[TRNSYS-users] Type 56 Wall Settings

[Marion Hiller]

Qi Cheng,

the problem you described looks more like a ground coupling modelling.
Due to the total thickness of 3.5 m the heat transfer is two dimensional.
The transfer function approach isn't appropriate for this:
- It models 1-dimensional heat transfer only and
- the time base will be too large in relation to the other dynamic effects inside the building.

I would recommend using a ground coupling model like Type 49 or Types of the TESS libs.

Betreff: [TRNSYS-users] Type 56 Wall Settings

Dear Madam/Sir,

Sorry to disturb you.

I want to construct a wall in Type 56 which consists of 1m heavyweight concrete and 2.5m stone aggregate concrete. But in Type 56, the thickness of wall cannot be exceed 1m.

If possible, could you give me some suggestion.
