摘　　要：利用单井循环地下换热系统砂箱实验台,以沈阳地区供暖期和空调期时间为依据,开展了抽灌同井夏冬、冬夏2种运行模式下储能特性的实验研究。结果表明:该砂箱实验台中的含水层自身温度恢复能力较差,在系统运行间歇期,含水层温度不能恢复至初始状态;抽灌同井在热负荷占优的地区运行时,必须采用辅助技术手段,对地下含水层进行热量补给,保证系统长期可靠运行;建议系统先进行夏季放热工况运行,补充含水层储热量,再进行冬季取热工况,保持热源井的抽水温度和热泵系统运行效率均处在较高水平。Using an experimental sandbox of single well cycling ground heat exchanger system, according to the heating and cooling period in Shenyang, carries out an experimental research on energy storage characteristics in two operating modes of summer-winter and winter-summer. The results show that the ability of aquifer temperature recovery is Ix）or, and the aquifer temperature cannot return to its initial state during the intermittent period. In the heat load dominated area, assistant technology must be used during the operating of pumping and recharging well. Heat supply of the aquifer is needed to ensure long- term reliable operating of system. Suggests that the system firstly operates in the heat release condition in summer to supply the aquifer storage heat, and then the heat absorption is carried out in winter. The outlet water temperature and the coefficient of performance （COP） of heat pump system are both kept at a high level.
