It should mention removing moisture. A standard air conditioner is moreso a giant dehumidifier then an air 'cooler'. Without seeing the actual design the first impression is some trays that hold water and freeze during nor.al operation. After electrical demand exceeds a set limit, or companies want to because they will most likely have the ability, they shut off the 'cooling' and just blow the room air across the frozen stuff giving the impression of cooling.

I'm hoping the frozen stuff is contained, but then you have the issue of expansion when it freezes. So who knows.

The "used in an evaporative cooling process" is the part where it sounds like it adds moisture to the air. I think it happens outside, though. It sounds like their whole thing is to run moist outside air over the dessicant, then run that dry air over water that is on a heat exchanger. This would cool the heat exchanger that would be tied to ductwork or whatever to cool the house. Evaporative coolers already exist (both as in-house "swamp coolers" and external chillers usually used on bigger buildings). They don't work if the humidity is already high, though, so this system would enable them to function better in high humidity areas, and it could take advantage of only doing the energy intensive step of drying out the dessicant when there is surplus energy.
