Research On Intelligent Louver Control Method Based On Building Energy Consumption Evaluation

With the rapid development of urbanization,the shortage of resources faced by human beings has become increasingly prominent.At the same time,the number of new office buildings has increased dramatically,and its energy consumption has also increased.In the total energy consumption of office buildings,artificial lighting energy consumption and air conditioning energy consumption account for a large proportion.The use of sunshade louver equipment can reduce the solar radiation entering the room and reduce the energy consumption of the air conditioner.However,the sunshade equipment also affects the natural lighting in the room and improves the energy consumption of the artificial lighting.The louver angle of the sunshade is used to reach the building.Energy conservation is very necessary.Therefore,based on the climatic characteristics of the hot summer and warm winter zone in Guangzhou,this topic studies the development trend of the sunshade facilities in the future-the intelligent blinds with adjustable blade angles,and explores the design principle and control method of the intelligent louvers,so that the intelligent louvers can be based on In outdoor weather conditions,the louver angles are adjusted correspondingly to the indoor and outdoor illuminance.The louver control strategy is developed according to different working conditions to achieve energy saving.The research contents are as follows:This paper first analyzes the calculation method of indoor solar radiation heating and indoor natural light distribution after the installation of sunshade louvers,and clarifies the factors affecting indoor light environment and thermal environment by sunshade louver,and divides the influencing factors into static influencing factors.Influencing factors and external influence factors.Then we propose the comprehensive energy consumption of lighting and cooling to measure the impact of these variables on building energy consumption,and use EnergyPlus software to build models to simulate different static factors such as louver width,louver spacing and louver material,and finally determine the most energy-efficient for Guangzhou area.The louver system design parameters.The model is used to explore the influence of louver inclination on the comprehensive energy consumption of building lighting and air conditioning.The energy saving effect of fixed angle louver and adjustable angle louver is compared,and the energy saving potential of adjustable angle louver is verified.Secondly,under the premise of comprehensive consideration of lighting energy consumption and air conditioning energy consumption,the fuzzy control method is used to develop an intelligent control strategy for the adjustable angle louver.The fuzzy control system adopts the hierarchical multi-rule set structure,and uses the outdoor temperature as the basis for judging the summer,excessive season and winter working conditions.Under different working conditions,the dual fuzzy controller is set to set the indoor illumination,the actual indoor illumination and the setting.The difference between the illuminance,the solar altitude and the outdoor skylight mode are set as input variables,and the louver dip is used as the output variable.Different fuzzy control rules are set for each working condition,and the air conditioning is reduced as much as possible under the premise of ensuring lighting conditions.Energy consumption;and set the fuzzy controller in Matlab,and simulate the fuzzy control system in Simulink,verifying the feasibility of the intelligent louver control strategy;Finally,in order to verify the rationality and practicability of the intelligent louver control strategy,this paper based on the comprehensive energy consumption analysis of lighting and air conditioning,finds the energy-saving reasonable area in the louver dip angle,and puts forward a judgment method of whether a louver dip angle is in the energy-saving rationality.If the louver angle of the output of the intelligent louver control system is not a reasonable energy-saving area,this paper also proposes an optimization method and calculation process,and takes the control strategies of the four chapters of summer,over-season and winter as the analysis case.Gradually optimized calculations.
