| 摘 要： | 为研究地源热泵系统(GSHPs)在不同负荷分布下的长周期运行特性,建立了考虑地下水渗流的地下埋管换热系统的传热模型,并对北京、哈尔滨、上海三典型负荷分布地区某宾馆建筑地源热泵系统连续10年的长周期运行特性进行了计算与分析.结果表明,在北京负荷平衡地区热累积效应较小,而在哈尔滨(负荷比6.6∶1)地区盘管最高及最低出水温度10年降低了3.8℃,年均降幅为0.38℃/a;上海(负荷比1∶3.6)地区,盘管最高与最低出水温度上升了约5.6℃,年均升幅0.56℃/a.

| Abstract: | In order to study the long-term operation characteristics of the ground source heat pump system(GSHPs)in various building load distributions,the heat transfer model considering the groundwater seepage of the underground heat exchanger system is established.The 10-year continuous simulations of GSHPs for hotel buildings in Beijing,Harbin and Shanghai with the typical load distribution are performed,and the long-term operation characteristics of GSHPs in regions are analyzed.The results show that the influenc... |
