Partial model to implement multi-segment boreholes
Extends from BuildingSystems.Fluid.Interfaces.PartialTwoPortInterface, BuildingSystems.Fluid.Interfaces.TwoPortFlowResistanceParameters.
Information
Partial model to implement models simulating geothermal U-tube boreholes modeled as several borehole segments, with a uniform borehole wall boundary condition.
