[BLDG-SIM] Water-to-Water Heat Pump Chillers and GLHE's

In eQuest I am attempting to model a proposed system that utilizes a
'well-water-to-water heat pump' type chiller that will be attached to a
vertical well ground loop heat exchanger. The chillers are modular and
cycle on and off to meet demand, so they operate at a constant
efficiency. They will be providing HW and CHW to 2-pipe fan coil units.
The DOE2.2 documentation indicates this chiller type is Heat-Pump and
that this chiller type can only be attached to lake/well water loop. By
selecting the lake/well water loop, I am unable to define the vertical
well characteristics, i.e well depth, configuration, etc. Does anyone
know of a way to attach the Heat-Pump type chiller to a vertical well
system? If not, is there a method to better describe the capacity of
the lake/well loop? And finally, does anyone have experience modeling
this system type and can provide any insight?
Thanks,
Jeff
