blockPartialRadiation
Partial model for variables and data used in radiation calculation
Extends from Modelica.Blocks.Icons.Block, Buildings.HeatTransfer.Windows.BaseClasses.RadiationBaseData.
Information
The model calculates solar absorbance on the window. The calculations follow the description in Wetter (2004), Appendix A.4.3.References
