[TRNSYS-users] The necessity of using pipes in TRNSYS models

[Amir Nashed]

Dear TRNSYS users

I am currently trying to model an application using solar collectors to
heat water and i realized that when i put pipes in the solar collector
loop, i get strange output water temperatures (very low values).

So what i did is that i isolated the solar collector loop and modeled it by
itself and the same problem occurs unless i use very small pipes in terms
of size.

But if i used a small pipe size i sometimes get the warning that the flow
rate the pipe during at least one component was greater than the capacity
of the pipe.

has anyone faced trouble with the pipes before? And is using pipes in the
model needed from the first place in terms of the model stability?

Thank you
