[Equest-users] Overload problems.. again.

[Osser, Roselin E.]

Hi Kim,

This warning on the PS-D means that the equipment on the loop is undersized to meet the demand.  You should check to make sure that the peak load reported on the PS-D report for each loop can be met by the capacity of the attached boilers or chillers.   If you're allowing the boiler and chiller to size themselves, you can sometimes get this error message if you put a process load directly onto the loop; the equipment won't do a good job of sizing itself properly.

Hi All~

I've been posting about loop overload problem  and still haven't got any responses.

In the archive, some equesters had cast questions regarding overload problems, but they don't seem to get answers either.

It it really that, no one knows how to fix it, or no one had experienced overload problems but us who question about it.

I just want to know why the over load is being shown in the loop report(PS-D),
and any possible approach to fix the overload.

Any advice or a mere comment will be a great help!

Thank you!

Kim
