Re: [TRNSYS-users] active layer



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

Dear Trnsys users,

I set up an active layer on a wall type (floor heating system) which is
divided in many surfaces (for example a upstair room is adjacent  to two
downstair rooms, so i have two different surfaces on the wall list of the
zone).
Which is the mass flow rate to be given in active layer specification of each
surface? the total one for the floor, to both surfaces, or should I divide the
total mass flow in two part?

thaks in advance
