going on. I would check the run hours for your chiller to make sure it is
picking up part of the cooling load. Also, it’s a bit strange that your
building needs no heat. If you want to send your input file, I can take a
look at it.<o:p></o:p></span></p>

<p><span style='font-family:"Calibri","sans-serif"'>I’m trying to model a
hot water loop</span> <span style='font-family:"Calibri","sans-serif"'>that’s
being heated entirely by a heat recovery chiller (htrec) and supplying heating
to a VAV</span> <span style='font-family:"Calibri","sans-serif"'>system.
I’d like to utilize</span> <span style='font-family:"Calibri","sans-serif"'>condenser</span>
<span style='font-family:"Calibri","sans-serif"'>heat prior to rejection to the
dry coolers (I have a large cooling load year around). The trouble is, even
though it appears like it is set up correctly,</span> <span style='font-family:
"Calibri","sans-serif"'>the system doesn’t want to reject ANY heat to the</span>
<span style='font-family:"Calibri","sans-serif"'>HW</span> <span
style='font-family:"Calibri","sans-serif"'>loop.</span> <span style='font-family:
"Calibri","sans-serif"'>When I just created the loop and ran a simulation,
eQuest gave me an error saying I had no primary heat source on the HW loop.</span>
<span style='font-family:"Calibri","sans-serif"'>I tried adding a dummy boiler
with virtually no capacity, and that got rid of the error and allowed me to
run, but I still had no heat going to my HW loop. </span><o:p></o:p></p>
<p><span style='font-family:"Calibri","sans-serif"'>Has anyone had</span> <span
style='font-family:"Calibri","sans-serif"'>success with this?</span> <span
style='font-family:"Calibri","sans-serif"'>When reading the DOE2.2 dictionary,
it appears this is exactly what the htrec chiller</span> <span

change makes any difference.</span> <span style='font-family:"Calibri","sans-serif"'>If
