[Bldg-sim] error message: LOOP has zero flow- ABORTING-- Pleasehelp!

[Brandon Nichols]

Hi Linda,
 
Check to be certain that there  exists terminal equipment in your
project containing hydronic heating coils which are actually attached to
the loop in question -- Hot Water Loop B.   An easy way to check this is
to look at the 'Waterside HVAC' tree --  I'll bet you don't see any
systems under the loop in question.
 
Perhaps are all attached to Hot Water Loop A, or the ones you think that
are attached to Loop B have furnaces instead of hydronic heating coils.
 
The error you're getting essentially indicates zero demand for heating
hot water on the loop.
 
HTH...

To All:

 

Thanks to everyone who has helped me with previous questions.  I am
fairly new at energy simulation and I have learned a lot so far from
just getting emails off this listserve-

 

I am getting an eQUest error message: LOOP has zero flow- ABORTING.  And
a message after wards:

"Errors during HVAC simulation setup or design calculations. See .sim
file for details. Terminating Run."

I cannot find this .sim file...

 

I have eQuest autosizing my boilers, chillers and pump GPM's.  In the
detailed data output report, the error message says:

***ERROR****************************************************************
*******

             Loop: Hot Water Loop B                 has zero design
flow.

             Check input for consistency, or specify design loads.

 

If anyone's had this experience or has a solution, I'd really appreciate
your help!

 

Thanks!
