1、幕墙专业英语强悍总结很系统Double Skin Curtain Wall Introduction： Double skin curtain wall (also called ventilation curtain wall, respiration type curtain wall, thermal channel curtain wall) is composed of outer curtain wall, inner curtain wall, sunshade, air inlet and air outlet. Compared with the traditional cu

2、rtain wall, its outstanding feature is that one ventilation air exchange layer is formed between inside and outside layers, which can improve the living comfortability and achieve the function of energy saving. Vocabulary： 1. ventilation curtain wall：通风式幕墙 2. respiration type curtain wall：呼吸式幕墙 3. t

5、comfortable .How does double skin curtain wall achieve these two advantages? Because of its good thermal break performance, the energy consumption is quite lowered; besides, as it can provide nice condition of ventilation, light and humidity, the indoor comfort is largely improved! How many kinds of

6、 double skin curtain wall? There are many different ways to classify double skin curtain wall. Basically speaking, it can be divided into two types according to the structure of the ventilation layer: “internal cycle double skin curtain wall” and “external cycle double skin curtain wall”. the struct

7、ure feature of these two types double skin curtain wall For “internal cycle double skin curtain wall”, its outer glass layer is generally formed by thermal break extrusion and insulated glass, its inner layer is generally formed by single-glass or opening window; while the “external cycle double ski

8、n curtain wall” is contrary.Comparing these two types of curtain walls, which one is better? Both of them have the advantages in the way of sun-shading, sound insulation, comfortable etc. But “external cycle double skin curtain wall” has better energy-saving performance.How does “external cycle doub

9、le skin curtain wall” work and save energy? Take it for example. In winter when we close the air inlet and air outlet, the temperature of air in the air exchange layer become higher under the sunshine, it effectively increase the temperature of the inner layer glass. While in summer, when we open th

10、e air inlet and air outlet, the fresh air will flow into air exchange layer and move from bottom to top, because the heat of air is carried away by the chimney effect, the temperature of inner layer glass surface is decreased. In that way, energy saving effect in Winter and Summer are achieved. Does

11、 the double skin curtain wall have the condensation trouble? From principle, the double skin curtain wall is beneficial to control the production of condensation through decreasing the absolute humidity of the air layer, eliminating the heat bridge and controlling the proper ventilation rate. What a

12、bout the width of the air exchange layer? In the projects in other countries, the width of the layer is approximately between 1,500 mm to 60 mm. The exact width of the air exchange layer must be taken into comprehensive consideration, including structural style, ventilation system, air flowing rate,

13、 heat preservation and sound insulation properties etc. We should give a precise calculation on it. Since double skin curtain wall has so many advantages, does it have any shortcomings? The cost of the double skin curtain wall is higher. And we still dont have enough evidence to prove whether it is

14、really energy saving or not. Are there any typical projects that used double skin curtain wall worldwide? The most typical projects are the headquarter building of Victoria Insurance Company of Germany and the RWE high-rise office building of Essen in Germany. The development of double skin curtain

15、wall? The double skin curtain wall came into use in 1990s in Europe and the technology has already gone maturity after years of generalizing. When this new technology is at the beginning in China, a number of countries in Europe and America have already combined the double skin curtain wall with the
