[TRNSYS-users] active layer

[David BRADLEY]

Teresa,
   You can treat it either way depending on how the floor heating system 
is piped. My guess is that the two floors would be piped in parallel 
(from the same header) in which case you would want to divide the total 
mass flow into two parts (probably ratio-ed by the areas). If, however, 
the two floors are piped in series (one leading into the next) then you 
would give the full flow to the first floor, then give the full flow to 
the second floor but with its inlet temperature set to the outlet 
temperature of the first floor.
Kind regards,
  David
