Hi, Ben

 

I have tried type60f_2 for such a system.  But, the convergence for the calculation of UA and LMTD is always a problem.

 

Thanks!

Subject: [TRNSYS-users] Thermal Store model with internal HE coils

I am studying at Loughborough University in
the UK and want to model an existing solar thermal system with a specific
thermal store.

The thermal store has an internal heat exchanging coil at
the bottom for the solar input and an internal heat exchanging coil at the top
for the indirect HW output.  There doesn't seem to be a standard model for
a store with internal heat exchangers for input/output.

Does anyone know
of any existing models for this setup?

Many thanks,

Ben
