#Electric sun shade#

Impact on day lighting

The electric sunshade can block direct sunlight, prevent glare, make the indoor illuminance distribution more uniform, help the normal work of vision, and avoid light pollution caused by large-area glass reflection. However, since the sunshade products have the effect of blocking light, full consideration should be given to the design of the sunshade system to meet the requirements of indoor natural lighting as much as possible.

Effect on indoor temperature

Electric sun blinds have a significant effect on preventing indoor temperature from rising. Test data in a west-facing room shows that when the windows are closed, with or without electric sun blinds, the maximum difference in room temperature is 20 degrees Celsius, and the average difference is 1.4 degrees Celsius.

Moreover, the temperature wave amplitude of the room where the electric sunshade is installed is small, the time delay for the maximum room temperature to appear, and the indoor temperature field is uniform. Therefore, electric sunshade is one of the main measures to save energy.

Effect on solar radiation

Electric sunshade curtains can reduce direct sunlight and have a considerable effect on shielding the sun's radiant heat. The installation of electric sunshade measures in glass curtain wall buildings is even more effective.

Impact on ventilation

Electric sunshade has a certain blocking effect on indoor ventilation. When the window is opened for ventilation, the indoor wind speed will be reduced by 22-47%, and it will block the hot air rising on the glass surface, which is not good for heat dissipation. Therefore, in the electric sunshade scheme Attention should be paid when designing.
