    • Measurement of internal and effective borehole resistances during thermal response tests 

      Lamarche, Louis; Raymond, Jasmin; Koubikana Pambou, Claude Hugo (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 ...

    • Nanocomposite materials used for ground heat exchanger pipes 

      Gosselin, Jean-Sébastien; Raymond, Jasmin; Gonthier, Stéphane; Brousseau, Mathieu; Lavoie, Jean-François (International Ground Source Heat Pump Association, 2017)
      This study compares the performance of single U-pipe, double U-pipe, and coaxial ground heat exchangers (GHE) equipped with standard HDPE and thermally enhanced (TE) pipes. Sizing calculations and 10-year hourly simulations ...

    • New methods to spatially extend thermal response test assessments 

      Raymond, Jasmin; Malo, Michel; Lamarche, Louis; Perozzi, Lorenzo; Gloaguen, Erwan; Bégin, Carl (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 ...
