Default inner convection coefficients #680
Comments
We defined the upward and downward coefficients similar, because we can't determine if the heat flow is upwards or downwards. This depends on the temperature of the adjacent environment, e.g. ambient or another thermal zone. So a roof can have a downwards oriented heat flow, if the room above is heated to a higher temperature. Anyway, we never found a good solution to handle this, looking forward to your approach! :-) |
That definitely does makes sense. However, if one assumes the archetypes e.g. of TABULA are defined for "winter conditions", the simulation results are not consistent with them regarding "summer conditions" in the current implementation anyway, right? If that is the case, I would say changing the "inner convection" attributes of the archetype coefficients to 0.7/2.5/5.0 and adjust the layers would be "more right" (but would not really have an impact on simulation results). Nevertheless, your comment makes it an AixLib issue rather than a TEASER issue because a solution would imho require All in all, a rather complicated solution for a problem with a probably very low positive impact on the results, or even a negative impact because calculation times will be longer. |
