These pictures show the geothermal heat-pump system installed at an office of Department of Groundwater Resources in Kamphaengphet, Thailand in October, 2006 through our research project.
Top pictures: installation of double U-tubes into a heat exchange borehole. Left: extending the U-tubes. Right: inserting the U-tube into the borehole.
Down left: connection of U-tube and plastic pipes from the heat exchange borehole to a heat-pump. Down right: cool air from the fan coil in a room, which is cooled by the geothermal heat-pump system. Itÿ?s cool!
