摘要： The present invention relates to a geothermal system comprising a multitube vertically-sealed underground heat-exchanger and a method for installing same. The geothermal system comprising a multitube vertically-sealed underground heat-exchanger according to the present invention comprises: a geothermal well formed by vertically excavating a foundation; a heat pump which is arranged in the foundation, and which comprises a circulating pump; and a connection tube, an auxiliary facility, and a multitube vertically-sealed underground heat-exchanger which are buried and installed in the geothermal well, and which are connected to the heat pump such that a thermal fluid thermally restored in the geothermal well is supplied to the heat pump through the circulating pump, and the thermal fluid that has undergone heat exchange in the heat pump is recovered back to the geothermal well and thermally restored therein. The multitube vertically-sealed underground heat-exchanger comprises: a water-return head portion arranged in the lower side of the geothermal well; a water-return portion which is connected to the heat pump and the water-return header portion, and which comprises an outflow tube, a water-return connection tube, a distribution tube, and a water-return tube; and a supply portion which is connected to the heat pump and the water-return header portion, and which comprises an inflow tube, a supply/connection tube, a confluent tube, and a supply tube. The water-return header portion forms a boundary of function as the supply tube and the water-return tube are connected to and communicate with each other.

摘要： The object of the invention is a geothermal well, which comprises in a wellbore formed in the Earth's crust: a fist tube (1) comprising at least one opening in a first depth and having a first inner diameter, a first outer diameter, and a side wall which is thermally insulated at least in a portion thereof; a second tube (2) having a closed bottom in a second depth, a second inner diameter larger than the first outer diameter, and a second outer diameter; a third tube (3) having a closed bottom in a third depth, a third inner diameter larger than the second outer diameter, and a third outer diameter, wherein the first tube (1) is inside the second tube (2), a first interspace (20) is present between the first tube (1) and the second tube (2), wherein the first tube (1) has at least one opening in fluid communication with the first interspace (20), wherein the second tube (2) is inside the third tube (3), a second interspace (30) is present between the second tube (2) and the third tube (3); wherein the third depth is smaller than the second depth and the first depth is smaller than the second depth, furthermore through-holes (21) are formed in the second tube (2) above the bottom of the third tube (3), which allow fluid communication between the first interspace (20) and the second interspace (30), a first sealing element (22) is disposed in the first interspace (20) above the through-holes (21) for preventing upward flow of fluid in the first interspace (20), and a heat insulating material is disposed in at least a portion of the first interspace (20) above the through-holes (21). In a further aspect, the object of the invention is a method for establishing such a geothermal well and a method for geothermal energy production by said geothermal well.
