# .AixLib.Fluid.Geothermal.Borefields.BaseClasses.Boreholes.BaseClasses.PartialInternalHEX

Partial model to implement the internal heat exchanger of a borehole segment

## 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: cp (`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`.
- January 24, 2014, by Michael Wetter:
  Revised implementation, added comments, replaced `HeatTransfer.Windows.BaseClasses.ThermalConductor` with resistance models from the Modelica Standard Library.
- January 23, 2014, by Damien Picard:
  First implementation.
