Title: RADIATIVE COOLING DEVICE AND RADIATIVE COOLING METHOD
Abstract:
Provided are a radiative cooling device and a radiative cooling method, wherein absorption of ultraviolet light is suppressed. This radiative cooling device 100 is provided with an ultraviolet reflection layer 10 that reflects ultraviolet light UV, a light reflection layer 20 that reflects visible light and infrared light, and an infrared radiation layer 30 that radiates infrared light IR. This radiative cooling device 100 radiates infrared light IR from a radiation surface 40, and is obtained by sequentially laminating the ultraviolet reflection layer 10, the infrared radiation layer 30 and the light reflection layer 20 in this order when viewed from the radiation surface 40 side.
