During design of Governmental District the geothermal heat pump technology was also arisen to heating and cooling.
1x125 m BHE was installed in Budapest IX. district in 2008 and we carried the Thermal Response Test out. The pipe was single U.
At first we measured the undisturbed in situ temperature in the BHE after drilling and after that the TRT was carried out. The inlet, outlet temperature, mass flow and air temperature were recorded. The result of evaluation was the thermal conductivity value.
