上海某能源中心空调系统实际运行效果分析

Analysis of the Practical Operation Effect for Air-conditioning System of a Energy Center in Shanghai

论文以上海某能源中心冰蓄冷系统为案例,对其实际运行工况性能进行了实测,对该系统运行效率进行了分析,并对冰蓄冷空调系统与常规空调系统运行费用进行了比较。结果表明,该能源中心空调主机和各级水泵的实际运行效率均较好。相比常规空调系统,该冰蓄冷空调系统年节省运行费用约为45%,高峰用电量转移率约为60%,节省运行费用和移峰填谷效果均明显,这可为区域供冷技术与冰蓄冷系统联合应用提供参考依据。

a case is provided about ice storage system of a energy center in Shanghai in this paper. The performances of the operational condition are measured and the operational efficiency of the system is analyzed and the running cost of ice storage air conditioning system and conventional air conditioning system is compared. Results indicate that the operation efficiency is good on the refrigeration unit and pumps of energy center. Meanwhile, it also shows good result because the ice storage air conditioning system can save the running cost is about 45% and the transfer rate of power consumption is about 60% in peak stage, which is providing references for application technology of district cooling and ice storage.
