New methods to spatially extend thermal response test assessments
(International Ground Source Heat Pump Association, 2017)
Thermal response tests (TRTs), used to evaluate the subsurface thermal conductivity when designing ground source heat pump systems, are spatially limited to the vicinity of the borehole where a test is carried out. The ...
Measurement of internal and effective borehole resistances during thermal response tests
(International Ground Source Heat Pump Association, 2017)
In a conventional thermal response test (TRT), the main parameter evaluated is the bulk subsurface thermal conductivity surrounding the borehole. It is also possible to evaluate the borehole thermal resistance. Several ...
