recordConstruction
Template record for surface structure: define/order layers from outer to inner
Extends from Modelica.Icons.MaterialProperty (Icon for property classes).
Information
This record may be used to define the structure of constructions (walls).
Typical use and important parameters
Parameter mats should be used to define
the type and thickness of each material layers.
Parameter incLastLay may be used
to define the intended inclination angle
of the last material layer.
This is to check if you correctly connect
models that used this construction since
otherwise the natural convection correlations
may be computed for instance assuming a floor
orientation instead of a ceiling orientation.
Assumption and limitations
Edge effects are neglected. A simple correlation for unventilated cavities is used when modeling an air layer.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | nLay | size(mats, 1) | Number of layers of the construction, including gaps |
| Integer | nGain | size(locGain, 1) | Number of gain heat ports |
| Integer[:] | locGain | {1} | Location of possible embedded system: between layer locGain and layer locGain + 1 |
| IDEAS.Buildings.Data.Interfaces.Material | mats | Array of materials. The last layer is connected to propsBus_a. | |
| Modelica.Units.SI.Angle | incLastLay | IDEAS.Types.Tilt.Other | Set to IDEAS.Types.Tilt.Floor if the last layer of mats is a floor, to .Ceiling if it is a ceiling and to .Other if other. For verification purposes. |
