Amazing! This glass curtain wall can change color to "cool down"

the first intelligent glass energy-saving curtain wall in China has been installed. Under high temperature, the glass curtain wall begins to fog, and the scenery outside the window is hazy. At this time, a large number of ultraviolet and infrared rays will be blocked outside

have you ever seen smart glass that can automatically adjust transparency according to temperature changes? Recently, the first intelligent glass energy-saving curtain wall in China was built in the planned exhibition hall of airport new town in Yubei district. Unlike ordinary glass curtain walls, intelligent glass energy-saving curtain walls can automatically adjust the transparency of the glass according to the temperature changes. The following is a preview of the forum topics, effectively blocking ultraviolet and infrared rays, and saving about 10% of energy consumption

it is understood that this is the first case of formal application of the product after the intelligent membrane industry project settled in Chongqing. In the future, more intelligent membrane products will come into our life

the magic transparent glass can change color with the temperature

on the morning of the 23rd, we came to the planning exhibition hall of the airport new town in Yubei District, which is under construction. The external facade of the exhibition hall consists of four glass curtain walls. Among them, the glass curtain wall on the west side uses intelligent glass energy-saving curtain wall, about 400 square meters

at 9:00 a.m., from the appearance, there is no difference between the four glass curtain walls, which are all transparent glass

around 10:30 a.m., the intelligent glass energy-saving curtain wall quietly changed. The transparent glass is gradually atomized. Looking out from the exhibition hall, it looks like a layer of mist. The other three glass curtain walls have no change

as the temperature rises, the atomization phenomenon of intelligent glass energy-saving curtain wall becomes more and more obvious. The landscape outside the exhibition hall looks like a layer of thick "fog", which is dreamy and poetic

around 1:00 noon, the intelligent glass energy-saving curtain wall becomes an opaque white glass curtain wall. Both inside and outside the museum, it forms a sharp contrast with the other three transparent glass curtain walls

around 5:00 p.m., the temperature drops, and the intelligent glass energy-saving curtain wall begins to change again, gradually recovering from non transparency to transparency. At 6:30 p.m., the sun sets, and the intelligent glass energy-saving curtain wall turns back to a transparent glass curtain wall

reveal why the smart glass energy-saving curtain wall has changed so miraculously by blocking ultraviolet and infrared rays to "cool" the room.

? Found the curtain wall manufacturer - Chongqing Hewei Technology Co., Ltd. to understand the reason

Denghua, chairman of Hewei technology company, explained that the glass used in the intelligent glass energy-saving curtain wall is a kind of "thermal dimming insulating glass for building". This kind of glass will change color according to the change of temperature because there is a layer of intelligent nano gel film in the middle of the glass

it is understood that this intelligent nano gel film was developed by wenweijia, Professor of Hong Kong University of science and technology, and obtained a national patent. In the normal state, the smart film is transparent; When the temperature rises, it becomes opaque gradually; When the temperature decreases, it becomes transparent again

the direct effect of such changes is to effectively block ultraviolet and infrared rays. Tests show that when the smart film is in an opaque state, it can block more than 98% of ultraviolet and more than 97% of infrared rays, and the blocking effect is better than many heat-insulating curtains

the thermal insulation film temperature tester shows that under infrared radiation, the temperature rise of ordinary insulating glass exceeds 10 in one minute; Under the same infrared radiation, the intelligent film in the opaque state heats up less than 2 in a minute, which can effectively block ultraviolet and infrared rays, reduce the harm of ultraviolet rays to human body, reduce the impact of infrared rays on indoor ambient temperature, and achieve the effect of "cooling"

it is found that after the smart film becomes opaque, the visible light transmittance does not change much, which will not have a great impact on indoor lighting

in the future, "made in Chongqing" smart films will go abroad

it is reported that smart films are already on sale in the market. "At present, the intelligent membrane sold in the market mainly depends on the change of current to change the membrane state. Most of them need manual adjustment and consume electric energy." Denghua said that the intelligent nano gel film is the first passive intelligent dimming film in China, and it is also a real intelligent film

the intelligent nano gel film can automatically change the state of the film and the degree of transparency according to the outdoor temperature without consuming any energy, so as to truly realize intelligent control and energy saving. Experiments show that what is intelligence? The nano gel film can save about 10% of energy consumption

at the same time, the color change temperature of intelligent nano gel film can be customized according to actual needs, and the color change temperature range is -20 to 70. The color change temperature of intelligent glass curtain wall of airport new town planning exhibition hall is customized at 35

in addition to effective energy saving, intelligent nano gel film can also promote the growth of crops. Yunnan Academy of Agricultural Sciences used intelligent nano gel film to make a greenhouse and conducted a planting experiment for about 18 months. The results showed that the crops grew better and the yield was higher

at present, the "made in Chongqing" smart membrane has received orders for less new construction projects of plastic wood composite materials that are not used for outdoor building materials in China. A new landmark building in Penang, Malaysia, will also use the "made in Chongqing" smart membrane

next, intelligent nano gel film will accelerate research and development and achieve mass production. By using high-tech means such as "hanging film" technology, intelligent nano gel films can appear in more forms. For example, the intelligent film that can be directly attached to the fixture of the ordinary glass pulling machine as an important part of the instrument has been developed to enrich the color of the intelligent film, which can not only meet the energy-saving transformation of buildings, but also meet the individual needs of consumers
