PURPOSE: A terrestrial heat exchange system through ground-water run-off control is provided to control the outflow of ground water in bore holes in consideration of the reference temperature and level of the ground water. CONSTITUTION: A terrestrial heat exchange system through ground-water run-off control comprises one or multiple bore holes(1), storage tubes(2), a deep well pump(3), a terrestrial heat pump(7), an outflow valve(10), a return valve(12) and a controller(13). The water of aquifer is stored in the bore holes. The storage tubes store the ground water provided to the terrestrial heat pump for heat exchange. The deep well pump with a pressure water level gauge(31) discharges the ground water of each storage tube. The terrestrial heat receives the ground water for heat exchange and performs heat exchange. The outflow valve is formed in a point of a return pipe(9) connected to the bore holes and is opened to let the ground water flow out. The return valve allows or blocks the flow of the ground water returned to the bore holes. When the temperature of ground water in the bore holes during heating/cooling is over a reference temperature, the controller discharges a certain amount of the ground water so that external ground water flows into the bore holes, thereby maintaining the reference temperature.
