Anand,
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!
best,
David
