Re: [TRNSYS-users] Type56 - 2 active layers in one wall??

["Arie Kalkman" <a.kalkman@chri.nl>]

Hello Björn,

I asked the same question some time ago, and got a direct reply by Marco, so
it's not in the archive. The idea is to insert a dummy zone with a low
thermal resistance between the two active layers. It worked quite well in my
case, thanks Marco. Schematically, it looks like this:

Zone 1

--------------------------------------

oooooooooooooooooooooo  active layer1

xxxxxxxxxxxxxxxxxxxxxxxxxxx slab

xxxxxxxxxxxxxxxxxxxxxxxxxxx slab

oooooooooooooooooooooo active layer2

--------------------------------------

Zone 2

 

 Which is modeled as:

 

Zone 1

--------------------------------------

oooooooooooooooooooooo  active layer1

xxxxxxxxxxxxxxxxxxxxxxxxxxx slab

---------------------------------------

Fictive zone

---------------------------------------

xxxxxxxxxxxxxxxxxxxxxxxxxxx slab

oooooooooooooooooooooo active layer2

--------------------------------------

Zone 2




Regards, Arie

Hello together!

I'm trying to simulate a two-storied house with floor heating and 
chilled ceiling. This means I need two active layers in the first level 
floor. This isn't permitted by Trnbuild. Does anyone have an idea how to 
get around this limitation?

Thanks for any help!

Björn
