I'm assuming that they work on a similar principle to the kerosene
refrigerators I recall from a few decades back; a neighbor in a rural
area of UK with no electric supply had one. Some of those used ammonia
as the refrigerant, but maybe the propane ones now use Freon.

IIRC, the heat of the flame raises the pressure of the refrigerant just
as the compressor does in an electric refrigerator.

IIRC, the flame boils the ammonia, it condenses, and as it does, cools,
hence, cooling.

Oh for heaven's sake! When things condense they give off heat; so why
would it cool by condensing?

I don't know. If you are so smart, why don't you post the answer instead
of just coming up with contentious posts? Explain it to us stupid
unwashed rabble.

I shouldn't have to explain it. Some reason you can't read the perfectly
clear link I provided you (for those of you too stupid to know how to use
google.)

An ammonia refrigerator has a flame and ammonia. I don't really
understand how it works, only that it does. A flame would seem to boil a
liquid, and a condensing coil would seem to condense that vapor.

Okay, you seem to understand it; when you add heat to ammonia, it changes
from a liquid to a gas. When you condense it, it gives off that very same
heat. How could giving off heat cool a refrigerator? Wouldn't it heat the
refrigerator? (Hint; is the compressor of your A/C the inside or outside
unit.)

If you are a troll, you are a very good one. If you are not a troll, you
have to try thinking.
