Re: Incident solar flux: calculation of internal & external

Hi!
Of course I can count it manually. But I wanted cleared out whether the model correctly anticipates the window. That does not seem to be possible, that's too bad.
For the evaluation, I could have used it very well. Especially for the presentation of results.
Thank you.

Re: Incident solar flux: calculation of internal & external

Hi there!

Good idea, but I think we misunderstand each other ...

So you think that the internal solar irradiation is the diffuse reflection of the other internal surfaces? That could be very possible. ...
It helps me but unfortunately not. To check the function of the window structure I am looking ...

Incident solar flux: calculation of internal & external

Dear all!

Could someone help me with the difference between external and internal incident solar flux at surface variables in VISTA.

The external incident solar flux is the sum of direct and diffuse solar radiation. That is easy.
But what is the internal incident solar flux? I thought, it is the ...

Re: read out of supply air temperature controlled by profile

:idea:
ok ok. The formula system need it very very simple and bit by bit.
I try somehing like that:
(to<20)& (20<ta<=26)
But my results dosen't look nonsatisfying. So I try a lot to find the reason. In the end I split the formula to:
(to<20)& (20<ta)&(ta<=26)
and now my results looks like I ...

read out of supply air temperature controlled by profile

Hello!

(I hope, that is the right place here)

In my simulation model I use the auxiliary ventilation for fresh air. The temperature of the supply air of the Auxiliary ventilation system I controlled with a temperature profile, wich depends on room air temperature and the outside air temperature ...
