<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></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"><o:p></o:p></span></b></p>
