The Future Development Trend Of Curtain Walls

- Sep 11, 2017-

     It is necessary to analyze and study the complex heat transfer process and heat transfer mode in the design of curtain wall thermal engineering. The heat transfer process of the curtain wall is roughly 3 ways: the heat transfer between the outer surface of the curtain wall and the ambient air and the external environment: the convective heat transfer between the outer surface and the ambient air, the radiant heat transfer between the outer surface and the external environment, the external surface and the space of various long wavelength (such as electromagnetic wave, infrared ray, etc.) Radiation heat transfer Curtain Walls

     Heat transfer between inner surface of curtain wall and indoor air and indoor environment: convective heat transfer between inner surface and indoor air, radiant heat transfer between inner surface and indoor environment; Heat transfer of curtain wall and metal frame: through heat transfer of single-layer glass, heat transfer through metal frame, reducing radiant heat transfer through the coating layer of glass. The heat transfer coefficient of the curtain wall is determined by the shape of the building and the climatic conditions of the area, the heat transfer coefficient of the profile and the heat transfer coefficient of the glass.Curtain Walls

    Curtain wall is a new building material which has been developed in our country in the past 20 years, with new technology, materials and structure as a whole, and millions of square meters of curtain wall are put into use every year in our country, and continue to grow at 10% speed. Therefore, the building energy-saving design of curtain wall is very important. The structural form of the broken-hot curtain wall is the most effective way to save energy of curtain wall building.Curtain Walls

     From the surface, after five years of development, building insulation industry in terms of scale, talent, technology, or reduce energy consumption role, have made great progress, has achieved gratifying results, but from a professional perspective, we will find that there are many serious problems. Curtain Walls

     In recent years, many new buildings have done a lot of building thermal insulation, but mostly just to meet the requirements of the national mandatory policy, the overall performance of the insulation system is often not guaranteed, a large number of buildings in order to reduce costs, and not the real use of environmental protection and energy-saving, fire, waterproof and system Many building insulation has more or less hidden dangers. From the macroscopic point of view, we can find out the existing problems of building insulation.Curtain Walls
