Cold island effect device

Abstract

The cold island effect belongs to a phenomenon of climate change. At present, human research on the cold island effect is only limited to the field of science, and does not involve the technical field of invention. The present invention realizes the first application of the cold island effect principle in the technical field. The cold island effect device of the present invention comprises a plurality of reflecting devices. The reflecting devices are installed above the ground, the water surface or the building, and the reflecting planes thereof are parallel to the horizontal plane or are inclined. Most of sunshine can be reflected back to the space, so that a relatively cryogenic cold island is formed on the surface region where the reflecting devices are located and the cold island effect is formed through the interaction of ambient atmosphere, thereby achieving the purposes of heatstroke prevention and temperature reduction and drought resistance and moisture preservation.
