   Not to be pedantic but that sounds more like an evaporative cooler than an air conditioner.

      Nope, it’s an air-conditioner. It’s using the same principle as every aircon does. Passes warm, humid air over a cooling element to condensate the moisture in the air, and as a side effect, cooling it.

   So, how much power does it take to create the ice?

   yea not a air conditioner, this would have no effect at all in humid climates

   This is not an evaporative cooler. An evaporative cooler works by, well, evaporation, of water into the airstream. The water is not chilled or frozen before contact with the air. Hot dry air goes in and cool humid air comes out. The maximum cooling potential is the difference between the dry bulb and wet bulb temperatures of the air. That’s typically about 10 deg C – not the 21 deg C air temp difference described by the article.
   In this device, the heat sink, ice, is much cooler than the wet bulb temperature of the air stream. In fact, since ice at 0 deg C will be below the air’s dew point, water in the air will condense out of the airstream – warm moist air can go in and cool dry(er) air will come out. Condensation is the opposite of evaporation.
   Imagine leaving the ice brick in the milk jug and putting the lid back on (evaporation not possible even after the ice has melted) – will the air still be colder at the outlets? Yes it will.
   As long as the ice is separated from the air stream or if the ice (eventually ice/water slurry) is at a temperature below the air’s dew point (saturation temperature), evaporation is not physically possible. As Homer Simpson said – in this house, we obey the laws of thermodynamics.

   I’ve just setup a tent next to my open fridge. I got that idea, when i noticed that the fridge was cold.
