<p class=MsoNormal>If a building less than 3 floors has an air handler that
serves multiple spaces with a capacity of X for the proposed model, then it
will require an hvac system type packaged single zone. <o:p></o:p></p>
<p class=MsoNormal>Would it be correct then to provide a PSZ for each zone
modeled? If so how should the capacities in the baseline be broken up?
Take the proposed capacity and proportion it for each zone based on size,
loads, etc.. Then multiply capacities by 1.15 and 1.25 to get a baseline capacity
for each system? This doesn’t account for supply air volumes.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Or how about a residential high rise? The baseline
hvac system type would be PTAC’s. Consider that each building wing
is modeled as a large zone ( not a zone for every room ). When a PTAC was
made to serve this large zone it did not do so well but I did not take much
time investigating because I did not want to waste time on it. If the
parameters are set correctly, a PTAC can be able to condition a zone no matter
the size?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Has anyone had these questions before? The archives
and user’s manual do not provide much insight.<o:p></o:p></p>
