Embodiment 1

[0050] like figure 1 and image 3 As shown, a segmented sunshade system for large-space buildings, including a number of segmented sunshades that are arranged on each facade wall of a large-space building by rotating from top to bottom, a motor drive system that drives each section of sunshade to rotate, The time motor control system connected with the signal of the motor drive system, the time motor control system is based on the LONWORKS control network technology, and is used to drive the motor to rotate according to predetermined parameters at different times, thereby adjusting the rotation angle of each section of the sun visor to dynamically adjust the maximum The light environment in the space building interior.

[0051] In this embodiment, the segmented sun visor sections of each facade wall are three sections, including the upper sun visor 1, the middle sun visor 2, and the lower sun visor 3. Axis of rotation, wherein the axis of rotation located on the east and wes...

Embodiment 2

[0053] This embodiment needs to be based on the light and climate environment of the local area, so it is impossible to simulate and analyze each area one by one. The present invention takes Guangzhou area as an example, and based on the light and climate environment in Guangzhou area, divides and analyzes the large-space buildings (taking the training hall as an example) The indoor light environment under the control of the segmental shading system is simulated and analyzed to obtain the relevant parameters of the optimal segmented shading system.

[0054] A method for parameter optimization of the segmented sunshade system as described, comprising the steps of:

[0055] S1. Preliminary acquisition of the comfort range of illuminance when the people in the area where the large-space building is located have the best comfort; all countries in the world attach great importance to the quality of the indoor light environment of buildings, and have stipulated the minimum standard v...

Abstract

The invention discloses a segmentation sun-shading system for large-space buildings. The system comprises a plurality of segmentation sun shields rotationally arranged on various vertical walls of a large-space building from top to bottom, a motor driving system for driving the segmentation sun shields to rotate and a time motor control system which is in signal connection with the motor driving system; the time motor control system is used for driving a motor to rotate according to preset parameters at different moments on the basis of the LONWORKS control network technology, and therefore the rotating angles of the segmentation sun shields can be adjusted to dynamically adjust the luminous environment inside the large-space building. The invention further discloses a parameter optimization method used for the segmentation sun-shading system for large-space buildings. On the basis of the local regional climate environment, the luminous environment quality of the large-space building of the side interface lighting mode is optimized by controlling the rotating angles of the segmentation sun shields, the indoor lighting uniformity is improved, and the requirement of people for the comfortable luminous environment can be met at different seasons and different moments.

Description

technical field [0001] The invention relates to the field of building sunshading, in particular to a parameter optimization method of a segmented sunshading system capable of adjusting the indoor light environment of a large-space building. Background technique [0002] The lighting method of the large-space building is the best way of lighting the roof and the side interface together, but when the large-space building can only be illuminated through the side interface, the uniformity of indoor lighting often cannot meet people's needs for use and comfort. At present, most large-space buildings rely heavily on active lighting technology, resulting in a large amount of energy loss. If the uniformity of indoor lighting can be improved through building passive technology, it will be of great significance to building energy conservation. [0003] The dynamic changes of the outdoor climate environment are in conflict with the need for a relatively stable and comfortable indoor en...
