<p class="MsoNormal">Thanks Hassan <br>
<br>
Now I can model it in proper way but when I am comparing results for with
Cooling Tower and Ground Heat Exchanger for heat Rejection I found Total energy
consumption increases with GHX. I want to share results with all in attached
file, mainly chiller energy consumption increases and pumps decreases. I want
to know why pump power decreases with GHX.<br>

<p class="MsoNormal"><font size="2" color="black" face="Calibri"><span style="font-size: 11pt; line-height: 115%; color: black;">First you need to create
CW loop (I called it GSHP Water Loop) and then create Ground Loop Heat
Exchanger and select the type as Vertical Wells-Sweden G-Function (see below) </span></font></p>

Ground loop instead of using cooling tower with chilled water system. I am
trying to model same in eQUEST, as I select Lake/well as Ground loop heat
exchanger type it model correctly with connection to condenser water loop but
as I select vertical well Sweden G function it removes condenser water loop
connection ask to define circulation loop assignment and also I am not able to
connect it to condenser water loop.</span></font></p>
