Have you never heard of Evaporative Air or "Swap Coolers"......that's the main method of cooling air here in NM. The box sits on the roof and fills with about 5 inches of water at the base of the pan, it pumps water up and it trickles down through pads on all sides. It then pulls air in, through the wet pads, cooling the air and pumping it throughout the house. It works great down here (much cheaper than Refrigerated Air)

And my parents have a Refrigerated Air system installed at their house, and it replaces all the air in the house with fresh outside air every hour.

 

Ya, we call 'em swamp coolers because of the green slimy condition of the condenser. We run 'em at work ... 5 story jobbers. But we are only interested in cooling the water and then the water cools my chiller. I have been doing this stuff for a while and being east of Hotlanta consider outside air a bad thing ... refilter the inside stuff and be safe

 

regardless of A/C
That was a f**kin cool explosion, rain of fire, looked like the Apocalypse or something
