[Equest-users] Deleting a Chiller From a Chilled Water Loop

Wed Aug 12 13:55:15 PDT 2015

The hydronic inputs component tree has multiple such “gotchas,” but as a
general rule within the eQUEST interface you will be fine so long as you
delete things “from the bottom up.”  That is, before deleting a space,
delete the child components starting with the grandkids (i.e.
windows/doors, then surfaces, then the space).  This avoids “orphan”
related issues that will sometimes throw an obvious error and other times
will only rise up to bite you later!

With respect to chiller quantities, pay mind to the inputs highlighted in
the following screen – if you mean to define one of each chiller type,
those should read “1”:

I might also add on first glance you may want, before diving far into
detailed edits, to also revisit your wizard-level zone mapping for the
shell “Telford 1st Floor lobby 2 & Dayc” as it appears the automated
perimeter/core zoning may be having troubles with the shell’s footprint
outline (note the overlapping perimeter/core spaces).  Even if you don’t
mean to get more detailed, a few manual edits to the automated zoning
effort can clear this matter up by adding/deleting a couple vertices:

I hope this helps!  As you’ve likely picked up (but I will reiterate) this
is a relative doozy for a first simulation project.  Consider this job more
of a marathon and less of a sprint: reach out for help and take mental
breaks when you need to so that you’ll reach the finish line!

Often when you delete chillers or other central plant items, you end up
with 'orphan' pumps located at the very bottom of the component tree.
Saving then reloading the file often helps in finding such issues.

Thanks Daric,

I closed the file and reopened and saw the 99 space errors you mentioned.
Interesting thing is I was able to run a report with these errors prior to
deleting the chillers. Go figure. Anyways, I will fix the names and see if
that helps. Yup, big file/project and it's my first time using eQuest. Fun
times.

Jill;

This is a BIG model – dang.

I was able to download and open the model – but I had numerous errors due
to Spaces having the same name [re: 10+ ‘STAIRWAY’ and ‘MECHANICAL ROOM’].
These spaces should be renamed, even its to add a direction [N/S/E/W] or a
number to the end to differentiate them. This has caused me issues in the
past when I get two Spaces with the same name. This also cascades into
issues with the assigned Thermal Zone since it has no way differentiate
between this ‘Stairway’ or that ‘Stairway’.

I’d say step 1 is to correct the above, and then reload the model. This
could be the issue.

An additional area to look at is the ‘Read.log’ file. This file is created
when the model is loaded, and by searching for ‘Error’ in this text file,
you can quickly skip to the issues in the .inp file. I’ve found it more
useful at times than the ‘BDL Error Manager’ interface with eQuest.

On the Chiller issue, my read.log file didn’t show these at all. But it
could have been ‘choked off’ but the errors above.

Let us know what you find.

Thanks,

Good Afternoon,

I am trying to generate the savings of changing out the pumps in the
cooling tower and chiller of the hospital I am modeling. I am out of the
wizard and in detail mode and noticed that four chillers (1a, 1b, 2a, 2b)
were showing up in the component tree instead of just the actual two. I had
no errors in my file and right clicked on chiller 1b & 2b and hit delete.
The warning did say there was a child component but I believe that was the
pump associated with it and hit delete.

Now when I try to run simulation I get "1 Run(s) Terminated Due to Errors"
and can not view the summary report. When I left click the "Check Building
Description" box it says there are no BDL errors. Not sure how to resolve.
I have a saved file with the chillers before they were deleted but have
attached the file with 1b and 2b deleted that I am having problems with and
would greatly appreciate any help. Thanks!
