Scientists are developing a "smart" window that does not pass the heat


14/10/2007

Apparently, air conditioners soon be a thing of the past. Thanks to the scientists from the University of London we stop sweltering and look cool on hot sunny days.

The researchers report that they were able to develop "intelligent" coating that, when applied to glass houses or cars will be able to reflect the sun’s heat.

While conventional tinting glass and transmits light and heat, developed on the basis of the derivative of vanadium dioxide coating allows light to pass through unhindered, while reflecting infrared rays, if the temperature is above 29 degrees Celsius. Waves cause infrared heating, therefore, blocking of such waves reduces heat from the sun.

The ability to cover the pass or reflect light depending on external conditions provides an additional level of comfort to the consumer: a cool day in the sun’s heat easily penetrates into the room, heating it. But should the temperature rise above 29 degrees Celsius, the coating will reflect heat rays by 50% more efficient, allowing you to store in a cool room, even on a very hot sunny day.

Such a development would be very useful in the hands of architects and designers. From now on, they will not have to choose between the tinted glass to reflect extra sunlight and air conditioning to cool the rooms. Natural light and heat will become the norm in modern living and working environments. Interesting science and technology news only on pages of our portal.
