Thermal properties of solids with heat storage

Extends from Buildings.HeatTransfer.Data.BaseClasses.Material (Thermal properties of materials w/o storage).

Information

Generic record for solid materials. The material is characterized by its thermal conductivity, mass density and specific heat capacity.

Type	Name	Default	Description
Modelica.Units.SI.Length	x (from Material)		Material thickness
Modelica.Units.SI.ThermalConductivity	k (from Material)		Thermal conductivity
Modelica.Units.SI.SpecificHeatCapacity	c (from Material)		Specific heat capacity
Modelica.Units.SI.Density	d (from Material)		Mass density
Real	R (from Material)		Thermal resistance of a unit area of material
Integer	nStaRef (from Material)	3	Number of state variables in a reference material of 0.2 m concrete
Boolean	steadyState (from Material)	(c < Modelica.Constants.eps or d < Modelica.Constants.eps)	Flag, if true, then material is computed using steady-state heat conduction
Boolean	ensureMonotonicity (from Material)	false	Set to true to force derivatives dT/du to be monotone
Advanced
Integer	nSta (from Material)	max(1, integer(ceil(nStaReal)))	Actual number of state variables in material
Real	piRef (from Material)	331.4	Ratio x/sqrt(alpha) for reference material of 0.2 m concrete
Real	piMat (from Material)	if steadyState then piRef else xsqrt(cd/k)	Ratio x/sqrt(alpha)
Real	nStaReal (from Material)	nStaRef*piMat/piRef	Number of states as a real number
Properties for phase change material
Modelica.Units.SI.Temperature	TSol (from Material)		Solidus temperature, used only for PCM.
Modelica.Units.SI.Temperature	TLiq (from Material)		Liquidus temperature, used only for PCM
Modelica.Units.SI.SpecificInternalEnergy	LHea (from Material)		Latent heat of phase change
Boolean	phasechange (from Material)	false	Flag, true if the material is a phase change material
