[TRNSYS-users] double active layer

[David Bradley]

Arie,
   I had to do something similar because I had a zone with an active layer 
that sits on top of two zones below. That meant that I have two "floors" in 
my zone above, one adjacent to each of the zones below. I defined an active 
layer for each of the two floors and added Type56 INPUTS for the inlet mass 
flow rate and temperature to each of the two floors and added Type56 
OUTPUTS for the outlet temperature. In the .dck, I have a flow splitter 
that divides my full mass flow appropriately between the two floors and on 
the output side, I have a flow mixer. I am sure that this does not 
perfectly model the reality of the floor in the actual building since as 
far as the simulation is concerned, there is no heat transferred directly 
between the two floor slabs and in reality of course there would be. 
However, that solution has given me no problems as far as the simulation is 
concerned and all my energy flows look reasonable so I think it is a decent 
approximation. If anyone thinks otherwise, I would be happy to know.
Kind regards,
  David
