20 yrs in Phx. Blazing heat! Casa Grande not as bad, but still hot. Thanks for the great thread
It can be if you're using AC. Electric bills get crazy in the summer. Those swamp coolers only use a tiny bit of energy, however. The trade off is less fine control and a bit higher temperature range (80s rather than 60s-70s).Great threadExpensive grow in that AZ heat!
Found some great patents on swamp coolers that blow away what's on the market now. That's probably why they are not on the market!It can be if you're using AC. Electric bills get crazy in the summer.

The absolute max you can do with single stage evaporative cooling is a 40°f temperature drop from ambient.Found some great patents on swamp coolers that blow away what's on the market now. That's probably why they are not on the market!
In the first link, the inventor claims that the water gets down to 33F. That's cold enough for a nice indirect cooler.The absolute max you can do with single stage evaporative cooling is a 40°f temperature drop from ambient.
As humidity rises, this max temp drop decreases. On a 70% humidity day, you'll get maybe a 10°-15° drop...
With some 'Rube Goldberging', you might be able to dehumidify the cooled air and run it through additional evaporative stages, but as temperatures drop there's a diminishing return on cooling ability. You're looking at just a tiny bit more cooling power with a HUGE hit to CFM.
From what ambiant temp? 73°? ;-)In the first link, the inventor claims that the water gets down to 33F. That's cold enough for a nice indirect cooler.
