New borehole heat exchangers in the Geoenergetics Laboratory at the Faculty of Drilling, Oil and Gas, AGH UST in Krakow

Abstract

The Geoenergetics Laboratory at the Faculty of Drilling, Oil and Gas in Krakow is presented in this paper to mark its 10th anniversary. The origins of the Laboratory, its equipment and the design of borehole heat exchangers belonging to the field research station are also discussed. Recently, the construction of 14 new borehole heat exchangers was designed and the boreholes will be drilled in the area of AGH University. They will perform heating and cooling for the new S1 building of the University. Every borehole heat exchanger will be tested, with the effective thermal conductivity and borehole thermal resistivity calculated after a thermal response test on every borehole. The differ? ence between boreholes should show the difference of borehole thermal resistivity, but the effective thermal conductivity should be the same.
