Liquid smart glass protects from heat during the day and keeps warm at night (2 photos)

Energy-saving technologies permeate allspheres of human activity. The original liquid window panel developed at the Nanyang University of Technology in Singapore will help keep the heat accumulated during the day in the room at night and protect it from the scorching sun during the day.

Using the invention in everyday life will reduceheating and air conditioning costs. The installation of "smart" window panels, according to the inventors, will reduce the energy consumption for heating, ventilation and air conditioning of a building by 45% compared to traditional windows. At the same time, the efficiency of saving liquid glass panels is 30% higher than the indicators of energy-efficient glass with a reduced emissivity offered by the industry.

The operating principle of smart window glass is based oncharacteristics of the gel, which fills the inner space of the glass unit. The mixture of microhydrogel, water and stabilizer has been tested in various climatic conditions. The technology works thanks to the ability of the working mixture to change transparency under the influence of temperature.

Afternoon under the influence of sunlight, gel,located in the glass panel becomes opaque and "takes" the energy of the Sun. By evening, the panel cools down, the heat goes to heating the room, and the window becomes transparent again.

Testing technology using data onweather in four cities (Shanghai, Las Vegas, Riyadh and Singapore) showed that the smart liquid window has the best energy efficiency in all four cities. And in addition to being energy efficient, smart glass has been found to be 15% better at protecting a room from noise than standard double glazing.

The UK is also exploring the possibility ofthe use of liquid panels, however, the British proposed pumping out the water heated during the day and using it for heating. This method is more laborious, requires additional equipment and energy consumption.
