And there is ammonia-absorption-cycle refrigeration that is over 100 years old, and does not use a compressor at all. Jade Mountain sells an ammonia-absorption-cycle refrigerator that runs on a kerosene pilot light.

Servel Cycle AC was used in Texas when I was a kid. I think they're still around. They ran on natural gas heat.

My father ( who had an HVAC shop along with his main business, hazardous location wiring ) mentioned this type of cooler to me years & years ago... like about 45 years ago. They were popular at campsites and on small boats with no or tiny electrical systems.

They usually run off of "waste" heat. So you get "free" cooling. The draw back is that they are big and bulky and course there is that ammonia thing. Not real health stuff. But they do work well.

My family had an ammonia-absorption-cycle refrigerator (an Eletrolux, I believe) in the 1930's into the 1950's. It ran on natural gas. I remember that every time we had an electrical power failure the neighbors brought their butter and other valuables to us for preservation.

Used to occasionally run into those way out in the outback, back of the beyond, off the beaten path, when I was a kid. Had no idea they were still made!
