modelSimpleHouse2
Extends from SimpleHouse1.
Information
The window has a surface area of 2 m2. In this simple model we will therefore assume that two times the outdoor solar irradiance is injected as heat onto the inside of the wall.
Required models
Connection instructions
To be able to use the value of the outdoor solar irradiance
you will need to access the weather data reader.
To do this, make a connection to the weaBus.
In the dialog box, select HDirNor,
which is the direct solar irradiance on a surface of 1 m2,
perpendicular to the sun rays.
Set the gain factor k to 2,
in order to get the solar irradiance through the window of 2 m2.
Make a connection with the PrescribedHeatFlow as well.
This block makes the connection between the heat flow from the gain, represented as a real value,
and a heat port that is compatible with the connectors of the thermal capacitance and resistance.
Reference result
The result with and without the window model is plotted in the figure below.
