Thermal solar sorption cooling systems, a review of principle, technology, and applications

open access: yesAlexandria Engineering Journal, 2022
Conventional energy consumption in refrigeration is one of the important reasons in global warming. Solar cooling systems are becoming more compact, having lower costs, and are potential alternative technologies, especially in hot and sunny climates. The

German/Egyptian demonstration project on solar cooling in a hot arid climate

open access: yes, 2022
S.991-996In Egypt, like in other hot arid countries the use of conventional electrically driven chillers for air conditioning (AC) is increasing dramatically, thus leading to high costs, power grid overload and blackouts.

Bridging Horizontal to Vertical Radiative Cooling. [PDF]

open access: yesAdv Sci (Weinh)
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...
