PROBLEM TO BE SOLVED: To provide an underground heat exchange system capable of improving heat transfer efficiency and reducing a cost.SOLUTION: An underground heat exchange system 100 comprises: an air supply pipe 102 which takes in air to be a heat medium from an outside; an air exhaust pipe 106 which exhausts the air to the outside; a heat exchange pipe 104 which is connected to the air supply pipe 102 and the air exhaust pipe 106 and entirely buried underground; and a linear flexible embedded member 118 which is arranged inside the pipes. The embedded member 118 can be taken out of the pipes through at least either the air supply pipe 102 or the air exhaust pipe 106 and can be used to clean an inside of the heat exchange pipe 104. 【課題】 本発明は、熱交換効率を改善しかつコスト低減が可能な地中熱交換システムを提供する。【解決手段】 本発明の地中熱交換システム１００は、熱媒体となる空気を外部から取り込む給気用パイプ１０２と、空気を外部へ排出する排気用パイプ１０６と、給気用パイプ１０２および排気用パイプ１０６に接続され、全体が地中に埋設された熱交換パイプ１０４と、これらのパイプの内部に配設された可撓性の線状の埋め込み部材１１８とを有する。埋め込み部材１１８は、給気用パイプ１０２または排気用パイプ１０６の少なくとも一方から取り出しが可能であり、埋め込み部材１１８を用いて熱交換パイプ１０４の内部を掃除することができる。【選択図】 図１
