Is a Portable Air Conditioner with Water Cooling Feasible for Garage Use?

You could also make a "dry-air" evaporative cooler. This was invented some time ago, and my father's company manufactured these until about 15 years ago. Basically, it's an evaporative cooler with a twist:

Instead of using a wet fiber/wet cardboard medium and blow air across that, wrap some thin wall PVC tubing with material. Run water over them and recycle it back to the top. Draw outside air across those tubes and exhaust that air back outside. Draw air THROUGH the tubes. This air will be cooled as it passes through the tubes into the space to be cooled.

It's not as efficient, but it is as dry as the outside air...

Good Luck!

I like this. Perhaps arranged in two chambers one blowing in with water sprayed over cloth covered tubes and the other blowing out with tubes used to condense the evaporated water back out of the air and pump back from there. You can only bring in air if you take it out anyway, so why not use the slightly cooler air to help condensing?
