| Research Abstract |
In geothermal heat pump (GeoHP) systems, energy efficiency can be drastically improved with the application of well-designed heat storages. In this research, field tests and numerical simulations were carried out in a GeoHP snow-melting system with clustered heat exchange piles in Fukui City, Japan and the high energy-saving ability of the GeoHP system was successfully demonstrated. Field-wide surveys and numerical modeling of groundwater flow system in the Fukui Plain were also performed to develop a suitability map of GeoHP system in the area.
