Subject: [TRNSYS-users] Active Layer and auto segmentationDear all,
Why is not the button “Divide surface” always present?
I am simulating a radiant wall with “standard” features (pipe spacing 15 cm, pipe ext diameter 2 cm, pipe thickness 2 mm).
Furthermore, I have found no information about how the parameter “number of fluid loops” is taken into account in the mathematical model. Do you have any idea?
Last question: how does TRNSYS calculate the minimum allowed inlet mass flowrate in case of a “number of fluid loops” greater than 1?
Thanks a lot!
With best regards!
Stefano

Dear Younness,
The TRNSYS Volume 1 document steps through a simple TRNSYS simulation. The heat exchanger components are very similar in concept to the other typical TRNSYS components such that it has time independent (constant) parameters, inputs (either variable from another component or a constant input value), and outputs. There is the TRNSYS Mathematical Reference Volume 4 document with information about the heat exchanger models in TRNSYS. There are a few examples with the TESS HVAC Library in the ".\Tess Models\Examples" directory with TESS Heat Exchanger models.
Best regards,
Matt Duffy

Please if any one of you have a "step-by-step" tutorial showing how we can simulate a heat exchanger system (any one) using TRNSYS, I would be grateful if can send it to me or show me the URL of the tutorial.
thanks a lot.
Younness
