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
What’s your source for this? It routinely gets over 100 here and buildings aren’t 80 degrees inside.
They’re full of it, that’s it. Maybe in their house which lacks sufficient insulation. Heat pumps (i.e. air conditioning) are/is extremely efficient at moving heat around, there’s not really a practical limit on it, particularly if you go geothermal.
