The present invention relates to an apparatus for obtaining water resources data of a geothermal system, which accurately measures and calculates the temperature and amount of underground water in real time such that when a plurality of geothermal holes are operated together, workable thermal load capacity of each geothermal hole is calculated to allow an operation suitable for each calculated thermal load capacity. The apparatus for obtaining water resources data of the geothermal system comprises: a water level sensor (30S) installed on the interior of the geothermal hole to sense the water level of the water supply side of the interior of the geothermal hole; a water supply side temperature sensor (40S) and a water supply side water gauge (50S), which are installed to the water supply system supplying underground water in the water supply side of the interior of the geothermal hole to a thermal exchange means and sensing the temperature and amount of underground water in the water supply side, respectively, the underground water flowing along the water supply system in a water supply direction; a water returning side temperature sensor (40R) and a water returning side water gauge (50R), which are installed to the water returning system returning underground water in a water returning side, which passes through the heat exchanging means, to the geothermal hole and sensing the temperature and returned amount of underground water in the water returning side, respectively, the underground water flowing along the water returning system in the water returning direction; a controller (60) calculating the circulation calories in accordance with the equation Q = WCΔt [Q:calculation calories, W:amount of underground water (amount in water supply side or water amount in water returning side), C:specific heat of underground water, and Δt: t1 (temperature of underground water in the water supply side) - t2 (temperature of underground water in the water returning side)] based on sensed values of the water supply side water gauge, the water returning side water gauge, the water supply side temperature sensor, and the water returning side temperature sensor; and a communication module transmitting underground water data including the circulation calories calculated by the controller to a central control room through wire/wireless communication. |
