Awning Motors Factory Introduces The Architectural Details Of I


    Awning Motors Factory introduces the construction skills of installing electric sunshades:

    1. The effect of shading on solar radiation. The thermal insulation performance of the envelope structure is affected by many factors, of which the most influential index is the shading coefficient. Generally speaking, the shading coefficient is controlled by the characteristics of the material itself and the environment. The shading coefficient is the ratio of the solar radiant heat through the enclosure structure with shading measures and the enclosure structure without shading measures. The smaller the shading coefficient, the smaller the solar radiation heat through the outer protective structure, and the better the heat-proof effect. The shading coefficients of the main windows in Guangzhou area are: 17% westward, 45% southward, and 60% northward. It can be seen that the effect of sun shading on shielding the sun's radiant heat is quite large, and the shading measures for glass curtain wall buildings are even more effective.

    2. The effect of shading on indoor temperature. Shading has a significant effect on preventing indoor temperature from rising. Experimental observations in a west-facing room in Guangzhou show that with closed windows, with and without shading, the maximum difference in room temperature is 20 ℃, and the average difference is 1.4 ℃. Moreover, when there is sunshade, the room temperature wave amplitude is small, the time delay for the maximum room temperature appears, and the indoor temperature field is uniform. Therefore, shading can reduce the cooling load of air-conditioned rooms, so for air-conditioned buildings, shading is one of the main measures to save electricity.

    3. The effect of shading on daylighting. From the point of view of natural lighting, shading measures will block direct sunlight, prevent glare, make the indoor illumination distribution more uniform, and help the normal work of vision. For the surrounding environment, the sunshade can disperse the reflected light of the glass (especially the coated glass) of the glass curtain wall, and avoid the light pollution caused by the reflection of the large area glass. However, because the sun-shading measures have the effect of blocking light, it will reduce the indoor illuminance, which is even more unfavorable in rainy days. Therefore, full consideration should be given to the design of the sunshade system to meet the requirements of indoor natural lighting as much as possible.

    4. The effect of shading on the appearance of the building. Most people think that glass curtain wall design can only be flat-paneled, and it is impossible to design external shading facilities, but from many foreign cases, we can find that metal glass curtain wall can be designed into a beautiful shading form with lightweight metal plates and become an interesting part of architectural modeling. Part. The shading system forms a light and shadow effect on the glass wall of the glass curtain wall, which reflects the aesthetic effect of modern architectural art. Therefore, in the European architectural world, the external shading system has been used as an active facade element, even called the double-layer facade. The first floor is the facade of the building itself, and the other is the facade form of dynamic shading. This kind of "dynamic" building image is not because of the fashion needs of the building facade, but a new modern architectural form produced by modern technology to solve the human demand for building energy saving and enjoying nature.

    5. The effect of shading on room ventilation. Shading facilities have a certain blocking effect on room ventilation. When the windows are opened for ventilation, the indoor wind speed will be reduced by 22-47%, depending on the structure of the shading facilities. However, it has a blocking effect on the hot air rising on the glass surface, which is not good for heat dissipation. Therefore, attention should be paid to the structural design of the sunshade.
