.Buildings.Fluid.Geothermal.Boreholes.BaseClasses.BoreholeSegment

Information

Horizontal layer that is used to model a U-tube borehole heat exchanger. This model combines three models, each simulating a different aspect of a borehole heat exchanger.

The instance pipFil computes the heat transfer in the pipes and the filling material. This computation is done using the model Buildings.Fluid.Geothermal.Boreholes.BaseClasses.HexInternalElement.

The instance soi computes transient and steady state heat transfer in the soil using a vertical cylinder. The computation is done using the model Buildings.HeatTransfer.Conduction.SingleLayerCylinder.

The model TBouCon computes the far-field temperature boundary condition, i.e., the temperature at the outer surface of the above cylindrical heat transfer computation. The computation is done using the model Buildings.Fluid.Geothermal.Boreholes.BaseClasses.SingleUTubeBoundaryCondition.
