Forget air conditioning.. Scientists develop transparent window coating to cool buildings without using energy

As global temperatures continue to rise around the world, the demand for air conditioning in buildings, which is not cheap, and consumes a lot of energy, is increasing, and according to the British “Daily Mail” website, scientists from Kyung Hee University in Seoul believe they may have a solution to this. The problem, in the form of paint transparent window.

According to the researchers, the coating lowers the temperature inside buildings, without spending a single energy, and previous studies have estimated that cooling accounts for about 15% of global energy consumption.

“In ordinary glass windows, UV and infrared rays from the sun can pass through, causing the room to heat up,” the report says. To prevent this, the team set out to develop a window coating that could block the sun’s UV and infrared rays.

The scientists were also aiming to make a coating that could radiate heat from a window surface at a wavelength that passes through the atmosphere into outer space. visible, which means that it does not interfere with vision.

The team’s transparent radiator cooler 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..

Using machine learning, the researchers were able to improve the type, order, and composition of the layers, explaining: “This produced a coating design that, when manufactured, outperformed the coating performance. TRCs Traditionally designed as well as one of the best commercial heat reducing glasses on the market.

The researchers expect that in hot and dry cities, the Telecommunications Regulatory Authority can reduce cooling energy consumption by a whopping 31 percent, compared to traditional windows, and window coating is not limited to buildings only..

According to the team, it could also be applied to car and truck windows to keep vehicles cool, and the study comes shortly after engineers in the US created “the whitest paint yet” – which they say will help tackle global warming.
