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.

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. Just an observation by
this untrained person.

If things give off heat when they condense, why isn't rain hot? Just a
question from this stupid person who obviously doesn't understand and know
as much as you.
