<p class="MsoNormal">I cannot seem to get any heat out of my GSHP
"well field". Does anyone have a suggestion?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The actual system on paper is a vertical well
field with water to water heat pumps that feed AHU coils,
perimeter fin, and reheat coils.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I've set up the Water to Water GSHP Hybrid
system, following the archive posting of steps:<o:p></o:p></p>
<p class="MsoNormal">1. Create a 2 pipe loop with snap temp. <o:p></o:p></p>
<p class="MsoNormal">2. Create a 'chiller' of the type ' heat
pump' <o:p></o:p></p>
<p class="MsoNormal">2. Create an independent circulation loop of
the type 'lake/well'
<o:p></o:p></p>
<p class="MsoNormal">3. Create a ground loop heat exchanger of the
type 'lake/well'
<o:p></o:p></p>
<p class="MsoNormal">4. Select the GLHX loop for the chiller CW
loop <o:p></o:p></p>
<p class="MsoNormal">5. Assign a custom temperature schedule for
the lake/well ground loop based on a duplicate GSHP model with
vertical well field and water to air heat pumps and an hourly
ground outlet temperature report.<o:p></o:p></p>
<p class="MsoNormal">6. Adjust the default head/pump properties
for the ground loop (i.e. for a closed ground loop no static
head)"<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, the loop does not seem to be heating
(so many unmet hours). (V3.65)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How does eQuest convert the ground loop delta
T to heat? Is it supposed to be using the heat pump chiller? I
have an electric boiler attached to the loop but that just
consumes electricity and when I "turn it off" by putting in
.0001 for capacity, there are thousands of unmet hours. Am I
missing a step? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The normal GSHP loop temps are 110F for
cooling and 30F for heating but for the 2 pipe work around, the
2 pipe loop defaults to 40F for chw and 120 F for hw and the
GSHP loop to 60F chw 45F hw - is this correct? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried to run the same scenario in the 3.65
build 7175 and bootleg 3.70 versions, but came up with the same
result.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also screwed around with the load
management and equipment controls but this did not really seem
to have any effect. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please help!<o:p></o:p></p>
<p class="MsoNormal">Thanks.<o:p></o:p></p>
