<DIV><SPAN class=399204817-11082008><FONT face=Arial size=2>Does anyone have
insight on a relatively easy way to model free-cooling coils on air-cooled
chillers? I thought adding a drycooler might help simulate this, but I
don't even think you can attach a heat-rejection device directly to a chilled
water loop. Is this one of those things that you have to "estimate"
by approximating the total # of available free-cooling hours and
subtracting compressor energy?</FONT></SPAN></DIV>
