.Buildings.HeatTransfer.Windows.BaseClasses.CenterOfGlass

Model for center of glass of a window construction

Information

This is a model for the heat transfer through the center of the glass. The properties of the glazing system is defined by the parameter glaSys. The model contains these main component models:

an array of models glass for the heat conduction and the infrared radiative heat balance of the glass layers. There can be an arbitrary number of glass layers, which are all modeled using instances of Buildings.HeatTransfer.Windows.BaseClasses.GlassLayer.
an array of models gas for the gas layers. There is one model of a gas layer between each window panes. The gas layers are modeled using instances of Buildings.HeatTransfer.Windows.BaseClasses.GasConvection.

Note that this model does not compute heat conduction through the frame and it does not model the convective heat transfer at the exterior and interior surface. These models are implemented in Buildings.HeatTransfer.Windows.Window, Buildings.HeatTransfer.Windows.ExteriorHeatTransfer, and Buildings.HeatTransfer.Windows.InteriorHeatTransferConvective.
