I've wondered about something like that as well.  If my fridge, freezer,
or Coke machine were modified to work like split air conditioners,
they would slightly cool the house in the summer instead of helping
to heat it up.  Living where I do now I can't implement it, but when
I move I'm hoping one or more of them can sit against the garage wall
and I can position the coils on the other side of the wall (in the garage)
by extending the plumbing a few inches where they attach to the fridge.

How about a ground sourced water cooling bus for systems?

Scroll down to "Water Cooling":
