[TRNSYS-users] use of active layer in expert mode & which Rx calculation is used

Dear TRNSYS users,

 

I am trying to get a deeper understanding in the active layer trnsys
model and I have therefore 2 questions:

-          I am interested in the use of the active layer "expert mode"
that can allow me to simulate an active layer performance of a "real
component" of which I would get the "equivalent heat transfer
coefficient" by lab testing. Unfortunately I haven't found yet in the
manual what this coefficient is and how it is used in the TRNSYS
calculation. Do you have any idea?

-          From the mathematical type56 references I understood that
different formulas are used to calculate the Rx resistance depending on
the kind of active layer (ratio dx/delta). Is this check automatically
implemented in the type  and therefore depending on dx/delta trnsys uses
different Rx formulas?

 

Thanks a lot

Stefano
