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

• Modelica.Blocks.Math.Gain
• Modelica.Thermal.HeatTransfer.Sources.PrescribedHeatFlow

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.
