model a DX GSHP with refrigerant as the heat transfer fluid.  I would
appreciate any help.  Thanks.>

Matt,

While there are a few ways to "trick" the system into modeling DX GSHP
systems, your best bet is to probably write a new model that accounts
for
the refrigerant change of phase and the ground heat transfer.  We've
been
thinking about writing one of these for a while but haven't had a
project
where we NEEDED to write one....
