Ancient Iran had air conditioning - Lemmy.world

Cool, but a quick search shows that these towers can cool a place by around 10C. So, in the scorching 50C desert, the interior would be above 35C, which is still fucking hot.
A modern home ACs can only cool about 20f below the outside temperature. 50c to 35c is 27 degrees so that’s pretty damn good for a fancy swamp cooler
That’s just not true, a modern home can be at 70f or below when its 110f outside. Air comes out at 50-55 even at those outside temps.
