Buildings.Fluid.Geothermal.Borefields.Data.Soil

Collection of records of soil data

Information

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

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

Buildings.Fluid.Geothermal.Borefields.Data.Soil.SandStone

Soil data record of sandstone heat transfer properties

Information

This soil data record contains the heat transfer properties of sandstone.

Extends from Buildings.Fluid.Geothermal.Borefields.Data.Soil.Template (Template for soil data records).

Parameters

Type	Name	Default	Description
ThermalConductivity	kSoi	2.5	Thermal conductivity of the soil material [W/(m.K)]
SpecificHeatCapacity	cSoi	1200	Specific heat capacity of the soil material [J/(kg.K)]
Density	dSoi	1800	Density of the soil material [kg/m3]
Boolean	steadyState	(cSoi < Modelica.Constants.e...	Flag, if true, then material is computed using steady-state heat conduction
