摘要：
The effect of aquifer energy storage is greatly influenced by groundwater dynamic field. The influence of groundwater flow field and exchange period of the pumping and recharging wells on the operation performance of heat pump is quantitatively evaluated from the aspects of energy storage utilization rate by establishing the heat transfer model of GWHP. The ground subsidence caused by groundwater exploitation is also studied. Research results show that the increase of groundwater flow rate leads to the decrease of energy storage utilization rate,but it also reduces the risk of ground subsidence;The flow direction of groundwater and exchange period of pumping and recharging wells have little influence on ground subsidence;At the same time,the optimal exchange period of pumping and recharging wells for three different groundwater flow directions is obtained. © 2020, Solar Energy Periodical Office Co., Ltd.
