Information

Partial model to implement models simulating the thermal and fluid behaviour of a borehole segment.

The thermodynamic properties of the fluid circulating in the borehole are calculated as protected parameters in this partial model: c_p (cpMed), k (kMed) and μ (muMed). Additionally, the following parameters are already declared as protected parameters and thus do not need to be declared in models which extend this partial model:

• Rgb_val (Thermal resistance between grout zone and borehole wall)
• RCondGro_val (Thermal resistance between pipe wall and capacity in grout)
• x (Grout capacity location)

Revisions

• May 17, 2024, by Michael Wetter:
  Updated model due to removal of parameter dynFil.
  This is for IBPSA, #1885.
• January 18, 2019, by Jianjun Hu:
  Limited the media choice to water and glycolWater. See #1050.
• July 10, 2018, by Alex Laferrière:
  First implementation of partial model.
• June 18, 2014, by Michael Wetter:
  Added initialization for temperatures and derivatives of capFil1 and capFil2 to avoid a warning during translation.
• February 14, 2014, by Michael Wetter:
  Removed unused parameters B0 and B1.
