A few tips.  Cold air flows downward, this means the conventional
freezer-on-top refrigerator is extremely inefficient the more you use
(open) it.

So, use a floor model, that is contained on 5 sides like a bathtub
that has a lift-up top.

The more insulation (around all sides) the better, and if you use a
lift-up top, you'll hardly waste any energy.  If you have sunlight
shinging on the surface put a barrier.

If you can't use a lift-up top freezer, put empty, sealed boxes in
there to displace air, so you aren't having to re-cool the whole space
everytime you open it.

Keep plenty of ventilation space around the coil.  Maybe you can use
the heat for something so you don't lose energy.  Or put it on the
other side of the wall.

That's a few tips off the top of my head...
