Extends from Modelica.Blocks.Interfaces.BlockIcon.

Information

This model computes in a global fashion, how much of the solar input gets absorbed by the glass panes, how much gets transmitted through, and how much gets reflected.

Since the glass panes have many different orientations, a physical model would be rather computation intensive. Thus, the model goes another route. It estimaes the three quantities globally and on average. 

Parameters:

  alph:  Portion of absorbed power (default value = 0.2)

  tau:   Portion of transmitted power (default value = 0.6)

  refl:  Portion of reflected power (default value = 1 - alph - tau)
