I live in Central Texas. I was wondering if this is the right place for evaporative cooling?

I was wondering is this the correct forum for evaporative cooling?

I'm wanting to make a Persian wind catcher I've  been interested in for a while but my family informed me it's too humid here for swamp coolers and that evaporative cooling wouldn't work.

Is there a way to passively dehumidify the air as it comes into the wind catcher so that way it cools down as it goes over the pool of water?

The best way to find out if the area is dry enough for swamp coolers is to look around, especially in older neighbourhoods, and see if houses have them. I know they're viable in West Texas, but once you get to the hill country I think it's too humid.

What about a design like the Persian system that takes incoming air underground to shed some of its heat? Or if you're up for more engineering and don't mind energy dependencies, using a water loop sinking in a geothermal well with a heat exchanger?

If I understand you question based on your diagram the wind forum might be appropriate.

conservation might make sense.

I don't know about your second questions as I have not tried to cool air by sending over a pool of water.

Years ago folks all over Texas used evaporation cooler because there was no air conditioning.

How would I get it further underground? Would pipes work and I've never designed one before it was just the diagram I found online on how they work.

You can use desiccants to dry the air 1st.  Such a system alternates airflow between the air you intend to cool, and then heated air which dries the desiccants back out.  There's  a lot more moving parts and engineering, but desiccants make it possible to cool in humid areas.

that said, its getting less humid in central texas lately.   maybe what you have plus a window unit for backup is good

Hello all,

35 years in the hvac industry here. Look into the “coolerado” @ https://www.seeleyinternational.com/us/commercial/brands/coolerado/

Thanks 😊  I'll check that out and I've read the replies now. Sorry I've been away from the forum for a little while and I've never been super active here.
