WebContact. Testing period: 1 week on average. Description of the service provided: – First step: Install the testing apparatus at the site. – Second step: Perform the TRT (measure the various parameters needed to determine the ground’s conductivity over a period of 72 hours ) – Third step: Remove the testing apparatus and harvest the data. WebNov 1, 2024 · The thermal response test (TRT) is a highly developed and widespread method for measuring ground thermal conductivity using ground source heat exchangers (GHEs). However, its application is mostly limited to vertical ground heat exchangers (VGHEs), with very few previous studies on TRT with horizontal configurations.
