Sunshade system Internal and external sunshade system
Sunshade systems are divided into internal sunshade and external sunshade according to their installation position relative to the building wall. External sunshade is a device installed outside the transparent enclosure of the building to block sunlight.
Exterior shading is to use some physical method to block solar radiation heat and solar rays from entering the room through the building envelope. The modes of heat transfer include heat conduction
heat convection
and heat radiation. Since the energy transfer of solar radiation is mainly thermal radiation, we focus on studying the impact of thermal radiation on the indoor environment. When the sun radiates, it appears in the form of light, which is divided into three main bands: infrared rays, visible light, and ultraviolet rays. Among them, ultraviolet rays account for the entire heat, visible light accounts for it, and infrared rays account for it.
Text The above energy consumption of buildings is the energy consumption of air conditioning. Half of the energy consumption of air conditioning is due to the loss of doors and windows. Therefore, the sun shading of doors and windows of buildings is of great significance.
Text External shading is an effective method of building energy-saving design to block solar radiation heat from entering the room and avoid indoor heat loss in winter in areas with hot summer and cold winter
in areas with hot summer and warm winter, especially in summer. First, the external sunshade device can simultaneously improve the thermal comfort and light comfort of residence.

Text Real exterior sunshade must meet the three conditions of sunshade, heat insulation, light transmission, view, ventilation and breathability. Only when these three conditions are met at the same time can it be a real exterior sunshade. shade.

Sun Shade Classification

Text
Leaf flaps include aluminum alloy flaps, glass flaps, solar flaps, etc. The disadvantage is that they require integrated construction when the building is newly built. the cost is too high.

Venetian blinds
Including electric blinds and manual blinds, the disadvantages are that they are easy to collect dust, block the view when blocking the sun's rays, are easily deformed and damaged, are difficult to maintain, and have reliable mechanisms. The resistance is not high and not suitable for high-rise buildings.
Exterior hard roller blinds include aluminum alloy hard roller blinds, aluminum alloy foam hard roller blinds, plastic steel hard roller blinds, hard roller blinds and other wood materials. The disadvantages are that they also block light when shading, and they are not transparent, airtight, and style. Single and unattractive.
Text External soft roller blinds include electric soft roller blinds
Crank
The disadvantage of rocker-driven soft roller blinds and bead-driven soft roller blinds is that the wind resistance performance cannot be guaranteed when used outdoors.
Text Awnings include curved-arm awnings, swinging awnings, diagonal awnings, folding awnings, fixed awnings and track-type awnings. The disadvantages are high cost, low mechanical reliability and wind resistance. The effect is poor and not suitable for high-rise buildings.
Text Yang membrane structures include inflatable membrane structures and tensioned membrane structures.

Advantages of external sunshade products require light transmission, low carbon, energy saving, green environmental protection, sunshade insulation, wind resistance, pressure resistance, fire retardant, self-cleaning, easy to clean, fashionable and beautiful, etc. In summary, products that can meet the requirements It can only be a wind-resistant exterior sunshade product for high-rise buildings with excellent wind resistance and flame retardant properties, because its wind resistance and fire resistance can meet all requirements.
