[Equest-users] eQUEST unconditioned spaces

[Nick Caton]

Hi John,

 

My perceptive powers are not the greatest, as my wife will assure you,
but I'm failing to see the reason to get any feathers need to be hackled
here (I did miss your reply, perhaps it wasn't copied to the list?)....

 

The reality that DOE2 has a "no child-zone left behind act" of sorts is
just the nature of the beast, and nobody is arguing that's unintuitive -
it's simply something we have to learn as we become familiar with the
engine.  I don't know that I'd expect this issue to be resolved in the
next major update as it's something a user can work around (unlike some
other more pertinent issues), as Dakota is plainly demonstrating with
his (typically) thorough response.

 

Everyone is here to help each other, rest assured (^_^)b, those who
aren't don't stick around long, and Dakota's certainly been around for
awhile!  If you have a "more correct" or otherwise better solution to
handling unconditioned zones before or after the wizards, I would
personally like to know also - I do the same as Dakota.  I understand
others simply ignore the zone grouping wizard screens altogether (though
I find them to be quite a time-saver), so his inclusion of "simply do
this" in detailed is very appropriate to the group at large...

 

Wishing everyone a safe and happy weekend,

 

~Nick

Maybe I was too vague in my reply.

 

I, too, was hoping for some insight into this particular issue.

 

While I do believe this to be a software (developer) oversight, I also
believe that any offered solution(s) to such a 'problem' could be
handled with slightly more dignity; perhaps even some humility!

 

It is more likely that 'this' is a software issue more than anything
else.  Hopefully this, and many other issues, will have been addressed
in '3.6.4'!

 

It makes absolutely no sense to me to assign a system to 'unconditioned
space' that is being used to 'condition', condition space. Since every
'space', or zone requires the assignment of a specific mechanical
system, then wouldn't it be likely [as in the 'real world' vs. our
'virtual' one, be equipped with 'NO" system since it is 'NOT'
conditioned, versus an 'operable' system that supplies conditioning to a
space that requires such?  

 

While it agreed that all zone 'must belong to a system', I'm not
convinced that your [emphatic] solution employs the ideal method for
addressing such an issue.  It seems to me that you're placing her back
to the same point in which she came to discover such a unique condition.


 

Looking forward to a legitimate response!

 

Sincerely--

John

Amber,

 

If I'm following your description, you must be specifying the
unconditioned zone in Shell Wizard/Screen 2/Zone Characteristics button.
Then you're obviously specifying system-per-floor in the HVAC wizard.
This sounds like it should work, but what is happening is Shell
Wizard/Screen 14 settings are trumping Shell Wizard/Screen 2.  There are
two solutions:

 

1)      Simply change the zones to unconditioned in the detailed
interface.

2)      Create a new zone group in Shell Wizard/Screen 14.  Assign the
unconditioned zones to this group, and then make sure the "Conditioned"
check box is not checked.  Assign the group to whatever system makes
sense and move on (making sure that at least one conditioned zone group
is also assigned to that system).  All zones have to belong to a system,
but if they're unconditioned their parent system is irrelevant.  This
method is only slightly longer than the one above, but it lets you stay
in the wizard.

 

If you try to leave an unconditioned "on its own", which I interpret as
being assigned to its own single-zone system, you'll get an error saying
every system has to have at least one conditioned zone.  Let me know if
I have misunderstood you.

 

Error! Filename not specified.

What is the best way to handle unconditioned spaces in eQUEST?  Right
now, I am zoning it separate and calling it unconditioned in the WIZARD.
Then, when I assign systems, I am putting the unconditioned zone in a
system with a conditioned space and saying " one system per floor".  Is
this the proper way to do it?

 

I have tried just leaving the zone as unconditioned and on its own, but
then when I do the "permit submittal" calculation it still asks for the
fan flow and cooling capacity for that zone.
