Hot air rising up the tower creates a low pressure in the chamber, which sucks in air from the quannat.
It was Yazdi technology, from the pre-islamic period of Persia.

Persia? Isn't that the place the US Military is poised to bomb into the Stone Age because they refuse to use our fake currency?
I could see wanting to replicate this clever system, but Zoning wouldn't allow for the tower, the EPA would prohibit due to the proximity to water, the bank would still require AC for a mortgage....
US mil isn't bombing Iran because Hillary isn't president, and the last significant chickenhawk, Bolton, was fired.

No the holes in the tower are on the downwind side which creates a low pressure zone. The wind is pulling air out of the tower. If wind reverses so does the air flow direction. Cool air would come out of the ground hole instead of into the home. They must have had a way to close the vents on the tower or to close the ground holes if the wind changed.

Basically a swamp cooler.
Funny how things called “swamp coolers” don’t work in the swamp where it’s so humid the moisture can’t evaporate and therefore there’s no way to cool the fuck off God I’m ready for winter to start.
Tornado Alley = the midwestern US = where all the food comes from
However, tornadoes, in spite of the potential damage they can cause, are often surprisingly small, and enough early warning is provided that there's enough time to seek shelter. That doesn't mean that your farm or home won't have damage, but it beats living in NYC or Commiefornia.

So it releases cooler air into the atmosphere. Instead of keeping it in the building.
Makes perfect sense.

Persians aren't the same breed of human as arabs. They are smarter and generally less fundamentalist. Their biggest problems are that the world wants their oil and the Rothschilds want to control their currency. Their only defense against this is to run a strict theocracy to keep the population homogenous and unsubverted. They broke free from (((US))) control in the 70's and have been Israel's biggest adversary since.
They're mudkikes, that means they are no better than any other regular kike. Child raping subhuman trash.

Islam is a drop in the bucket. Humans have been “human” for 150,000 years.

Much more like 200,000 years. We are shells of our former capabilities

I figured this would only work for a few days until the tunnel walls warmed up. The evaporation pool would make a lot of sense.

Like termite mounds.
Edit:
Apparently people are idiots.

What makes the hot air go down the hole when hot air rises?

No.
Venturi is caused by reduction in size of port.
These towers use simple redirection and/or the Coanda Effect. Temperature gradients.

That makes sense. I see the water canal now.
[–] SpeshulSnowflaek ago
Correct. This device is a giant carburetor, except instead of fuel, it pulls cool air.
[–] StuffThatSandwich 0 points 12 points 12 points (+12|-0) ago
The opening is placed facing the same direction as the wind typically travels (apparently some wind towers can change which side is opened too), this sucks air out the top, which in turn sucks air through the hole in the ground.

Okay. I see the water canal now. That makes more sense.

I think this was made before the goat fuckers came to power. At one point long long ago (before the Arabs and turks). They were much closer to being European. But not quite

Suction, just like your sister's ass.
Air contracts underground, then heats up as it rises through the house. Both of these pull air through the system. Having the upper window downstream helps improve efficiency, but it could also use a simple flue design.
