Hi everyone,
I’m working
on a multi-zone building (type 56) model with TRNSYS18 and I want to use the Moisture
Capacitance Model (Buffer Storage Humidity Model). To do this, I have to define
6 parameters: Ksurf, Kdeep, Msurf, Mdeep, Bsurf and Bdeep for every thermal
zone.
There are many questions about this on the mailinglist but not many answers. I
listed some questions about the Buffer Storage
Example (TRNSYS documentation) below :
1- When calculating Mdeep, why the thickness of every material i is not double in
the calculation of Mi as it is for the calculation of Msurf ?
(https://www.mail-archive.com/trnsys-users@engr.wisc.edu/msg01911.html)
2- When calculating
Mdeep, they do consider the concrete from ceiling and ground floor, but there's some information missing in the example to explain Mconcrete = 175kg. For this calculation should I use the thinkness
and area of concrete from floor and ceiling?
3- When
calculating Bdeep, the value of A is 50m^2, wich is the wall/gypsum area. Floor
and ceiling area are neglected?
4- Someone know a good link or reference about this calculation?
Thank you very much,
