A few years ago, I found an interesting cooling idea that does use duct work, but, is very simple in that, you just bury 4" PVC, about 6' deep, and about 100' to 150' long. I think it was called "Earth Tubes". We are thinking of implementing this idea. I was about to post about this when I came across your post. Are you familiar with "Earth Tubes"?
Janet Williams wrote:Thanks guys. We live in Mississippi, so its very hot and humid. Sounds like the Earth Tubes would not be a good option. And we're not off grid, but I'm going to explore the evaporative cooling, and let my Hubbie read about this other system.

I understand there are a few systems around but they have not found acceptance, probably because they use ammonia. I have been following the progress, and lack of it, of a company in Austria, SolarFrost, for several years. A local hvac store owner here said there was a company in San Diego that built similar systems.
