Background
For glass curtain wall buildings, the heat entering the room through the glass occupies a large proportion of the building heat. For such buildings, the heat gain of the building can be reduced by means of sun shading. The inner shading mode (such as curtain) in the shading means keeps the aesthetic feeling of the appearance of the building, but most of the absorbed solar radiation is radiated to the indoor space through the convection heat exchange.
There is a flexible thin-film solar electric curtain which converts light energy into electric energy by attaching a solar cell sheet to the curtain, and is used for a motor and electric equipment. Meanwhile, the curtain is controlled to lift and open and close according to the external environment so as to adjust the indoor light and temperature, and the effect of reducing the energy consumption of the building is achieved. However, this solution places the curtain indoors. After solar radiation enters the room, one part of the solar radiation can be converted into electric energy, the other part of the solar radiation enables the temperature of the curtain to rise, heat is transferred to the room through air convection heat exchange, and the heat insulation effect is poor.
