Electrochromic window

Extends from Window (Test model for the window).

Information

This model demonstrates the implementation of a window model. On the left hand side is a model for the combined convective and radiative heat transfer on the outside facing side of the window. In the top middle is the window model, and below is a model that computes the solar radiation balance of the window. Output of the solar radiation balance model are the absorbed solar heat flow rates, which are input to the heat balance models. On the right hand side are models for the inside surface heat balance. As opposed to the outside surface heat balance models, these models are implemented using separate components for the radiative balance and for the convective balance. This has been done to allow separating radiation from convection, which is required when the room model is used with room air heat balance models that use computational fluid dynamics.
