Lotta old Victorian homes and factories from that Era did the same thing (without water obviously just a big tower to catch the wind). More like an attic fan than an AC in those cases, still a pretty clever way to move air without electricity. Always impressed by how clever people were back in the old times
20 degrees is just a rule of thumb most ACs have a specific temperature change they’re designed to do. You can go past it, that’s just what the intented to do and it might not work as well or be able to do it. Fwiw I’d always heard 30 degrees farenheight for most window units. Had an hvac guy explain it to me years ago but fucked if I remember how it works

Ancient Iran had air conditioning (lemmy.world)
