Geothermal Response Test

Geothermal response test on an already installed borehole heat exchanger (BHE):

  • connecting the measuring device to the prepared BHE and removing the air from the system
  • starting the test
  • test duration: approximately 48 hours
  • disconnecting the measuring device from the BHE
  • taking 4 recordings of the temperature profile for the whole depth:
    one before the test, followed by 1, 2 and 3 hours after the test has finished

Evaluation of the test results with the GeRT-CAL-2-0-10 software]

  • determining the thermal conductivity [] of the soil
  • determining the borehole thermal resistance
  • evaluating and interpreting the temperature profile with depth
