The Manufacturer Of Fireproof Door Adopts Removable Sunshade Device

Permanent is to set various forms of sun visors in the fire door manufacturer; Temporary is to set light cloth curtains, bamboo curtains, soft shutters, canvas tents, etc. in the window. The sunshade of the window can be made into individual or continuous, depending on the size of the window and the combination of windows. 5. In the permanent sunshade, the movable sunshade can be divided into fixed and movable according to whether its components can be moved or disassembled. The movable sunshade can adjust the angle of the sunshade arbitrarily according to the change of seasons in a year, the change of time in a day and the cloudy and sunny conditions of the sky; In cold seasons, it can also be removed in order to avoid blocking the sun and strive for sunshine. It is more flexible and ideal in use.

Therefore, in recent years, sunshade has been widely used in buildings at home and abroad. Influence on indoor air temperature of fire door manufacturer according to the observation data of Guangzhou test house, the influence of shading on indoor air temperature is shown in Figure 8. The test condition is that the conditions of the two rooms are the same. A window without sunshade is set outside the window of the room. The observation is carried out under the conditions of opening and closing the window respectively. As mentioned above, shading has a favorable effect on blocking direct sunlight and preventing indoor overheating or local overheating in summer. At the same time, it also has an adverse impact on the ventilation and daylighting of the room. Sun shading design also involves regional climate characteristics, solar terrestrial relative operation law, general layout and orientation of buildings, use of rooms or health requirements, etc. This is a complex and comprehensive problem, which must be fully considered in design. This paper puts forward the sun shading design principles of general civil buildings under the condition of open windows and natural ventilation, so as to create certain conditions for comprehensively considering the sun shading design. 1. Considering the regional climate characteristics, the time and mode of sun shading will be different due to the different climate characteristics of each region. 2. For areas where the winter is cold, the season is not hot, and the winter is much longer than the summer, the sunshine is mainly sought in a year, and there is generally no need to set up sunshade in summer. For areas where winter is cold, summer is hot and winter is longer than summer, because the time of shading is not long in a year, temporary light sun thanks such as curtains, bamboo curtains, soft shutters and tents are generally used as publicity. For areas with cold winter, hot summer and similar length of time in winter and summer, the problem of sunshine in winter is more prominent because of the need for sunshine in summer.

Therefore, it is appropriate for the fire door manufacturer to adopt the removable sunshade device, at least the movable sunshade should be adopted, and the fixed sunshade is not appropriate. For areas with warm winter, hot summer and much longer summer than winter, due to the long time of shading in a year, it is generally appropriate to adopt permanent movable or fixed shading, especially movable shading. Of course, for these areas that need shading, greening and combined treatment of walking and building components can generally be used to solve the shading problem Considering the general layout of the building, on the premise of striving for the dominant wind direction in summer, in order to prevent the room from being affected by strong solar radiation in summer, the room should avoid east-west direction as much as possible, and at least avoid opening large windows in west direction as much as possible. Because in hot summer, the solar radiation heat penetrated through the window per unit area is about 1.6 ~ 1.9 times more in the east-west direction than in the south direction; The east-west direction is about 2.0 ~ 2.5 times more than the north direction. From the depth of the sun shining on the room, the east-west direction is much larger than the north-south direction. Especially in the west facing room, when the sun shines through the west window, it is the time when the indoor temperature is high. If the human body is exposed to solar radiation at this time, it will feel hot and uncomfortable.
