Some of the changes that you guys are seeing could also be due to the new DOE2 engine, especially if you had not updated it for a while.<br><br><div class="gmail_quote">On Wed, Jun 3, 2009 at 1:55 PM, Charles Land <span dir="ltr"><<a href="mailto:cland@geo-marine.com">cland@geo-marine.com</a>></span> wrote:<br>

<p><span style="font-size: 10pt; color: navy;">Your input had some relatively unique issues that we have resolved
and will be posting a new release shortly. Here is the summation of
issues:</span></p>
<p><span style="font-size: 10pt; color: navy;"> </span></p>
<ol style="margin-top: 0in;" start="1" type="1">
<li style="color: navy; margin-bottom: 12pt;"><span style="font-size: 10pt;">As identified
below, the ZONE:HMIN-FLOW-RATIO was defaulting to the SYSTEM level
MIN-FLOW-RATIO rather than HMIN-FLOW-RATIO. In your input, you specified
SYSTEM:MIN-FLOW-RATIO = 0.8, but at each zone you specified
ZONE:MIN-FLOW-RATIO = 0.46. The zone HMIN-FLOW-RATIO was then
defaulting to 0.8 rather than “no default”, which would have then been set
at the start of the simulation to 0.46. <br>
<br>
Interim solution: Don’t specify the MIN-FLOW-RATIO at both the SYSTEM and
ZONE level; either is fine, both are not.</span></li>
<li style="color: navy;"><span style="font-size: 10pt;">When the
SYSTEM:SUPPLY-FLOW is specifed, and one or more ZONE:ASSIGNED-FLOWs are
also specified, the outside air requirement for that zone was dropped from
the summation of zone outside air requirements. This causes the
“OUTSIDE AIR RATIO” reported on SV-A to be less than it should be,
resulting in less heating energy.<br>
<br>
Interim solution: Don’t specify SUPPLY-FLOW and ASSIGNED-FLOW
concurrently. Or, don’t specify any zonal outside air requirements,
and instead specify the SYSTEM:MIN-OUTSIDE-AIR</span></li>

<p><span style="font-size: 11pt; color: rgb(31, 73, 125);">I sent this e-mail a few weeks ago in hopes to validate the
accuracy of the new equest 3.63. I have heard back about bugfixes you can
place in your bdl code as well as a pending release. The only problem is
the bug fix is for when your heating and fan energy is increasing. My gas
usage is dropping when running my old file in the new equest. Has anyone
heard anything else about any of the problems (bugs) with 3.63. I am
honestly worried about switching over. Has anyone else still been running
into these problems? </span></p>

<span style="font-size: 10pt;">Jason,</span> <br>
<br>
<span style="font-size: 10pt;">There is a bug
in V3.63 that defaults zone heating minimum flow ratio to 1.00 (technically, I
think it defaults to the system minimum overall supply ratio), rather than the
system heating minimum flow ratio (which defaults to 0.01). This will
cause systems with variable heating air flow to use a lot more fan and heating
energy than expected.</span> <br>
<br>
<span style="font-size: 10pt;">You can either
change all of your zone flows manually or set a user-defined default code
snippet: for the zone heating minimum air flow (or insert this bit of code in
your .inp file).</span> <br>
<br>
<span style="font-size: 10pt;">if
(#P("HMIN-CFM-RATIO") == unused)</span> <br>
<span style="font-size: 10pt;">
then unused</span> <br>
<span style="font-size: 10pt;">
else if (#RV(#P("HMIN-CFM-RATIO")) == 0)</span> <br>
<span style="font-size: 10pt;">
then #P("HMIN-CFM-RATIO")</span> <br>
<span style="font-size: 10pt;">
else no_default</span> <br>
<span style="font-size: 10pt;">
endif</span> <br>
<span style="font-size: 10pt;">
endif</span> <br>
<br>
<br>
<span style="font-size: 10pt;">Hope this
helps,</span> <br>

<span style="font-size: 10pt;">Has anyone
ran any of their old files in the new equest yet. My numbers have
significantly changed. I am working on ECMs and my constant volume
alternative is saving more money than my vav alternative. Is anyone else
having any problems with this. Should I not be running 3.61 file on 3.63?</span>
