Probably an absorption unit using ammonia.
My brother has bought a boat, it has a small ref. 6000btus and runs off propane or 12DC. it works but I want to know how and what kinda of refrigerant it uses. The data plat shows >46 as the gas. There are no fans or compressor it does work and I have some idea of how. but would like a short detailed description
Thanks
