Buildings.Fluid.Geothermal.Borefields.Data.Filling

Collection of records of filling data

Information

This package contains data records for use with ground heat exchanger models in Buildings.Fluid.Geothermal.Borefields. The filling data records contain the heat transfer properties of the borehole filling material.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).

Parameters

Type	Name	Default	Description
ThermalConductivity	kFil	1.15	Thermal conductivity of the borehole filling material [W/(m.K)]
SpecificHeatCapacity	cFil	800	Specific heat capacity of the borehole filling material [J/(kg.K)]
Density	dFil	1600	Density of the borehole filling material [kg/m3]
Boolean	steadyState	(cFil < Modelica.Constants.e...	Flag, if true, then material is computed using steady-state heat conduction
