would need a component that can be used for diverting return
flow rate from a cooling coil so that part of it goes back to the
cooling source and part is mixed with the inlet flow rate. The idea is
to keep the cooling fluid inlet temperature at its set point. </span></font><font color="#1F497D" face="Calibri,sans-serif"><span style="font-size:11pt" lang="en-US"><b>(Please
see the attachment!).</b></span></font><font color="#1F497D" face="Calibri,sans-serif"><span style="font-size:11pt" lang="en-US"> So in a way you could say that it’s a reverse application for a tempering valve.</span></font></span></font></div>

have tried to implement this combining a flow diverter (Type
11f), a flow mixer (type 11h) and an iterative feedback controller (type
11h). However I it seems to be very difficult to get the controller to
work properly and without convergence (Is it possible at all?).</span></font></span></font></div>

my question is that what would you suggest to be the best
way to do this? Can this be done with the basic TRNSYS components
(e.g.type 11f), or is there a component in some TESS library that is
designed for this kind of situation?</span></font></span></font></div>
