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 present invention relates to a geothermal system using a single water supply system for heating and cooling a smart farm and a building, and a method for constructing the geothermal system, and the purpose of the present invention is to operate one pump even for a large geothermal capacity by configuring a plurality of geothermal holes and a single water supply facility (a water supply well or water supply geothermal hole), connecting the geothermal holes and the water supply facility to collect underground water in the water supply facility, and then supplying the underground water to a heat pump. The geothermal system using a single water supply system for heating and cooling a smart farm and a building, according to the present invention, comprises: at least two geothermal holes (1) formed in the ground; a return water circulation tube (10) for returning underground water of the geothermal holes; a water collection and supply well (20) for collecting and then supplying the underground water returned by the return water circulation tube; at least one heat pump (30) for generating heat for cooling and heating, by using, as a heat source, the heat of the underground water supplied by the water collection and supply well; and a supply tube (40) which is an underground water supply means for supplying, to the geothermal holes, the underground water that supplied heat to the heat pump.
