<p class=MsoNormal>Hello All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My first post to bldg-sim, I have learned a great deal from
your emails.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to wrap up an eQuest model of a school that is
using water source heat pumps (located in Georgia). The building is
connecting to a campus condenser water loop, so there is no heat rejection
system that is actually part of the project, but I have to include something in
eQuest, which I have modeled as a cooling tower and variable speed pump.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am running in to issues with no heating or cooling energy being
reported in the BEPS report, and 94% of hours outside throttling range. I
have tried several different types of HVAC systems (pkgd single zone, water
loop HP, pkgd var vol var temp) all with condenser type as “water cooled”
(except for water loop hp which doesn’t allow you to pick a condenser
type). I have set my circulation loop for condenser water to loop type “condenser
water” and also tried loop type “Water Loop HP” which no
success. When I use “Water Loop HP” I get an error message “Loop:
WLHP water loop has no primary heating equipment.”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On my HVAC systems “heating – coil capacity”
display I have heat source set to “heat pump” and zone heat source
as “not installed”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas? A bad combination of system type and heat
rejection maybe? I have tried all combinations that I can think of.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for taking a look,<o:p></o:p></p>
