Dr Farraj Al-Ajmi pretty much did this for his PhD studies at
Loughborough University (UK). It's described in
Al-Ajmi, F., D.L.Loveday and V.I.Hanby 2006 ``The cooling potential of
earth-air heat exchangers for domestic buildings in a desert climate''
Building and Environment 41:235--244.
and
Hanby, V.I., F.Al-Ajmi and D.L.Loveday 2004 ``The optimal design for a
ground cooling tube in a hot, arid climate'' Building Services
Engineering Research and Technology 26(1):1--10.
Farraj wrote TYPES for the ground cooling tube and the subsoil
environment. I've lost touch with him but I think he has posted here in
the past. He might be able to help you with some code. I modeled the ac
unit sing a fixed temperature approach for each coil (evaporator and
condenser) then assumed a fixed fraction of Carnot to get the energy
consumption.
