I am dubious of that interior radiant cooling design... I suspect the panels could easily end up below the dew point, especially in a room with lots of people in, and end up dripping water all over your kids birthday party.

It's used in commercial buildings, combined with a dew point monitoring system and some actual A/C to cool and dehumidify supply air.

The downside is that if the dew point (and thus wet bulb temperature) gets too high, the panels shut down, so when you need them most they don't work and the building becomes a sauna.

These don't work at all IN a room. They need to have a direct live of sight to the sky, or else you're just radiating the IR back into the room and you achieve no net cooling.

Watch the video. They are used in a room to absorb IR radiation given off by people in the room.
