<p>The present invention relates to utilization of a geothermal renewable energy among new renewable energy sources. According to the present invention, the ground heat conductivity of a ground heat exchanger can be improved and rock debris generated during perforation can be reused. Therefore, processing costs and time can be saved. The method of the present invention can be applied to new renewable energy sectors for using ground heat for heating and cooling, a heating and cooling device for farming, and construction of heating and cooling devices for constructing houses, buildings, and pensions. The method of the present invention has effects of improving thermal conductivity, reducing bentonite consumption, performing filling operations without grouting equipment using natural gravity filling, reducing construction costs, reducing construction time, and facilitating construction.</p> |
