Recently, scientists have recently developed a spray can into a wall radiator. University of Nottingham China Campus researchers invented this technology, they developed a spray can absorb heat during the day, when the temperature drops slowly release it.
This breakthrough technology will effectively reduce energy consumption, save a lot of money, expected to be 35 percent effective in reducing indoor heating costs, it will be on sale within the next two years. At present, this spray is called 'non-deformed material change in energy storage (PCM)', the heat source is distributed excess room heat.
When the indoor temperature reaches a certain level, the spray material will store extra calories, for example: suitable for room temperature of 22 degrees Celsius. It has a ubiquitous application, adapted to Brick walls, and walls inside the wallpaper . University of Nottingham in the UK Sustainable Energy Center lab, researchers have been condensed into a large spray material thin coin.
By Joe - Dake Wa (JoDarkwa) and colleagues, Professor Oliver - Su (OliverSu) cooperation to complete the study, they said, as this material can work as the spray, on surfaces to form a micro-thin layer. At a certain temperature above the spray of particles to melt, they are not the formation of water droplets, but in the form of a special cover. After these substances will become solid, the heat distribution in the room.
Scientists believe that this spray can be used for the construction of new building materials, and effectively save energy. At the same time, they stressed that this will significantly reduce carbon emissions. Dake Wa professor, said the construction industry will generate more trade than the rest of the world's carbon emissions, even more than air flight. In some developing countries, the construction industry is the highest energy consumption unit, and emit large amounts of pollutants. If this material can be widely used, it will significantly affect the world, help reduce carbon emissions.
But this is not out of the spray material and air-conditioning , this is because people still need air conditioning to control humidity and air circulation. They can only reduce emissions of excess house heat. The team believes the future of the material can be applied to solar cell panels and LED lighting .
Currently, they are studying what kind of paint can be used in conjunction with the spray material, and no environmental impact. At the same time, they will explore more green way, and thus effectively reduce the world's carbon emissions.
