The number of loops is the number of individual pipes that are all
fed from a single manifold. Section 5.2.4.2.3 of the
05-MultizoneBuilding manual covers the "how to define" aspect of
active layers. The flow that you specify is divided evenly between
the pipe loops and that in turn has an effect on the internal heat
transfer coefficient between the pipe wall and the liquid in the
pipe. Section 5.4.4 of the same manual covers the mathematics that
underlie the active layer model. If you haven't found enough detail
or don't find the answers you are looking for in those sections,
please let your distributor know!<br>
best,<br>

<div dir="ltr">Hello,
<div> I am working on TRNSYS 17 and I have a question regarding
the TRNBuild. </div>
<div><br>
</div>
<div>What is meant by "Number of loops" in ACTIVE LAYER
SPECIFICATIONS tab, if under floor heating system is
activated. How do we define it?</div>
<div><br>
</div>
<div>Please let me know if anyone has an idea about it and how
does it affect the flow rate. Since nothing is mentioned about
this in the user -manual, I'm confused about the internal
connections in the flooring.</div>
