[TRNSYS-users] Thermosiphon module solar water heater

[Chuck willis <chuckmw@gmail.com>]

Hello,

I am gathering information on a thermosiphon solar water heater system on TRNsys (and TRNed if necessary) and trying to build a model.

 

The main problem is that the T° coming out of the heat exchanger (and into the solar heated water tank) is unknown and therefore might require a loop with a random initial value and many iterations.

 

Is this really necessary, would anyone happen to have a rough draft of this kind of model or something relatively close?

 

Thank you very much for any help at all
