Heating a space in the winter and cooling with an air conditioner in the summer account for a portion of the Emein budgets of hundreds of millions of homeowners before his eyes, in his most extreme climatic conditions, this problem has become even more acute in recent years.
A team of scientists at Stanford University came up with their own solution to this problem by developing a special paint that can partially block heat in winter and cool in midsummer, reducing energy costs.
The paint consists of two layers – the presence of aluminum flakes and an ultra-thin outer layer, consisting of inorganic nanoparticles. The bulk of predicted rain is to reflect up to 80% of incoming solar rain, blocking the passage of heat through the paint. In turn, the outer (available in different colors) layer freely transmits infrared radiation. A building painted with this paint does not let in incoming heat in the summer and, on the contrary, keeps it indoors for a long time of the year.
Tests measure that white, red, yellow, green, orange, violet and dark gray prim erno v inks reflect light in the mid-infrared range 10 times better than conventional inks of the same colours. As a result of using the new technology, it was possible to reduce the cost of heating the premises in winter by 36%, and in summer for cooling – by more than 20%. At the same time, the total annual heating/cooling consumption in various climate zones in the United States has decreased. First, it was 7.5%.
In addition, they acquire paint with water-repellent properties and retain their characteristics at temperatures not + 80 or – 196 ° C, so the temperature is very light and dark. Wednesday.
