First, when the building has higher standards, the following conditions should be used to meet the requirements of 1 to 2:
a indoor (outside) temperature reached or exceeded 29 ° C;
b solar radiation intensity > 240kcal / m2 · h (1004.6kJ / m2 · h);
c sunlight exposure indoor depth > 0.5m;
d Sun exposure indoor time exceeds 1h.
Second, the awning is suitable for sunshade outside the door window of low-rise, multi-storey buildings. It should not be used outside the high-rise building.
Third, the material, thickness, size and form of the sunshade material, the form and specifications of the fixing device, the power of the motor (when electric is used), and the magnitude of the wind pressure at the place of use are related to each other. In the case, obtain relevant technical information from professional manufacturers and select them after comprehensive consideration.
Fourth, the connection between the shading system and the building main body, lightning protection measures and other safety-related issues need to be determined and determined by the engineering designer according to the specific project conditions.
Fifth, when choosing a shading system with a roller blind box, the effect of different positions of the roller blind box on the wall energy saving should be considered.
Sixth, for systems equipped with automatic control, it is generally required to install wind control and rain control sensing devices, and light control can be selected according to specific conditions. Manual drive is generally not suitable for external shading in unmanned locations.
Seventh, the fabric is recommended to use dark color (or the dark side of the fabric facing the outside) to achieve a better shading effect.
Eighth, the performance requirements of the fabric:
a fabric should ensure a constant size and no deformation.
b The surface of the fabric is smooth and smooth, ensuring free winding, preventing the fabric from running off, wrinkles or unwinding.
The c fabric should have sufficient tensile and tear strength to prevent the risk of tearing in harsh weather conditions.
The connection between the d fabrics should be done by a hinged welding process to ensure that the fabric has sufficient strength.
The e fabric should be guaranteed to have good color stability.
The surface of the f fabric should have certain anti-pollution properties, and it is easy to clean and easy to maintain.
Ninth, fabric types: polyester fabric, glass fiber fabric.
