摘　　要：通过对天津市地下水源热泵系统回灌过程中的地下水位动态特征,稳定回灌水位下的地下水回灌量的变化分析,建立回灌率、单位灌采比、单井回灌能力表征指标,并对南开大学综合楼与医科大第二医院地下水源热泵系统回灌能力评估。结果表明:回灌井单位回灌量一般在0.6~1.60 m3/h·m之间,单位灌采比在0.3~0.6之间,单井回灌能力与地下水源热泵井单位回灌量、稳定水位埋深具有线性相关。含水层水文地质条件、成井工艺、回灌方式及地下水源热泵系统运行管理对回灌效果有很大的影响。该研究结果可为地下水源热泵系统建设与科学运行管理提供依据。Based on the analysis of the dynamic characteristics of groundwater level during the recharge process and the change of groundwater recharge volume under the stable recharge level of groundwater source heat pump system in Tianjin,the characterization indexes of recharge rate,unit recharge and production ratio and single well recharge capacity are established,and the recharge capacity of groundwater source heat pump system in comprehensive building of Nankai university and the second hospital of Tianjin medical university is evaluated.The results show that:The unit recharge volume of recharge wells is generlly between 0.6 and 1.60 m'/h.m,and the unit recharge-pump ratio is between 0.3 and 0.6.The recharge capacity of single well is linearly related to the unit recharge volume of groundwater source heat pump well and the buried depth of stable water level.Aquifer hydro-geological conditions,well completion technology,recharge mode and operation management of groundwater source heat pump system have great influence on effect of recharge.The research results can provide the basis for the construction andscientific operation management of the groundwater source heat pump system.
