High Tech Attack! University Of Texas Has Developed A New Type Of Hot And Cold Curtain.

Recently, researchers at University of Texas-Austin have developed a new engineering material that allows occupants to accurately control the energy and light through windows, allowing windows to transmit light without transmitting heat, or allowing windows to transmit heat while blocking light. Therefore, the cost of cooling or heating inside buildings can be greatly reduced.

This material is called dual frequency electrochromism. Material Science It has significant optical characteristics, which can selectively control visible and heat generated near infrared light. Recently, the research team from Texas, USA has made two major breakthroughs in electrochromic materials, one is the highly selective refrigeration mode, the other is the highly selective heating mode, which was considered impossible a few years ago.

When it is in refrigeration mode, it can block 90% of the near-infrared light and allow 80% of visible light to pass through. This can significantly reduce the lighting without affecting the interior of the building. Summer Energy consumption of refrigeration. On the other hand, under the heating mode, the coating containing titanium dioxide nanocrystals can be used to shield visible light and the near-infrared light can pass through. This design is on a sunny day. winter It will be very useful, because in this mode, the occupants can make the near infrared light as much as possible to transmit heat through windows, while reducing the glare of sunlight. Compared with the past, similar materials need to switch for a long time. This new technology only needs a few minutes to complete the cold and hot mode switching quickly, saving a lot of time, and is expected to be used in real life in the future.
