| 摘 要： | 探讨了地下含水层储能系统回灌期输入地下含水层的能量、火用及抽水期从地下含水层回收的能量、火用的计算公式。通过算例,计算了大流量、低回灌水温度,小流量、高回灌水温度及适中的流量、回灌水温度的3种工况的储能效率及火用效率,小流量、高回灌水温度运行模式的火用效率最高。将水泵消耗的电能计入火用效率,对火用效率进行修正,小流量、高回灌水温度运行模式具有更大的优势。

| Abstract: | Energy and exergy calculation equations of underground aquifer energy thermal storage system during reinjection period and pumping period are discussed.Through some calculation examples,energy storage and exergy efficiencies are calculated under three conditions,including large flow and low reinjection water temperature,small flow and high reinjection water temperature,and moderate flow and reinjection water temperature.The operation mode at the small flow and high reinjection water temperature has the maximum exergy efficiency.By taking electricity consumption of pump into account to modify the exergy efficiency,the operation mode at the small flow and high reinjection water temperature has even more advantages. |
