Resumen de: KR101670007B1

The present invention relates to a borehole-type seasonal heat storage system, and more specifically, to a borehole-type seasonal heat storage system capable of selecting a heat storage space according to a supply temperature of a heat source. A first heat storage pipe member comprises a supply pipe and a collection pipe formed in an annular shape, and is formed on a lower surface, wherein a U-shaped vertical pipe is connected to be inserted into a borehole. An n^th heat storage pipe member has a supply pipe and a collection pipe having diameters larger than the diameters of the supply pipe and the collection pipe of the first heat storage pipe member. Then the n^th heat storage pipe member is arranged on the outside of the first heat storage pipe member at a proper interval to form a seasonal heat storage body. A supply temperature of a heat source entering a main supply pipe and an underground temperature of each portion of the seasonal heat storage body are measured to supply heat to the first or the n^th heat storage pipe member corresponding to a corresponding temperature according to the supply temperature of the heat source to store heat to increase heat storage performance.
