摘要
结合一地源热泵示范工程,建立了垂直竖井与地基桩单 U 型管埋地换热器联合使用的地源热泵系统的综合性能实验装置。通过对全年运行测试数据的分析,研究了地下换热器的进出水温差和平均温度,冬夏季地源热泵的吸(排)热量、制热(冷)量及循环性能,为地源热泵的工程设计提供了参考。
The experimental equipment of GSHPs integrating U-pipe pile heat exchangers and borehole heat exchangers is sets up. According to the data of one year running, the temperature difference of in-let and out-let water in the pipe, the average water temperature, theheat absorption(excluding)quantityand heating(refrigerating) quantity are studied.
