IIT Guwahati Researchers Develop Electricity Free Radiative Cooler …

Webb16 mars 2024 · In this work, we demonstrate that optimally designed wavelength conversion in the visible spectral region allows the realization of radiative coolers with any desired color in the entire absorptive color space, including black and other dark colors, while still achieving daytime sub-ambient cooling. Webb6 juli 2024 · The radiative cooler is an electricity-free system which absorbs heat from the surroundings, and incident solar radiation, and emits heat into outer space and reflects the solar radiation. The coating is applied on rooftops and the cooling system acts as an alternative to ACs ( Image Source : ABP Live (with special arrangement with IIT Guwahati) ) Webb14 okt. 2024 · The device can also switch between solar heating mode (high solar absorptivity and low thermal emissivity) and radiative cooling mode (low solar absorptivity and high thermal emissivity) by controlling the optimal electrodeposition morphology for surface plasmon resonance. knippfulop19401120 t-online.com
