Description
Hi guys,
I stumbled across weird IR emissivity values, so I thought I'd take the opportunity to create my first GitHub issue. As I usually don't work with GitHub, I don't really now the usual workflow. Hope this is the right thing to do :)
What is the problem?
- Inner IR emissivity values become very high (>> 1)
- equations in TEASER/teaser/logic/buildingobjects/calculation seem to be wrong. Examples (there are other similar lines):
-
three_element line 791-797
self.ir_emissivity_inner_iw = ( sum(in_wall.layer[0].material.ir_emissivity * in_wall.area for in_wall in self.thermal_zone.inner_walls) + sum(floor.layer[0].material.ir_emissivity * floor.area for floor in self.thermal_zone.floors) + sum(ceiling.layer[0].material.ir_emissivity * ceiling.area for ceiling in self.thermal_zone.ceilings) / self.area_iw)
should be
self.ir_emissivity_inner_iw = (( sum(in_wall.layer[0].material.ir_emissivity * in_wall.area for in_wall in self.thermal_zone.inner_walls) + sum(floor.layer[0].material.ir_emissivity * floor.area for floor in self.thermal_zone.floors) + sum(ceiling.layer[0].material.ir_emissivity * ceiling.area for ceiling in self.thermal_zone.ceilings) / self.area_iw
-
four_element line 759-761
self.ir_emissivity_inner_ow = ( (sum(out_wall.layer[0].material.ir_emissivity * out_wall.area for out_wall in self.thermal_zone.outer_walls)))
should be
self.ir_emissivity_inner_ow = ( (sum(out_wall.layer[0].material.ir_emissivity * out_wall.area for out_wall in self.thermal_zone.outer_walls)) / self.area_ow)

Why do we want to solve it?
- I think the values are not needed for export, but wrong equations should be corrected anyway. Sorry if I got something wrong and these are intentional values ;)
How do we want to solve it?
- Have a look at all IR emissivity equations in the calculation folder and correct them if necessary
