<p>According to the present invention, a ground heat exchange system is installed in an underground geothermal hole to use warmth from the ground during the winter and low heat from the ground during the summer. The ground heat exchange system comprises: a ground heat exchange pipe to exchange heat with the ground; a filler filling a space between the ground heat exchange pipe and the geothermal hole; a heat pump connected to the ground heat exchange pipe; and a cooling and heating member connected to the heat pump to be installed inside a building. According to the present invention, the ground heat exchange system has the ground heat exchange pipe installed in the underground geothermal hole to exchange heat with the ground and fills the space between the geothermal hole and the ground heat exchange pipe with the filler as a phase change material, thereby improving heat efficiency through heat recovery.</p> |
