Research on Water-heat Coupled Model of Groundwater Source Heat Pump in Exploiting Energy Area
In order to solve the problem of rational distribution of the pumping wells in groundwater source heat pump system, groundwater numerical simulation method is adopted to describe migration process of groundwater temperature field by using heat migration module SEAWATV1 in Visual MODFLOW software. Water-heat coupled numerical model is established for study of hydrogeologic characteristics. The reasonable distance of the wells is simulated with different variable. On the premise of water temperature ranged no more than 2℃ , the reasonable well distance is 26. 5 m, 53. 0 m. 80. 0 m and 106. 0 m. respectively when the pumping or recharging capacity attains 300 m3/d,800 m3/d. 1 500 m3/d and 2 500 m3/d, respectively. Well distance and the amount of pumping and recharging have obviously impact on the change of temperature field and it has regularity. Therefore, reasonable distance of the wells should be determined in terms of different requirement of pumping and recharging wells in water source heat pump system.
