Testing out my homemade DIY two-stage evaporative cooler in 99° F temps in the desert at Bombay Beach Salton Sea. runs on 12 volt solar power and water.
Really cool. I wonder if the system might be more efficient if you ran inside air through the heat exchanger so the second stage could cool and re-cool the interior air without having to cool the 99-degree outside air. I plan to build one of these for my home, and that's my plan. Let the first stage take place outdoors, cooling the reservoir water, and then keep the second stage completely inside since there's no concern about a buildup of humidity.
Nice Work. I am working on M-Cycle kind of cooling and did work on changing my swamp cooler to AC by installing refrigerator size compressor ( 1.5amps)and installing heat exchanger to let the chilled water flow through the chiller and output temprature was -11F, which is too cold :)
Awesome! I was thinking of making a swamp cooler for my school bus but I love the humidity the house one gives off it goes from the normal 15% to 30-35%
You keep door/window open or some ventilation to outside to let cool air in and reduce humidity w regular evap cooling. Couldn't hear everything but I'm thinking this wouldnt bring in much humidity. It would've helped to make video after it's on an hour+ to see inside temp. I'm just wondering if there's enough output but love the idea.

Awesome video, please make more Salton sea area videos.

Genius I was just thinking this would be great for home use but I guess you've already gone further with a mobile version thanks for doing the video!
I love video content like this
You should do a more thorough breakdown of parts, and how it functions. Looks pretty sweet 2 stage cooler.
Thanks. I plan to do so very soon. Stay tuned.
it looks like you are running water on a pad in the 2nd tank, so wet air into the living space? a drawing of the config would be very helpful, thanks

Does it still work if the heat exchanger uses water from the reservoir of the direct evaporative cooler?
This is called indirect air cooler ? Evap cooler + coil copper cooler (?)
Maybe No added humidity
👍👍👍
