Nature prompted cooling system windows

Researchers from the University of Toronto say they can improve the energy efficiency of buildings by filling the glass panes tiny water channels. The system operates on the principle of human blood vessels. Microchannel system is able to cool the room in the summer and reduce heat loss in the winter.

Researchers have developed a sheet of transparent flexible polymer “cooling layer” silicone penetrated by channels with a tiny cross-sectional height of 1-2 mm and a width of 100 microns, which circulates water at room temperature at a rate of 2 ml per minute. After heating, the prototype window size of 10 x 10 cm infrared camera recorded the decrease in glass temperature by 7-9 degrees Celsius. The water took heat from the heated glass and took him through the circulatory system. In winter, the process is reversed: room temperature water loses heat to the glass. All this allows to improve the energy efficiency of buildings.

For various lighting effects can be used different liquids. Scientists believe that this technology can also be used in photovoltaic systems. Full text of the work was published in the journal Solar Energy Materials & Solar Cells.

Scientists from the University of the State of Oregon, meanwhile promise affordable solar energy thanks to automotive antifreeze.
