With the swamp cooler, I used a 5 gal bucket as a reservoir and a 12v bilge pump to recirculate the water over the pad... This proto-type was used for testing different type pads for air flow volume and temp data... Using PWM speed controllers, air flow and and water feed are controllable from 0-100% ... On a dry day it'll deliver air at 24-28*f below ambient air.. When I say dry I mean 2-8% humidity, with an average of 6% at days end..
Max air flow on this model was 8-10 cubic ft a second.... Measured with a cheap anemometer at +/- 3.5%.. and depending on what pad was being tested... Even with the error factor, the temp. shift between conditioned air and ambient air should be close to accurate.. This morning 10:30 ambient air 92*f humidity 13%, fan on low, air off the cooler 66*f...
My 24/7 shadow couldn't go with me in the summer because of the heat, and the fact that sometimes she needs to stay in the truck for a short time... With this she sits in a cool breeze and keeps an eye on me and we both feel better...

That should be cool enough...
I took a class on metal casting and made a few pieces. I really enjoyed it. Nice piece...
