you create a heat pump system using eQUEST wizard, in the first screen of the
wizard system (after you specifying both cooling and heating equipment as "DX
Coil"), an additional input entry will appear and ask you specify the source
of the heat pump. The available options include "Air", "Water Loop", and
"Ground Loop". When "Water Loop" is selected, the HVAC system will be defined
a water loop heat pump (WLHP) system (with boiler and cooling tower); When
"Ground Loop" is selected, the HVAC system will be defined as a ground source
heat pump (GSHP) system that uses water-to-air heat pumps connected to a
common (water) loop and a vertical borehole field as heat sink and
source.</FONT></SPAN></DIV>

PVVT is used to simulate the air side of a water-to-air heat pump so that it
can account for the recent developments of water-to-air heat pump, such as the
usage of staged compressor, variable speed fan, etc. If the WLHP/GSHP is
created with the eQUEST wizard, parameters associated with the PVVT system
will be automatically set for constant air flow, and default WLHP/GSHP heat
pump performance curves will be used. The default curves are normalized at the
ARI rating conditions for "ground loop" application (77F EFT for cooling and
32F EFT for heating). If the WSHP/GSHP is created in detailed mode, at this
version of eQUEST, the user has to adjust the parameters of PVVT to
fit for the specific heat pumps being simulated. I've listed some
necessary adjustments for the parameters of PVVT in my earlier post to the
topic "Gshp in detailed edit mode".</FONT></SPAN></DIV>

a performance data/curve library for all the water-to-air heat pumps of a

[BLDG-SIM] Trouble with Heat Pumps (eQuest)<BR><BR></FONT></DIV>
<DIV>Thanks for all the responses. I think I figured it out:</DIV>
<DIV> </DIV>
<DIV>When you choose "WLHP" in the eQuest Wizard, it creates a PVVT system
with a GSHP. The curve used to adjust HIR is based on a few data
points, and did not perform very well at the temperatures I was using.
A straight HP system selected in detailed edit mode did much better. I
now realize that this is because the HIR curve was better for my
purposes. I have now created curves based on the heat pumps spec'd for
this job and the numbers are making more sense. </DIV>
<DIV> </DIV>
<DIV>Thanks again for all the repsonses, thought I'd let everyone know,
especially because PVVT is what is selected when you create a WLHP system
with the wizard, and may need some detailed data edit tweaking.</DIV>

<DIV>I'm comparing a ground source heat pump to a heat pump loop with
chiller and boiler. Trouble is, when I switch systems, the energy
used by the heat pump to heat the space goes down only slightly as
compared to the energy input by the boiler. My loop temperatures
change between the systems (from heating temp of 40 F to 70 F), and COP
rises accordingly. Right now the energy use of the two systems is
off by about 85%!! </DIV>
<DIV> </DIV>
<DIV>Energy use for straight electric resistance heat is about the
same as the electric use for a heat pump system. This is for a
baseline model with 18% evenly distributed windows, R-19 batt insulation,
R-38 ceilings, etc. </DIV>
<DIV> </DIV>
<DIV>I used the wizard to set up the equipment for all runs (I'm also
having trouble in detailed edit mode). The water loop and the heat
pump don't seem to be talking to one another. Can anyone help?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
