<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am currently attempting to model several ground source heat pump systems on a single ground loop all in the same cooling plant. Two of the ground source heat pumps have energy recovery and two do not. In my analysis reports I am only
seeing energy usage in “Cooling Equipment – Cooling Mode” for one of the four heat pumps. Is Trace able to model this arrangement? Any tips on how to handle would be greatly appreciated.<b><span style="font-size:10.0pt; font-family:"Arial","sans-serif"; color:black"></span></b></p>
