Pineapple wrote:Great thread! My young camp Oontz Pouch uses 3 hexayurts for sleeping, and this year I'm doing A/C for them following your design. Planning to add a 15W solar panel to the system to slow the drain on the battery, though maybe I should just assume I will charge it when the generators are running at night.
I think I found a promising source of pumps, targeted at computer cooling. It isn't self-priming, but maybe that's a good thing--when it runs out of water (a distinct possibility with my camp's occasional responsibility lapses), it should lock up and stop running. From Amazon reviews, would take some poking/prodding with a paper clip to free it up again and re-prime it.

3.6L/min Mini DC Brushless Submersible Water. Ideal for CPU cooling
This is a compact size submersible water pump(none self-prime). It can be used inline or submersed for water pumping. It's built by a brushless motor providing smooth and quiet operation than a non-brushless water pump. Plus,it will not generate 'electric spark' like what a brush type does so it's more safe. It can be used to pump dilute oil as well (no gasoline*)

If you can calculate how much cubic feet of space you are cooling and divide that by the cfm of your fan and your answer is between 3 and 5, it will work.
If you can create a vent hole near the peak of the roof so the air can cycle out at the same rate that it enters from the fan, thats perfect!
