<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I was hoping for some help in trying to troubleshoot a
problem with my current model. I’ve spent hours trying to figure
this out, and all I’ve succeeded in doing is getting angry!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve got a WSHP loop set up with a cooling tower and
boiler, and I have a number of WSHPs as systems. For whatever reason, the
BDL file says I have no cooling equipment installed. And when I run the
model, I show no cooling energy used. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve gone as far as to run a new wizard model with the
same system, and copy everything over to my model, but even that doesn’t
work. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If I change my cooling tower to one with a heat exchanger, I
actually get a “HT-EXCH Convergence Error”, and the .SIM file seems
to indicate that the loop temperature keeps going up and eventually shuts off
the associated systems.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Not sure what else to do…it would seem that there is a
problem with my cooling tower, but even when I copy over the cooling tower,
heat exchanger, pumps, control sequence, etc from a functioning Wizard model,
it still doesn’t work.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If anyone has time, I’ve attached the .inp and .pd2
files. I appreciate any help!<o:p></o:p></p>
