Dear TrnSys 
users,
I'm trying to model 
a cooling floor under TrnBuild. I use an active layer with a constant input 
temperature (17°C). I would like to model the effect of a constant fluid flow on 
the building temperature and on the effective cooling power of the floor. In 
order to allow for my constant flow (3.8 kg/h.m²), I use the automatic 
segmentation of the active layer. My model runs all right.
In order to assess 
the cooling power of the floor, I use the surface output n°19 "QCOMI". This 
output is calculated for each segment. My problem is that when I compare the 
QCOMI for each segment, they are really diffrenet. I would have expected similar 
results.
- Is my model 
allright to model a cooling floor ? 
- Is QCOMI the 
correct output to assess the effective cooling power of the floor 
?
- If both previous 
answers are yes, would have any idea of why such a difference between the QCOMI 
of each segment ?
Thank you for your 
help !
