The present invention is to eliminate the automatic driving having a yeolseomhwa prevention device group type relates to a vertical hermetic geothermal system, not collectively a certain space can only occur by installing a vertical sealed underground heat exchanger, operating yeolseomhwa phenomenon depending on soil temperature , it is collectively installed in the same depth and groundwater, excavation depth around vertical sealed underground heat exchanger in groundwater with a deep depth of more than 30m than digging depth of vertical sealed underground heat exchanger on the inside of the space to be installed vertically sealed underground heat exchanger It is provided with a protection yeolseomhwa consisting of a temperature sensor for sensing the water pumps and the underground heat pumped groundwater.
Thus, when the surrounding ground heat in continuously operating collective vertically sealed underground heat exchanger is installed rises to a certain temperature yeolseomhwa prevent the temperature of the sensor to detect the underground heat, so as to operate the yeolseomhwa prevent negative submersible pumps naemeurosseo spread the groundwater out, outside a groundwater with fresh soil temperature and soil absorbs heat from the surrounding higher, coming yeolseomhwa prevent moving parts undergo a process after being discharged out through the yeolseomhwa prevent it. Therefore, since the lower the soil temperature around vertical collectively sealed underground heat exchanger is installed, to prevent the phenomenon of vertical yeolseomhwa sealed underground heat exchanger and the cooling efficiency of the vertical sealed nopyige geothermal system.
