摘要
为了降低南方沿海地区数据中心的能耗,加强其水蓄冷系统的分析,基于珠三角地区数据中心的冷负荷以及当地的分时电价政策,选用水蓄冷系统作为蓄能方案。首先,优化了水蓄冷系统和运行控制方案;其次,分析了典型日、典型月、全年水蓄冷系统的运行情况、能耗及经济性。结果表明:优化的水蓄冷系统能够保证室内末端负荷需求且高效运行,全年供冷运行费降低25.78%,具有良好的“削峰填谷”作用,供冷电费显著降低。
In order to reduce the energy consumption of data centers in the southern coastal region and enhance the analysis of the water cold storage system,the water cold storage system was selected as the energy storage solution based on the cooling load of data centers in the Pearl River Delta region and the local time-of-use tariff policy.First,the water cold storage system and operation control scheme were optimized;second,the operation situation,energy consumption and economy of the water cold storage system were analyzed for typical days,months and whole year.The results show that the optimized water cold storage system can guarantee the indoor end-load demand and operate efficiently,and the annual cooling operation cost is reduced by 25.78%,which has a good effect of"peak-load shifting effect"and reduces the cooling electricity cost significantly.
