<p class=MsoNormal>Hello Equest friends,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am working in the DD Wizard (and trying to not move into
Detailed Mode), building the Proposed and Baseline models for a project that is
in the middle of design. I took the Proposed model file and did a
"Save As" to create the Baseline model, so I know that the two models
are starting out the same. My Proposed HVAC system is a Packaged VAV with
Electric Heat and my Baseline system is a Packaged Heat Pump Constant Volume.
When I only change the system type in the Baseline model from the Proposed Pkgd
VAV to the Constant Vol. HP, my annual energy consumption for cooling reduces
in the Baseline model (I would expect no change), the heating consumption
reduces (this is to be expected), <u>and the fan power goes down in the
baseline</u>. I can't figure out, when I change from a VAV to a Constant
Volume system why the fan power would ever go down. I was hoping to make
up for the HP's better heating efficiency through reduced fan power. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This just doesn't make sense to me. Remember, I'm
still in the DD Wizard and only have limited access to changes. Can
anyone explain this to me and offer advice on how to achieve more predictable
results? Thanks in advance for the help.<o:p></o:p></p>
