The invention is definitely great. My question here would be, as far as I understood the function - what is the % of humidity in the air after the unit has performed its job? Because I can image low humidity in the air might not be perfect for certain locations (of course too high as well), but a certain percentage should be maintained to keep us comfortable
"Once the air is dry, a second stage cools it using nothing but water evaporation"
As I understand it, the air is dried in the first stage to make the evaporative cooling stage more efficient. The second stage then adds humidity back to the air with the evaporation. I assume there is also a mechanism to control the humidity level. Happy to be corrected. :)
Right on the first half, Jannik! The nuance is that the evaporative cooling is indirect: part of the dried air evaporates water to cool a heat exchanger, and the supply air passes on the other side, getting colder without picking up moisture. The humid air is exhausted outside. And yes, humidity is set independently via the desiccant concentration.
Great question, Mariia! The unit dries the air to a target, not as much as possible. Humidity and temperature are controlled independently (the desiccant handles one, the evaporative stage the other), so indoor air can stay in the usual comfort range of roughly 40–60% RH. Conventional AC is the one that struggles here, since it can only remove moisture by overcooling.
