David,
thanks for the advice. But can I take e.g. windows into account with
these models? Now I model my whole geometric zone with Google SketchUp
using the Trnsys3d plug-in.
Greets,
Ole

Ole,
To add to what Jean Marais said, by including the wall capacitance
in the zone and making only resistive walls you are turning Type56
into something resembling a lumped capacitance model and are no
longer taking advantage of there being any difference between the air
temperature and the surface temperatures. If that is the kind of
model that you want to use then there are some actual lumped
capacitance building models either as a single zone model the
standard library (Type88) or as a multizone model in the TESS Loads
and Structures library (Types 759 and 660)
best,
David

Dear all,
I'm trying to model a building zone in TRNBuild. The store capacity
is specified by 90 Wh/(m²*K). Unfortunately there is no information
about the single store capacities (e.g. walls, furniture,...). Now
my idea was to just model the zone with massless walls and to add
the whole store capacity to the capacity in TRNBuild (normally the
wall capacity is not valued in this parameter). Normally I don't see
any problems regarding to this way of calculation, becauce I only
use the absolute value of the capacity. Do you see any problems in
doing this?
Thanks and greets,
Ole
