With global temperatures continuing to rise around the world, scientists are seeking to find environmentally friendly and low-cost alternatives, especially after the increasing demand for air conditioners in buildings, which are estimated to operate at a power of 10 kilowatts / watt, according to the “Daily Mail” published ” British.
Possible solution to the cooling problem
Scientists from Kyung Hee University in Seoul, South Korea think they may have solved this problem simply in the form of a clear window coating that lowers the temperature inside buildings, without spending a single energy, especially since previous studies have estimated that cooling accounts for about 15% of energy consumption. global energy.
Ultraviolet and infrared
In ordinary glass windows, the sun’s ultraviolet and infrared rays can pass through, heating up the room temperature. To prevent rooms from overheating, the researchers set out to develop a window coating that could block the sun’s ultraviolet and infrared rays.
alternating thin layers
The researchers, led by Eungkyu Lee, explained that the transparent radioactive coolant consists of alternating thin layers of silicon dioxide, silicon nitride, aluminum oxide or titanium dioxide on a glass base, topped with a layer of polydimethylsiloxane.
machine learning techniques
Using machine learning techniques, the researchers were able to improve the type, order and texture of the layers, explaining that “a coating design that, when manufactured, outperforms conventionally designed cured coatings as well as the best commercial heat-reducing glasses on the market.”
The researchers predict that in hot and dry cities, cooling energy consumption can be reduced by a whopping 31 percent, compared to conventional windows.
Buildings and cars
The researchers pointed out that the uses of transparent paint are not limited to building windows only, but can be applied to the windows of cars and trucks to keep vehicles cool as well.
The whiter paint
The study comes shortly after engineers in the US created the “whitest paint yet”, which they say will help tackle global warming by reducing energy consumption and reducing emissions from air conditioning.
The ultra-white paint, developed at Purdue University in Indiana, reflects up to 98.1% of the sun’s infrared rays, compared to some paints currently on the market and reflects only 80 to 90% of the sun’s heat.
