Self-Cooling Windows Could Help Beat Summer Heat

【自冷窗户!帮你度过清凉一夏】仿照人体的循环系统,哈佛开发了一款可以自冷的窗户。在窗玻璃上装入一个超薄管道网(类似于人的血管),水可以在这个网中流动,从而加快热量传导。冷水从窗户旁边泵入管道中,把热量带走。这种仿生设计将在未来的建筑设计中扮演重要角色。

Self-Cooling Windows Could Help Beat Summer Heat

If you've racked up sky-high electricity bills this summer from using all that air conditioning, there may be an alternative solution that could stop heat from entering your home via one major source: windows.

Researchers at Harvard University's Wyss Institute for Biologically Inspired Engineering have developed a design for self-cooling windows that is modeled after the human body's circulatory system. Our body's blood vessels near the skin's surface dilate when we're feeling hot, which allows more blood to circulate, and cools us off, according to the institute. The idea is: Why not carry over that biological concept to the windows we have in our homes?

The institute's design incorporates a network of "ultrathin channels" near the window pane, through which water can flow, and encourage heat transfer. Cool water is pumped next to the hot window, which takes away the heat, researchers said.

After working with a Broad Institute mathematician to calculate the potential for this technology, Wyss Institute researchers found that running half a soda can's worth of water in this system could cool a full-size window pane by 14 degrees Fahrenheit.

The idea of using nature's lesson to create kind of a living skin on a building is a very important and promising direction for how buildings should and will be constructed in the future

The idea of using nature's lesson to create kind of a living skin on a building is a very important and promising direction for how buildings should and will be constructed in the future," Chuck Hoberman, a designer and Wyss Institute Visiting Scholar, said in a news release. 

Installing self-cooling windows such as these would allow residents to stay cool, while letting in sunlight. But the Wyss Institute also said this system could help cool rooftop solar panels, "allowing them to generate electricity more efficiently."
