I'm not sure that is an accurate description of the physics. Maybe the air next to the panel is cooler, accounting for the cooling sensation.
- yummypaint 6y agoThe cold air will contribute, but this is an accurate description. A person constantly radiates a blackbody spectrum determined by temperature, as does the surrounding room. We perceive ourselves as in equilibrium when we radiate as much as we receive. If a wall is cooler than the rest of the room, the person receives less infrared from that direction and perceives cold, even in the absence of convection.
- thefiregecko 6y agoThis confused me for a bit. The point of the system is to prevent energy from being reflected or radiated from a surface. Systems like this have been around for a while (https://www.energy.gov/energysaver/home-cooling-systems/radiant-cooling https://www.energy.gov/energysaver/home-cooling-systems/radi...), the news here is that this works with temperatures below the dew point because they have solved the condensation issues.
