functionglassAbsExteriorIrradiationNoShading
Angular and hemispherical absorptance of each glass pane for exterior irradiation without shading
Extends from Buildings.HeatTransfer.Windows.Functions.BaseClasses.partialWindowRadiation (Partial function for window radiation property).
Information
This function computes specular and hemispherical absorptance of each glass pane for exterior irradiation without shading.
It counts the transmittance and reflectance among different panes.
Pane 1 is facing the outside and pane N is facing the room.
Inputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real[3,N,N,HEM,NSta] | traRef (from partialWindowRadiation) | Transmittance and reflectance with exterior irradiation and no shading | |
| Integer | N (from partialGlassRadiation) | Number of glass layers | |
| Integer | NSta (from partialGlassRadiation) | Number of window states for electrochromic windows (set to 1 for regular windows) | |
| Integer | HEM (from partialSingleGlassRadiation) | Index of hemispherical integration |
Outputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real | abs | Angular and hemispherical absorptance of each glass pane for exterior irradiation without shading. Indices: abs[1 to N : ] -> pane 1 to N; abs[ : 1 to HEM] -> angular (1:HEM-1) and hemispherical (HEM) |
