Re: [TRNSYS-users] Determination of heat tranfer rate of walls in Type56

[tommaso.toppi@polimi.it]

I'm trying to obtain the heat transfer coefficient, so the problem is similar.
I tried with QCOMI for a surface and dividing it by the temperature  
difference between the surface and the star node, but I found  
non-physical results.

Is there any heat flux I have to subtract to QCOMI before?
What about QABSI? (QCOMI - QABSI) shouldn't be the convective heat flux?

Thank you
