摘　　要：对某办公楼地下水地源热泵回灌井的最佳回扬强度、最佳回扬间隔时间进行试验研究。地下水地源热泵回灌井定期回扬可以及时清除回灌井中的暂时性堵塞物,疏通回灌水的运移通道,保证回灌效果。该办公楼地下水地源热泵回灌井的最佳回扬强度为48 m^(3)/h,最佳回扬间隔时间为7 d。An experimental study on the optimal pumping intensity and optimal pumping interval time of groundwater ground-source heat pump recharge well inan office building was conducted.Regular pumping from groundwater ground-source heat pump rechargewells can timely remove temporary blockages in recharge wells,dredge the transport channel of rechargewater,and ensure the recharge effect.The optimal pumping intensity of the ground water ground-sourceheat pump recharge well in the office building is 48m^(3)/h,and the optimal pumping interval time is 7 days.
