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.
