With the continued rise in global temperatures, scientists are looking for inexpensive, environmentally friendly alternatives, especially in light of the rising demand for air conditioning units in buildings, one of which, according to the British newspaper “Daily Mail,” operates at a power of 10 k/watt.
Since previous studies have estimated that cooling accounts for about 15% of global energy consumption, researchers from the University of Kyung Hu in Seoul, South Korea, think they may have found a simple solution to this issue in the form of transparent window coatings that lower building temperatures without using any energy.
Normal glass windows allow for the passage of ultraviolet and infrared radiation, which results in a room temperature.
The researchers started working on a window covering that can block ultraviolet and below red sunlight to reduce the temperature of the rooms.
The researchers, led by Eungkio Li, explained that the transparent radiation coolant consists of thin layers of silicon dioxide, silicon nitride, aluminum oxide or titanium dioxide on a glass base, topped by a layer of polyxysan.
Researchers were able to enhance the type, arrangement, and installation of the layers through the use of automated learning techniques, achieving “a coating design has been reached, when manufactured, to perform traditionally designed recovery coating as well as the best commercial heat-reducing glasses in the markets.”
Researchers predict that when compared to standard windows, the use of cooling energy in hot, dry cities can be drastically decreased by 31%.
The researchers emphasised that transparent paint’s applications are not restricted to building windows; they may also be used to keep cars and trucks’ glass cool.
The study was conducted not long after American engineers invented “the most white paint so far,” which they claim will help treat global warming by lowering energy use and emissions from the use of air conditioners.
When compared to some types of paint that are now on the market and do not reflect more than 80 to 90% of the sun’s heat, the very white paint, which was developed at the University of Bordeaux in Indiana, may reflect up to 98.1% of the infrared sunlight.
