摘要
PURPOSE: A solar thermal and geothermal heat pump hybrid system with an underground solar heat storage device is provided to operate without installing a long-term solar heat storage tank or a seasonal heat storage device because solar heat is stored under the ground using a heat storage pipe for a geothermal heat exchanger or a single composite pipe. CONSTITUTION: A solar thermal and geothermal heat pump hybrid system with an underground solar heat storage device comprises a solar heat collecting device (10), a heat storage pipe (20), a heat source supplying pipe (30), and a heat pump device (40). The solar heat collecting device collects and supplies solar heat energy. The heat storage pipe is connected to the solar heat collecting device and is formed under the ground, thereby storing the solar heat energy of the solar heat collecting device under the ground in summer season. The heat source supplying pipe is formed under the ground where the heat storage pipe is formed and is connected to the heat pump device, thereby transferring heat source stored under the ground to the heat pump device in winter season. The heat pump device heat-exchanges the underground heat source receiving from the heat source supplying pipe so that heat source for hot water and heating can be supplied to used places.
