Information
This is partial model description of a hygro-thermal wall.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Units.SI.SurfaceCoefficientOfHeatTransfer | alphaIns | 7.692 | Heat transfer coefficient (convection + radiation) inside of the wall |
| Modelica.Units.SI.SurfaceCoefficientOfHeatTransfer | alphaAmb | 25.0 | Heat transfer coefficient (convection + radiation) outside of the wall |
| Modelica.Units.SI.CoefficientOfHeatTransfer | UVal | 1.0/(1.0/alphaIns + sum(constructionData.thickness[i]/constructionData.material[i].lambdaDry for i in 1:constructionData.nLayers) + 1.0/alphaAmb) | U-value of the wall construction under standard conditions |
| Initialization | |||
| Modelica.Units.SI.Temperature[constructionData.nLayers] | T_start | {293.15 for i in 1:constructionData.nLayers} | Start temperature of each layer |
| BuildingSystems.Types.RelativeHumidity[constructionData.nLayers] | phi_start | {0.5 for i in 1:constructionData.nLayers} | Start relative humidity of each layer |
