Movable sunshade shutter system used for building external window

Abstract

The invention discloses a movable sunshade shutter system used for a building external window. When an existing movable sunshade shutter system with arc-section shutters is used, the problems that scattered sunlight in gaps of the arc shutters is prone to being guided into a room, the distance between the inclined shutters is large, and vertical and horizontal steering sleeve ropes are used for controlling the gradient of the shutters are loose exist. The movable sunshade shutter system is characterized in that when in a horizontal state, all the shutters are mutually in parallel. When all the shutters are in a sunshade state, the adjacent shutters in the vertical direction are partially shaded with each other. A positioning plate is fixedly installed on a connecting node between the inner perpendicular steering sleeve rope and the lower horizontal steering sleeve rope. According to the movable sunshade system, the shutters are used for reflecting the sunlight in the gaps reversely and outwards in an arc mode, and through the improvement and guarantee of the gradient in the process of closing the shutters, the system has high shading performance, the heat insulation effect is effectively improved, and scattered solar radiation heat entering into the room through the external window is reduced.

Description

technical field [0001] The invention relates to the field of building sunshade, in particular to a movable sunshade louver system for building exterior windows. Background technique [0002] In regions with hot summer and cold winter in China (including regions with hot summer and warm winter), the energy consumption of building cooling due to summer solar radiation is very high, and it continues to increase with climate warming. affect people's lives and social and economic development. Installing sunshades on building exterior windows can reduce building cooling energy consumption in summer. At the same time, considering that the winter sunlight radiation through exterior windows can also reduce building heating energy consumption in hot summer and cold winter regions, setting movable exterior sunshades and central movable sunshades on building exterior windows is a good idea. It is the most effective measure to reduce the energy consumption of building air conditioners i...

AI Technical Summary

Problems solved by technology

When the existing arc-shaped louver movable sunshade system is used for shading, there are problems such as scattered sunlight at the gap of the arc-shaped louvers is easily introduced into the room, the distance between the inclined louvers is large, and the vertical and horizontal steering ropes that control the inclination of the louvers are relatively loose. , when the louvers are in the full shading position, the degree of closure between the louvers is not enough, more scattered sunlight enters the room, that is, the shading performance is reduced, and the heat insulation effect of the movable louver shading system is reduced, and the louver system with poor shading performance reduces the shading effect by 30 %above
