<p>Hooman,</p>
<p> Make sure that there is flow through the Type11 when you are
seeing it change the temperature. If flow is zero then the Type
has to set the outlet temperature to something. There have been
some versions of Trnsys that set the outlet temperature to the
inlet temperature (or in the case of a mixer to one of the inlet
temperatures. There have been other versions in which Type11
simply held the last calculated value until flow became non zero
again. Again, this only has to do with the situation when there is
no flow.<br>
</p>
<p> If that does not solve the problem and if you are using v18
then I would recommend you send the project to your distributor
for some help.</p>
<p>kind regards,</p>
<p> David</p>

<p>If you are wanting to simply mix two fluid streams together
use the "Tee Piece" component (11h) rather than the
"Controlled Flow Mixer" component (11d).<o:p></o:p></p>

Figure 1 the outlets of two collectors (CPC 1 and CPC 2)
