Intelligent building sun-shading system and method

Abstract

The invention discloses an intelligent building sun-shading system which comprises electric sun-shading louvers (4), a driving controller (3), a small meteorological station (1) and a controller (2). Data acquired by the small meteorological station is computed to calculate and judge various working environments where each electric sun-shading louver is positioned and control requirements of each electric sun-shading louver in real time; and according to preset priorities, working states of the electric sun-shading louvers are controlled. According to the invention, the requirements of variation of the outdoor temperature of each sun-shaded position of a building, the outdoor wind and rain condition, the indoor energy consumption condition and indoor daylighting can be comprehensively considered; and on the premise of ensuring safety, the indoor photo-thermal environment is effectively regulated, energy consumption of the building is effectively reduced and indoor comfort of the building is improved. The invention also discloses an intelligent building sun-shading method.

Description

technical field [0001] The invention relates to an intelligent building sunshade system and method. Background technique [0002] Architectural shading has been widely used, and the important role played by architectural shading in regulating the heat of building solar radiation and the effect of indoor natural lighting has been widely recognized. The "Code for Thermal Design of Civil Buildings" requires that the sun-facing sides of buildings, especially the windows facing east and west, should take effective sun-shading measures; "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Both Energy-saving Design Standards and Public Building Energy-Saving Design Standards put forward clear requirements for building shading; Green Building Evaluation Standards require effective shading measures, such as adjustable external shading, to adjust the indoor light and heat environment. [0003] At present, fixed external shading and manual curtains are ...

AI Technical Summary

Problems solved by technology

[0003] At present, fixed external shading and manual curtains are the main building shading products, and electric shading products are gradually becoming popular, but the application of intelligent building shading systems is still relatively small, and the control methods are relatively backward, and the degree of intelligence is not high. expensive

The most commonly used building sunshade intelligent control system on the market now is generally based on one or several groups of sunshade louvers as the basic control unit, and each control unit is equipped with sensors for solar radiation, wind, rain, and sun angle tracking. The number is very large, and the control signals are often transmitted over long distances in the form of switching or analog quantities. The system wiring is complicated, there are many fault points, it is not easy to maintain, and it is easy to be interfered and has poor stability.

In addition, the commonly used building sunshade intelligent control system mainly relies on tracking the sun's trajectory for adjustment, focusing on energy saving, with little consideration for the comfort of the indoor light and heat environment, and manual intervention is relatively inconvenient
