Researchers have designed a transparent window coating that can reduce the temperature inside buildings without spending a single watt of energy. This refrigerator could mean annual energy savings of up to MJ/m in hot climates.
As climate change intensifies summer heat, demand for technologies to cool buildings grows.
Now, researchers have used advanced Phone Number List computer technology and artificial intelligence to design a transparent window coating that could reduce the temperature inside buildings , without expending a single watt of energy.
Studies have estimated that refrigeration accounts for around % of global energy consumption. That demand could be reduced with window coverings that blocked the sun's ultraviolet and infrared light , the parts of the solar spectrum that typically pass through glass to heat a closed room.
Energy consumption could be reduced further if the coating radiated heat from the window surface at a wavelength that passed through the atmosphere into outer space. However, it is difficult to design materials that meet these criteria simultaneously and that can also transmit visible light, that is, that do not interfere with vision. Eungkyu Lee, Tengfei Luo and their colleagues set out to design a " transparent radiative refrigerator " (TRC) that could do just that.
The team built computer models of CRT that consisted of alternating thin layers of common materials such as silicon dioxide, silicon nitride, aluminum oxide or titanium dioxide on a glass base, topped with a polydimethylsiloxane film . .
They optimized the type, order, and combination of layers using an iterative approach guided by machine learning and quantum computing, which stores data using subatomic particles.
This computer method performs optimization faster and better than conventional computers because it can effectively test all possible combinations in a fraction of a second. This resulted in a coating design that, once manufactured, outperformed conventionally designed CRTs, as well as being one of the best commercial heat-reducing glasses on the market.
Researchers say that in hot, dry cities, optimized CRT could reduce cooling energy consumption by % compared to conventional windows .
