Data for heat charging / discharging experiments of a high-temperature coaxial borehole heat exchanger in saturated sand

This data file contains experimental measurement data of a set of four heat charging / discharging experiments performed between December 2020 and June 2021 at the Geotechnikum of the Institute of Geosciences at Kiel University (Germany) in order to examine the heat transfer behaviour of a high-temperature coaxial borehole heat exchanger (BHE) analogue in a permable saturated porous sand medium at the laboratory scale.
