color:#1F497D'>I suspect your problem might be that your screw chillers are air
cooled. If you look at the documentation (Volume 6) below, the economizer is an
all or nothing deal. If your loads aren’t being satisfied by the
economizer, you will default to the air cooled system, which would zero out
your condenser loop. Where is your project located? If it is in a humid
climate, you might not actually be meeting the entire load this way. <o:p></o:p></span></p>

<p class=MsoNormal>I am trying to model a cooling tower but have not been able
to make it work. I am running the model in 3.63b. The model will run if I
attach the condenser loop directly to one of my chillers, but when I attach the
water economizer to the condenser loop, as instructed in the documentation, I
get an error message that their is no load on the condenser loop.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>

<div>
<p class=MsoNormal>Has anyone had any success getting this type of system to
work? The documentation is light on this topic. Any and all assistance would be
greatly appreciated.<o:p></o:p></p>
