model in the wizard, then take that to the detailed interface and you can see
how eQuest sets up and connects everything.<o:p></o:p></span></p>

color:#1F497D'>I had to do this earlier this week because I had a heavily
developed model that was already in the detailed interface. I had to
change the system type from air cooled chillers and AHU’s to ground
source heat pumps with a loop and a ground HX. I couldn’t go back
to the wizard because I would lose lots of other valuable inputs.
Therefore, I studied the simple example model in order to see how to set
up everything correctly in my detailed model and it worked. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>One thing I didn’t know is that eQuest uses the “Pkgd
Var Vol Var Temp” system for a WSHP/GSHP system. But, the option
for “WL/GS Ht Pump” is set to “Yes”, the condenser type
is set to “Water Cooled” and the CW Loop is assigned to my “GSHP
Loop”. Previously, I tried using the “Water Loop HP” air
system type and I couldn’t get the program to work, even though that
system seemed like the intuitive air system choice. In my case, I had my
loop and ground HX defined and in place before configuring my air systems so
that I had a loop to assign the air systems to. I would define the loop
first, then the ground HX. Within the ground HX, the “Circulation
Loop Assignment” parameter is where you assign the HX to your loop.<o:p></o:p></span></p>

this has been addressed at some point, but does anyone have experience or
tutorials in setting up ground source heat pump loops in eQuest? I have
been able to set up the ground source heat exchanger, but I'm unsure of the
methods and limitations for linking the ground source loop to the water/water
or water/air heat pump component. Are both situations possible? For
an airside device, would I set up the ground loop, then set up the airside
device and select the particular water source loop with which to link it?</span><o:p></o:p></p>
