<p class="MsoNormal"><span style="color:black">I
am modeling a VAV system using water cooled DX air handlers on four of five
floors. 24/7 load spaces use CHW fan coil units and the entire fourth
floor uses chilled water VAV air handler. Each DX VAV has an economizer
coil so hours in the winter when the CW temp is low enough the internal zone
receives free cooling. The entire chilled water loop also has a
water-side economizer so all the chilled water equipment can recieve free
cooling.</span></p>

<p class="MsoNormal"><span style="color:black">As
seen by the elec consumption graphs I'm having a problem with the CW loop
control strategy. Either the loop operates at the commanded setpoint of
85 deg. Which means there is no free cooling. Or when I try to use
OA-Reset the cooling loads during the winter are met via free-cooling but
during the summer the chiller barely runs and the cooling tower tries to meet
the load of the CHW loop.<br>
<br>
I was able to find the way to disable the error caused by condenser water below
65 deg thanks to post from board veterans like Mike TIllou, Steve Gates, John
Albach, and others). I do not know what else to try.<br>
<br>
Thanks,<br>
