| Outline of Final Research Achievements |
The heat-cluster type geothermal heat pump that positively uses groundwater can collect 4 to 5 times as much heat as the conventional bore-hole type that mainly uses soil heat. It is necessary to elucidate the complicated heat transport in soil including the movement of groundwater for the diffusion. Therefore, in this research, by developing the numerical analysis model of this complex system based on the test results by the actual equipment and the model experiment of soil and groundwater, a part of the heat and mass transport phenomena in the heat-cluster type geothermal heat pump could be revealed.

| Academic Significance and Societal Importance of the Research Achievements |
地下水を積極的に利用するヒートクラスター型地中熱ヒートポンプの複雑な熱移動現象の解明のために実機による試験ならびに土壌中の地下水の移動に関するモデル実験を行った。それらの結果を元に数値計算モデルの開発を行い熱移動現象の解明を試みた。
このような試みはこれまでになされておらず、ヒートクラスター型地中熱ヒートポンプの複雑な熱移動現象の解明により、このタイプのヒートポンプの設計指針を与えることができれば地中熱ヒートポンプの普及に拍車がかかる．
