Abstract:: This paper used the Anyang Fifth People’s Hospital as the case of study.The experiments were implemented with the patterns of "2 pumping wells and 2 recharging wells" and "2 pumping wells and 4 recharging wells".The change of groundwater flow field and temperature field in the two patterns designed in ground temperature air-conditioning project operation were simulated by using a groundwater hydrodynamic model and a hydrothermal coupling mathematical model.Results indicated that the influence of ground temperature air-conditioning project on groundwater flow field and temperature field were very different in different pumping-recharging patterns.The increase of single-well recharge quantity enhanced the influence scope and range,making it easier to form heat transfixion.The way of groundwater transferring heat via groundwater also varied during different running periods.
