is more energy efficient, although the energy-saving rate decreases as the reservoir water temperature increases. The natural water-source cooling system achieves an annual energy-saving rate of 73.5% with a cooling load factor of 0.05, which is lower than that of the conventional system. When the supply-air temperature setpoint is higher, the system energy consumption fluctuates less. Based on a comprehensive consideration, 28 ℃ is a suitable temperature. This study provides a reference for the design of green and energy-efficient data-center cooling systems.
