Atmosféra má infračervené "okno" ktoré to umožňuje. https://en.wikipedia.org/wiki/Radiative_cooling#Applications In 2014, researchers developed the first daytime radiative cooler using a multi-layer thermal photonic structure that selectively emits long wavelength infrared radiation into space, and can achieve 5 °C sub-ambient cooling under direct sunlight. |
