Now I can model it in proper way but when I am comparing results for with <st1:place
w:st="on"><st1:PlaceName w:st="on">Cooling</st1:PlaceName> <st1:PlaceType
w:st="on">Tower</st1:PlaceType></st1:place> 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>
