<p class="MsoNormal"><span style="font-size:12.0pt">Travis – sometimes this error can be addressed by putting a nominal process load on the offending loop – say 0.000001 Mbtu/hr, with a minimal schedule.<o:p></o:p></span></p>

<p class="MsoNormal">Hello all:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a system that is using well water direct to the cooling coils (no heat exchanger to protect the cooling coils) at multiple air handlers in the building. I set it up with the condenser water loop tied to a ground water heat exchanger.
This condenser loop then is tied to another heat exchanger on the chilled water loop to the coils. This approach has given me an error on the condenser water loop that it has no design flow. I have been playing with the primary/secondary loop designations,
even putting some made up flow values into the loops/pumps etc. but have had no luck. Any ideas?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to eliminate heat exchangers all together and just model the 50° well water directly into the chilled water loop – any advice on how to do this? I already changed the effectiveness of the heat exchanger to 1.0.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks <o:p></o:p></p>
