COMBINED TYPE GEOTHERMAL SYSTEM AND CONSTRUCTION METHOD USING LARGE APERTURE PUNCHUNG

摘要

The present invention utilizes a hybrid geothermal system in a large-diameter drilling, and drilling to a planned depth from the ground surface After the formation of the underground water reservoir formed with a certain amount of a certain thickness of reinforced concrete on the inside of the underground; Yugonggwan and provided with a plurality of perforations to a number provided in the vertical predetermined intervals along the circumferential direction of the side wall in the sidewall of the water reservoir, is inserted into the perforation holes can facilitate the flow of ground water to the interior of the water reservoir, the the upper valve and the lower valve provided in the composite the composite heat exchanger pipe and an open and a closed pipe system installed in the water reservoir to apply a hermetic heat pipe type heat pipe with a vertical mixing pipe of the horizontal heat exchange to selectively apply and; Is achieved by the hybrid system utilizing geothermal drilling large diameter, characterized in that it comprises a filling material is filled on top of the water reservoir to the geothermal protection. Thus, by taking advantage of the underground and ground water or water-filled underground space large Jung Ho structure, the number of conventional sealed the hole is not necessary, as in the case of the advantage of reducing the land area available as well as underground installation of the heat inside increase the contact area with the underground heat transfer medium and can be performed effectively it is effective to increase the heat exchange efficiency of the underground heat exchanger. The present invention, by applying an open and a closed-efficient geothermal system at the same time and can be utilized to eliminate the risk of groundwater level change, depending on the switchgear installation it is possible to change an open and a closed it is possible to utilize an efficient geothermal. And the benefits that can be freely groundwater inflow to form a horizontal or radial direction of the hole of the aquifer in the water reservoir. In addition, the construction zone is reduced effects have been questioned in the existing structure, enclosed by taking advantage of the large Jung Ho, do not perform internal charging value maintenance of geothermal systems and peripherals can be easily effect. As a result, by applying the present invention can be sealed and can take advantage of all the benefits of an open can be utilized not only among the closed equilibrium with vertical construction cost and construction period reduction, maintenance is easy and the overall geothermal has the effect of improving the efficiency of the heating and cooling system. ;
