[TRNSYS-users] Radiant Floor System in TYPE 56

[David Bradley]

Dear Roberto,
   It is my understanding that the "number of loops" indicates the number 
of parallel branches of piping that pass through the floor and that the 
total mass flow rate specified is divided equally among the number of loops 
that you have specified. I belive also that the empirical correlation used 
in the Type56 active layers was developed using various "typical" piping 
layouts. That might include perimeter zones and core zones, it might 
include your "straight through" configuration as well. If you want to use a 
radiant floor model that allows you to specify the path of pipes through 
the floor, you might look at Types701, 703, and 705 in the TESS Ground 
Coupling library.
Kind regards,
  David
