<p class=MsoPlainText>Apologies for raking up the past, but I'm trying to model
a chilled beam in EQUEST and have a follow up question. If you use the
Induction unit model (see diagram below), why do you need an OA-from system? Doesn’t
it allow you to run and control outside air within the system?<o:p></o:p></p>

<p class=MsoPlainText>Yes connect the OA system to the dummy zone and the IU or
FC system (using<o:p></o:p></p>
<p class=MsoPlainText>OA-FROM-SYSTEM) to the actual zones.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Provided you set your primary air volumes (the usual
practice) then setting<o:p></o:p></p>
<p class=MsoPlainText>the induction ratio very high (10 is the limit I think)
is inconsequential<o:p></o:p></p>
<p class=MsoPlainText>for a passive chilled beam system. DOE-2.2 doesn't
care about the amount of<o:p></o:p></p>
<p class=MsoPlainText>induced air, it cares about the beam output. I
believe the zone coils /<o:p></o:p></p>
<p class=MsoPlainText>beams will deliver the output needed regardless of the
room to mean wate<o:p></o:p></p>
<p class=MsoPlainText>temperature difference.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thinking this through there are two ways to go about this
depending on your<o:p></o:p></p>
<p class=MsoPlainText>heating configuration:<o:p></o:p></p>
<p class=MsoPlainText>1) Use the IU system only (no OA-FROM-SYSTEM) and use an
outdoor air reset<o:p></o:p></p>
<p class=MsoPlainText>schedule to ge the space humidity control you
desire. The optimal reset<o:p></o:p></p>
<p class=MsoPlainText>schedule is very climate sensitive. You will need
to try a few and you may<o:p></o:p></p>
<p class=MsoPlainText>need to bound the results using cooling from one and
heating from another<o:p></o:p></p>
<p class=MsoPlainText>... This configuration relies on zone heating (baseboards
or other) to<o:p></o:p></p>
<p class=MsoPlainText>maintain space temperatures and thus does not worry about
cold primary air<o:p></o:p></p>
<p class=MsoPlainText>potentially overcooling space sor creating drafts.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>2) Where you want to control the zone supply temperature
above a minimum,<o:p></o:p></p>
<p class=MsoPlainText>and thus place more cooling load onto the beams, then you
need to resort to<o:p></o:p></p>
<p class=MsoPlainText>teh OA-FROM-SYSTEM I described. In this case I have
set the off-coil<o:p></o:p></p>
<p class=MsoPlainText>temperature to a constant (conservative) rather than a
floating off-coil in<o:p></o:p></p>
<p class=MsoPlainText>response to the space humidity. You can't do the
latter without a dummy<o:p></o:p></p>
<p class=MsoPlainText>building that closely mimics space sensible and latent
loads. I then<o:p></o:p></p>
<p class=MsoPlainText>sometimes dump teh hourly results to a spreadsheet (coil
temperatures and<o:p></o:p></p>
<p class=MsoPlainText>outputs and zone humidity ratios) and calculate an
adjustment to adjust the<o:p></o:p></p>
<p class=MsoPlainText>cooling and reheat.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
