This is really going the other direction, but I have an old Servel
refrigerator, which uses ammonia/water as it's coolant, and what amounts to a propane pilot flame to "excite" the refrigerant. No moving parts, no
noise, no power, just relatively expensive propane.
It seems to me that a fridge like this could be located near a hot water source with a circulation pump (wood, solar, electric, gas, flubber powered, or whatever) or a loop added off a radiant heat system. Coiled copper tubing inserted into the fridges firebox would provide enough heat.
RV's use LP refrigerators still, so the technology is still available.
I've seen some plans on the internet for homemade ammonia refrigerant systems
