摘　　要：随着建筑节能工作深入,建筑智能遮阳技术迅速发展,外遮阳智能控制系统成为有效降低建筑能耗、提高能源利用效率的新兴节能技术。通过建筑外遮阳百叶智能控制系统的对比设计,采用EnergyPlus的EMS模块进行模拟,比较东向百叶外遮阳不同智能控制方式对室内能耗的影响,对百叶最优倾角常开、入射角控制、冷负荷控制、综合控制进行能耗分析。研究结果发现:3种百叶控制方式与百叶最优倾角常开状态对比均有一定的节能效果,仅有入射角控制这一方式的总能耗最低,综合控制次之,仅有冷负荷控制的方式能耗最高。研究结果为建筑设计者提供了关于东向百叶外遮阳智能控制系统设置的参考,通过优化入射角控制设置降低能耗、提高建筑舒适性。As energy-saving efforts in construction deepen,intelligent sunshading technology in buildings has rapidly developed,with external sunshading intelligent control systems emerging as a new and effective energy-saving technology to reduce building energy consumption and improve energy utilization efficiency.External sunshading louver intelligent control systems are simulated with the EnergyPlus EMS module.By comparing the influence of different intelligent control methods for east-facing louver external sun shading on indoor energy consumption,energy consumption is analyzed on louver optimal tilt angle constant opening,angle of incidence control,cold load control,and comprehensive control.The research findings show that all three louver control methods feature certain energy-saving effects compared to the louver optimal tilt angle constant opening state,with only angle of incidence control having the lowest total energy consumption,followed by the comprehensive control,and only cold load control having the highest energy consumption.The study results provide guidance for building designers on the settings of east-facing louver external sunshading intelligent control systems,suggesting that optimizing angle of incidence control settings can reduce energy consumption and enhance building comfort.
