| 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.
