Problems solved by technology

However, it can only play a simple shading effect. While achieving the shading effect, it does not fully consider the comfort of the indoor light environment of the building. It can only control the amount of light entering the room by simply blocking a part of the sunlight. However, this shading method is often It will affect the lighting conditions in the building interior

Embodiment 1

[0049] refer to figure 1 , 2As shown, the present embodiment provides a multi-layer retreating sunshade system, including a building glass curtain wall 3, a sunshade device and a controller 6, the sunshade device is installed on the outside of the glass curtain wall 3, and the sunshade device includes a multi-layer horizontal sunshade horizontal arrangement Plate 1, one end of each sunshade horizontal plate 1 is fixed on the glass curtain wall 3, and the other end is rotatably installed with a sunshade rotating plate 2, and the rotation angle range between the sunshading rotating plate 2 and the upper surface of the sunshading horizontal plate 1 perpendicular to 90°--90°, the outside of the glass curtain wall 3 is equipped with a sun angle detection device 5, and the controller 6 controls the rotation angle of each sunshade rotating plate 2 in real time according to the detection signal of the sun angle detection device 5.

Embodiment 2

[0057] This embodiment takes Shenzhen as an example to describe in detail the sunshade effect of the sunshade system of the present invention.

[0058] The multi-layer retreating sunshade system described in Embodiment 1 is applied to the outside of a certain building glass curtain wall 3 in Shenzhen area, and the facade at 2.8m-3.5m is selected as the laying layer of the sunshade device. The maximum overhanging size of the sunshade device ensures that no direct sunlight enters the area with a depth of more than 1m at 12:00 noon in spring, summer and autumn; the maximum outward rotation angle of the sunshade rotating plate 2 ensures that: in this state, Shenzhen’s autumnal equinox day at noon 12 The sun at :00 can just be reflected to the edge of the upper sunshade horizontal plate 1 through the edge of the lower sunshade rotary plate 2, and the maximum inward rotation angle of the sunshade rotary plate 2 ensures that: in this state, the sun is just completely dark through the ...

Embodiment 3

[0086] refer to Figure 21 , this embodiment discloses a multi-layer retreat sunshade control method, comprising steps:

[0087] S1, the sun angle detection device 5 detects the irradiation angle of the sun in real time, and transmits the detected irradiation angle signal to the controller 6;

[0088] S2. The controller 6 controls the rotation angle of each sunshade rotating plate 2 according to the irradiation angle signal detected by the sun angle detection device 5 .

Abstract

The invention relates to a multi-layer retreating sunshade system and its control method. The system includes a building glass curtain wall, a sunshade device and a controller. The sunshade device is installed on the outside of the glass curtain wall. One end of the sunshade horizontal plate is fixed on the glass curtain wall, and the other end is rotatably installed with a sunshade rotating plate. The sun angle detection device is installed on the outside of the glass curtain wall. The controller controls each sunshade rotating plate in real time according to the detection signal of the sun angle detection device. of rotation angle. The present invention can automatically and real-time adjust the rotation angle of the multi-layer sunshade rotating plate according to the angle of the sun on the premise of the minimum obstruction of the field of view to control the amount of incoming light, and convert part of the direct light through the diffuse reflection of the surface of the sunshade horizontal plate material In order to diffuse light into the room, so as to achieve building energy saving and provide a comfortable light environment effect, under typical working conditions, the system can reduce uncomfortable illumination by 300% to 600%, and reduce annual energy consumption per unit area by 36%.

Description

technical field [0001] The invention relates to the field of building sunshade, in particular to a multi-layer retreating sunshade system and a control method thereof. Background technique [0002] The indoor natural light environment has a positive impact on human activities. There is a relatively complete evaluation system for the evaluation of the indoor light environment, but the impact of the shading design on the indoor light environment is still rarely considered in the actual sunshade or facade design. [0003] At present, research on shading systems mainly focuses on shading control and the impact of shading on energy consumption, and seldom considers control, energy consumption, and indoor light environment at the same time. In shading design, shading types are mainly divided into static shading and dynamic shading. Under complex weather conditions, dynamic shading tends to be more adaptable and adjustable than static shading. The research in the field of static ...
