Dear TRNSYS users,
I want to analyze the thermal behaviour of a
dwelling with floor heating in detail. Attatched is a drawing of
the floor construction. The time-base is set by 1 hour by
default. I would like to set this time-base to a lower value (eg
15 minutes or less) to be able to analyse the reaction to change
in occupancy with accordingly changing ventilation, heating
setpoint and internal gain. However, the high thermla mass and
high insulation value doesn't allow me to because the stability
criteria are not fullfilled. ("Error creating the wall transfer
coefficients: Stability criteria not fullfilled"). In a previous
thread of the forum (
http://lists.onebuilding.org/pipermail/trnsys-users-onebuilding.org/2012-November/024387.html
) I read that there is a "trick" for this. You can devide one
layer in the ground floor (e.g. the concrete slab) with an
active layer. However, if I try I get the message that only
one active layer is allowed. Is there another way to tackle
this problem?
Kind regards,
