Temperature footprint of a thermal response test can help to reveal thermogeological information
Brattli, Bjørge; Liebel, Heiko T.; Huber, Kilian; Frengstad, Bjørn S.; Ramstad, Randi K. (NGU Bulletin (451), Journal article, 2011)Borehole heat exchangers connected to a ground-coupled heat pump extract heat from the ground for the heating of buildings. Heat is transferred to the ground in cooling mode and can be extracted again during the next heating ... -
Thermogeology in the Oslo region and Kristiansand - results from thermal response tests (TRT) with and without artificially induced groundwater flow
Ramstad, Randi K.; Brattli, Bjørge; Liebel, Heiko T.; Huber, Kilian; Frengstad, Bjørn (NGU-Rapport (2009.069), Report, 2009)Thermal response tests (TRT) are widely used to measure the effective thermal conductivity and borehole resistance in a well. The gained data serve as the basis for the dimensioning of larger ground-source heat-pump ...
