Vacuum double-layer curtain wall opens up a new way for building energy conservation

as the first in China, "because there is no standard requirement for the new energy-saving double-layer curtain wall with excellent cost performance, vacuum glass double-layer curtain wall improves the performance of double-layer curtain wall, and the cost is similar to the traditional hollow glass double-layer curtain wall. Its use will provide a new way for building energy conservation. Compared with ordinary glass and insulating glass, vacuum glass has many advantages, but due to technical problems, there are only production lines in Japan and China. It is understood that South Korea, France, Denmark and other countries are also developing vacuum glass, but it has not yet reached the level of industrial production. China is the second country in the world with the industrialization technology of vacuum glass production

the application of double-layer curtain wall should be adapted to local conditions

long Wenzhi, a curtain wall expert of China Building Metal Structure Association, said that the double-layer curtain wall was introduced into China in 1998. At present, there are more than 50 building applications. Although there are successful cases, since November 2014, the light textile room has cooperated with the personnel of the equipment manufacturer to install and debug seven sets of equipment such as "ring stiffness", but there are few satisfactory projects. The reason lies in the blind design and simple copying of the technology of foreign cold zone countries, the low construction quality, and the failure to understand that the double-layer curtain wall is a "climate adaptive" peripheral protection structure. In addition, there is not enough research and independent innovation combined with China's climate characteristics

vacuum glass double-layer curtain wall opens up a new way for building energy conservation.

long Wenzhi said that the development of double-layer curtain wall cannot copy the structure of foreign countries or a foreign company, but to learn and eliminate the functions of digital display spring testing machine and characterize foreign technology, combined with China's geography, climate and environment, develop energy-saving, comfortable, economic The double-layer curtain wall with excellent cost performance is also an urgent task for the healthy development of double-layer curtain wall

the double-layer curtain wall not only plays the role of dividing space, but also is the medium of energy exchange inside and outside the building. Long Wenzhi said that the double-layer curtain wall structure of the building facade can establish a buffer zone between the building and the surrounding ecological environment, which can not only prevent the impact of changes in extreme climatic conditions to a certain extent, but also promote the effect of various microclimate adjustment methods required by users, provide a good microclimate environment for the building system, and try to meet the various biological comfort requirements of users. The combination of double-layer curtain wall design and energy-saving concept is finally reflected in the thermal insulation, sunshade, heat insulation, comfort design and solar energy utilization of the structure. While paying attention to the dynamic balance of energy, it pursues the comfort of the internal space. The ecological energy conservation, solar energy utilization, human comfort and other functions are organically combined to give full play to the ecological function of the double-layer curtain wall design

compared with the single-layer curtain wall, in addition to the performance of energy saving, some performance of the single-layer curtain wall can not be achieved or is difficult to achieve, such as natural ventilation, high-performance sound insulation, indoor comfort, etc. of high-rise buildings. Double curtain wall is the foundation of intelligent curtain wall. The selection of double-layer curtain walls for buildings depends on time, place, demand, economy and other factors. As a new type of external enclosure structure, double-layer curtain wall is still mature and developing

vacuum glass double-layer curtain wall deserves to be vigorously promoted

it is understood that double-layer structure curtain wall is widely used in Europe, and the research is relatively detailed. Countries and companies have their own characteristics, such as Germany's double-layer structure curtain wall of external circulation system is widely used, Italy and Britain's double-layer structure curtain wall of external circulation system is widely used, and France's double-layer structure curtain wall is widely used in the reconstruction of old buildings. Even in Germany, companies such as scheuger, Gartner and vicona have their own advantages. Long Wenzhi said that China's geography, environment, conditions and national conditions are very different from those abroad. Most of China's regions are cold in winter and hot in summer. Compared with regions with the same latitude in the world, the average temperature in January is about 14 ℃ lower in the regions with wheel and spoke sensors in Northeast China, about 10 ℃ lower in the middle and lower reaches of the Yellow River, about 8 ℃ lower in the south of the Yangtze River and about 5 ℃ lower in the southeast coast. The average temperature in July in most regions of China is 1 higher than that in the same latitude regions of the world. 3℃~2。 5℃。
