Re: [TRNSYS-users] double active layer

[David Bradley <bradley@tess-inc.com>]

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
