[TRNSYS-users] Question regarding Active layer

[David BRADLEY]

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
