The idea is that I take a humidifier and blow air across it, cooling the air via evaporation cooling. I think this is a relatively proven concept as it's how misting fans and swamp coolers work. This product seems to work in a similar function to what I'm planning, although I'd be using a cheap 2W USB humidifier instead of whatever fancy atomizer they use.
Ambient air comes in, gets combined with a stream of small water particles from the humidifier, and comes out as cooler more humid air. In this case, I guess the reject is the moisture in the out coming air? Heat isn't destroyed, but it's absorbed by the water for the phase change. Input dry hot air, output cooler humid air.
Since it's more effective when ambient air is dryer, I was looking for a way to optionally dry the air before combining it with the mist. I figured I could fan air over a dessicant before combining it with the water stream. Now, this might be where I'm misunderstanding thermodynamics - as another poster said, to absorb water is a exothermic reaction. With that in mind though, I'm OK with a one time item. Do you know if there is a such thing as a one time dehumidiying item, like ammonium nitrate, but for humidity instead of temp?
