Re: [TRNSYS-users] about the buffer storage example in the help document <06-MultizoneBuilding>

[Volker Huckemann <volker@igs.bau.tu-bs.de>]

Dear Yujun,

Seems that we are working on the same topics.

The depth of the surface buffer is 3mm because they use only half of the gypsum layer as surface storage. The other part is taken to the deep storage, which contains out of two materials this way.  Thinking of a kind of 'moisture node' this is located in the middle of surface storage.
Actually I can't say a thing about the concrete..

If you have only one layer it should work like the example above. You choose (*) a depth, which affects the moisture balance in your Room in the time step your simulation is based on....this depth defines the surface storage. The Rest is deep storage.

(*) Has anyone literature about the affecting depth in relation to time an materials?
Where can I find more k- values than the ones in the Trnsys manual?

Best regards

Volker Huckemann

Dears users,
I can't understand something in the buffer storage example of the help document <06-MultizoneBuilding>.
Firstly, why the depth of surface buffer is d=3mm?
Then, How to calculate the mass of concrete because there is no description about its depth?
Finaly, if I have just one layer <clay brick> with its depth of  5cm, how to give the value of  Kdeep and the depth of surface buffer?
Thanks in advance
