In the central valley of California; places like Fresno, Modesto,
Merced, etc. , and places like Tucson and Phoenix in AZ. Those are all
places it is hot and dry, and prime places for what we call swamp
coolers; devices that depend on evaporation to cool a set of coils. Much
less expensive than AC, and if the humidity is low, they work very well.

Living in the high desert, I have wondered why builders haven't
offered options for integrating Evap coolers into the designs of the
houses. The biggest issue is the design of the sheets that the
water sheds through and the chemicals that are deposited. That
doesn't seem like it would be that hard to engineer. Something that
purifies the water first and has a changeable element like the water
purifiers for drinking water. Once a month change a $10 cartridge
and reduce your electrical bill by somewhere around 50-70% and
increase the humidity to a more livable level. I guess change is
hard. I ran one of the box coolers into a window for a few years but
the water issues were a pita. If the boxes had built in water
purifiers that would have been a non-issue. The systems really
needed to be taken up a notch to make them really a good solution.

OAT temps high 90s
Here is IAT of my shop in the welding and work spaces. (Have AC in
the office areas).
I have them (3 huge ones) on timers. They kick on about 7:30 each
week day morning.
You can see the humidity take a vertical jump when they come on.
IAT tracks OAT but the coolers make the slope of the line much less.
