Hi ,
In my simulation I'm using tank Type 60 with internal heat exchanger. So I wanted to evaluate the influence of the HX area on the solar fraction and collector efficiency but with keeping all parameters constant and only changing the HX area and length I keep getting exactly the same solar fraction and same amount of HX energy transferred in the tank even if the HX areas are double in difference between the two simulations.
Any explanation regarding this?
Thank you
Kind regards
Martin
