<br>
I start with kW/ton ratings at AHRI conditions from the
manufacturer. Those are good inputs into the software. I use
Energy Pro, but I believe most software can take that as input.<br>
<br>
It is theoretically possible to estimate performance with
evaporative pre-coolers if you have reliable effectiveness and
chiller data. <br>
<br>
Most programs will allow VFD or multi-speed pumps as well.<br>

<div>I'm trying to assess possible energy savings from improving
different areas of a chiller plant (cooling towers, adding
free cooling, VFDs, controls). Currently all the information I
have is a snapshot of the chiller plant performance at 2pm
every day of the summer.</div>
<div><br>
</div>
<div>Is there a simple way to evaluate kWh saved? If modelling
is the best option which software is the best for this kind of
analysis?</div>

<div>Thanks for any help,</div>
