<p>Janeet,</p>
<p> Type88 and 660 are mathematically equivalent. In addition to
the internal/external controls options I believe that Type660
allows you define multiple "zones" that are adjacent to one
another. Yes, feeding cold air into the ventilation inputs would
be a very simplified equivalency to modeling a temperature level
control building.</p>
<p> I would recommend using Type508 as a cooling coil model if
possible and I would strongly recommend not using Type32. The
others all have features that might (or might not) be useful in
your particular circumstance so I'd recommend having a read
through the documentation on each.</p>
<p>kind regards,</p>
<p> David</p>

</div>
<div>Currently working on a project to simulate an absorption
chiller feeding chilled water to 2 fan coil units which inturn
control the temperatures of 2 zones-feeding the ventilation
temp and flow rate. For comparison purposes, have set up the
simple building loads using type 88 and type 660 and plan to
include a temperature level control on the FCU.</div>
<div><br>
</div>
<div>1. What is the difference between the type 88 and type 660
apart from the internal conditioning equipment control. Would
HVAC equipment feeding cold vent air input be equivalent to a
temperature level control for the building?</div>
<div><br>
</div>
<div>2. Please advise on the differences amongst the various
cooling coils - type 32, type 52, type 508, type 697, type
752. Which would be the most suitable type for the given
application?</div>
<div><br>
</div>
<div>Thank you for your time in advance.<br>
