Glass curtain wall

Abstract

The invention discloses a glass curtain wall which comprises single-layer glass arranged on the outer side and double-layer hollow glass arranged on the inner side. A first permeable plate is arranged at a gap between the single-layer glass and the double-layer hollow glass. A second permeable plate is arranged between the double-layer hollow glass and a wall. The single-layer glass located below the first permeable plate is composed of a plurality of first glass louvers. The double-layer hollow glass located below the first permeable plate is composed of a plurality of second glass louvers. The first glass louvers and the second glass louvers are connected with a motor through transmission mechanisms. The motor is controlled by a controller. The glass curtain wall can achieve heat preservation in winter, heat protection and heat insulation in summer and indoor ventilation.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a glass curtain wall. Background technique [0002] As the main enclosure component of the building, the glass curtain wall is not only a key part affecting energy consumption, but also an important factor affecting indoor comfort. In hot summer and cold winter regions, the glass curtain wall should meet the needs of winter heat preservation and summer heat protection and heat insulation at the same time. However, the existing glass curtain walls often have a single function and cannot simultaneously meet winter heat preservation, summer heat protection, heat insulation, and indoor Ventilation. [0003] The ventilation system of the existing "double-skin" glass curtain wall has three structures: external circulation natural ventilation glass curtain wall, external circulation mechanical ventilation glass curtain wall, and internal circulation mechanical ventilation gl...

figure 1 It is a schematic diagram of the structure of the external circulation natural ventilation glass curtain wall. The air in the channel is heated by the outdoor solar energy, and flows upward under the action of buoyancy, and finally flows out from the air outlet to the outside. The continuous flow of air in the channel takes away the heat and reduces the The temperature of the outer surface of the inner curtain wall glass reduces the heat transfer to the room, and ultimately reduces the consumption of cooling energy. However, the structure has poor thermal insulation effect in winter and consumes a lot of heating energy in winter, and the ventilation effect is average.

figure 2 It is a schematic diagram of the structure of the external circulation mechanically ventilated glass curtain wall. This structure is conducive to the exchange of indoor and outdoor air, and the gap between the inner and outer glass will be narrower, so fans will be used to assist ventilation. The single chimney effect can no longer satisfy the air in The need for circulation in the middle; although the structure has good thermal insulation effect in winter, it has poor heat release and heat insulation effect in summer, and the ventilation is not good

image 3 It is a schematic diagram of the structure of the internal circulation mechanical ventilation glass curtain wall, which is mainly used in winter to rely on mechanical means to draw indoor air into the interlayer, and use the relatively low temperature indoor air to cool the interlayer that heats up after absorbing solar radiation, reducing the heat of solar radiation Lost, although the structure has a good thermal insulation effect in winter, the thermal insulation effect is poor and the ventilation effect is poor
