Could I get a hundred feet of 3" corrugated drain pipe for the air and run it through a 6" corrugated drain pipe for running cooled evaporated water which would be pumped out of one end and gravity fed through the other end. As for the air "tube", I would run one end into the home at one location and the other end at the opposite end of the home with a fan pulling the cooled air through the "tube". Being corrugated, they have twice the surface area as a smooth hose, and I would snake them for added turbulence. Let's say the water is cooled to 65 degrees, what could I expect on a 100 degree day by recirculating the air through the home with a 2000 cfm fan and 1500 square feet? What if I buried the pipe 3-4 feet underground where the temp is 50-55 degrees? A 3" tube at 100 feet holds 18.75 cubic feet of air. I just don't know how to calculate this in order to see if it would be worth doing.
