摘　　要：窗户是影响建筑供暖空调负荷的一个重要部分。通过窗户进入室内的热量包含温差传热和日射得热两部分,其中温差传热取决于建筑所在城市气象参数、窗户本身结构热阻,当建筑投入使用后将很难做节能优化,然而日射得热部分却可以后期人为干预。以成都地区某办公建筑为例,结合两种不同内遮阳行为调节方式,运用建筑全年动态负荷计算的手段,研究内遮阳行为调节对建筑全年耗能的影响。结果表明,当建筑采用内遮阳行为调节作用时,建筑全年耗冷量减少,耗热量与无遮阳时相同,建筑全年总的耗能减少;以室温控制作为调节方式,可使建筑全年总的耗能减少16%,结合地区太阳辐射分布作为调节方式,可相应减少7%;以室温作为内遮阳行为调节时,存在一个最优的温度区间,以太阳辐射分布调节时,其节能将与目标温度相关。The window is an important part that affects the heating and air conditioning load of buildings.The heat entering the room through the window contains thermal differential heat transfer and solar radiation heat gain.The temperature difference heat transfer depends on the meteorological parameters of the city where the building is located and the thermal resistance of the window structure.When the building is put into use,it will be difficult to optimize energy saving,but the solar radiation heat gain part can be artificially intervened in the later stage.Taking an office building in Chengdu as an example,the influence of internal shading behavior regulation on the building’s annual energy consumption is studied by combining two different internal shading behavior regulation and using the method of annual dynamic load calculation of the building.The results show that when the building adopts internal shading,the annual cooling consumption decreases,the heat consumption is the same as that without shading,and the total annual energy consumption of the building decreases.Using room temperature control as the regulation mode,the total energy consumption of the building can be reduced by 16%in the whole year,and by using the regulation mode of regional solar radiation,it can be reduced by 7%.When room temperature is used as internal shading behavior regulation,there is an optimal temperature range,and when solar radiation distribution is used as regulation,its energy efficiency will be related to the target temperature.
