Re: [TRNSYS-users] Radiant Floor System in TYPE 56
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

Dear all,
I'd want to know if is possible to simulate a radiant system with
capillary pipes imposing laminar conditions for the fluid using prebid
4.0. I haven't understood the mean of "number of fluid loops" in active
layers definition. Are the pipes connectded by pipe coil with the same
value of mass flow rate or the mass flow rate is divided by the number of
pipes in the floor? In fact, the aim of my job is to simulate a radiant
system where the pipes are in parallel and the mass flow rate is divided
in every pipe, in accordance with the attached picture.
Any suggest is welcome.
Best regards to all.
