Scientists have proposed to replace the air conditioning on mirrors

A team of US scientists has developed and introduced the concept of a new cooling system for urban buildings. According to the researchers, because of their project in the near future city buildings will be able to abandon the use of air conditioners. Achieve such a result was possible thanks to scientists rethink some of the technical aspects.

As you know, in the cities of the air in the hot season heats up much more than say in nature. The reason for that – the use of different “not natural” materials that are perfectly accumulate heat and radiate it slowly while warming the atmosphere. Special contribution to the heating of the air and makes the asphalt covering the roofs of buildings, which is designed to protect them from water and cold.

A roof covered with black material is heated to 60 degrees Celsius greater than the ambient air. The roof is covered with non-painted aluminum is heated to 40 degrees more, and the roof Uslan mirrors – becomes 5 degrees colder atmosphere.

So, scientists have proposed to cover the roofs of the buildings mirrors. It is not so expensive and more – even beneficial, because the sun heated the roof heats the entire building, the air in and around it, which makes it “inhabitants” to use air conditioners. And in the summer they take on the order of 15% of the total electricity.

The mirrors reflects up to 97% of the incident light, and its cooling capacity is up to 40 watts per square meter. Only in the three-story house it will save at least 100 megawatt-hours of electricity. It goes to the project need not necessarily mirror. Each of them should be covered with an additional layer of silver, silicon dioxide and hafnium oxide. The last two material and converted into a real mirror termoizluchatel. Despite a lot of “terrible” substances, scientists claim that from an economic point of view, this project is still saves.
