<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My question involves the use of a water-side economizer for
achieving “free cooling” during the off peak months. Has
anyone been able to gain the benefits from this system? I believe the
source of my troubles is in the control of the CHW temperature in the Condenser
Loop. When looking at the hourly reports, I find that the air to water
delta T never exceeds the limit defined in the definition of the water-side
economizer. Is there some type of temperature control method for the
condenser water that I am not using? </span></font></p>
