<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=960560713-27022008>As I
know, the current version of eQUEST cannot simulate hybrid GSHP system that has
both boiler and cooling tower coupled with GHX. Although a hybrid GSHP
system with cooling tower only can be set up and run with eQUEST, but
the modeling algorithm for this kind of HGSHP is not flexible enough to
simulate a real HGSHP. The challenging task is to determine how to distribute
the loads and flow rate to GHX and the cooling tower. </SPAN></FONT></DIV>

<P><SPAN lang=en-us><FONT face=Arial size=2>Hello All,</FONT></SPAN> </P>
<P><SPAN lang=en-us><FONT face=Arial size=2>I am trying to model a hybrid
ground source heat pump system (boiler and fluid cooler). Does anyone
know how to do this using eQuest?? I have created the GLHX and attached
a fluid cooler and a boiler, however eQuest will not run the simulation with
the boiler attached to the loop. If anyone has experience with this type
of simulation I would any help that you can offer.
Thanks</FONT></SPAN><SPAN lang=zu></SPAN></P>
