What you need to be looking for is an Ammonia based AC (rather than a
Propane fired one), which happens to use propane for the heat source.
Many decades ago (oops!) the house I lived in had an Ammonia based AC
system. It died (unusual) and was replaced with a heat pump.

Most modern ammonia based AC systems should be pretty fuel efficient.

The current thread dealing with battery power for the refrigerator
brought the above subject to mind..

The propane/115v refrigerator/freezer I had in my motor home some years
back was outstanding. When running on propane, it never let me down. Nor
did it on 115V electricity, either. It was not made to use battery power
in any way. And that thing would freeze a halibut solid as a block of
tombstone granite..

So my question is, if there are propane fired refrigeration units that
work well, can there not be a propane fired AC unit somewhere,
CERVEL(Cervil?), or some other brand. If not, could one be cobbled
together with parts from a propane fired fridge. After all, they aren't
much more than a coil, a fan, and a heating unit. It seems to me  if the
shape was right, it would work great as a cooler for the camper on the
weekend outing.

Ideas, comments, slams??
