摘要
结合内蒙古地区气候区域划分、变电站建筑结构特点及能耗特征,应用EnergyPlus软件对典型变电站主建筑进行建模,通过对变电站建筑窗墙面积比、外窗及外墙传热系数、换气次数等建筑能耗影响因素进行关联分析,得到了其与建筑采暖负荷的相关性关系,并得出了以下结论:内蒙古地区3种不同类型变电站建筑的供暖负荷由大到小依次排序为全户内站、半户内站、户外站;5个参数单个变化时窗墙面积比和外窗传热系数的增加与供暖负荷的增加基本成线性关系,而外墙传热系数和换气次数的增加与供暖负荷的增加基本成指数增加关系;以及在增加外窗传热系数的同时减少窗墙面积比,能够同时起到采光与节能效果。并给出了内蒙古地区变电站建筑节能优化建议措施。
Combined with the climate regional division, substation building structure characteristics and energy consumption characteristics in Inner Mongolia, the main building of typical substation is modeled by using EnergyPlus software. Through the correlation analysis of the influencing factors of building energy consumption such as window wall area ratio, external window heat transfer coefficient, external wall heat transfer coefficient and ventilation times of substation building, the correlation between those factors and the building heating load are obtained. The heating load of three different types of substation buildings in Inner Mongolia is ranked as whole indoor, half indoor and outdoor station from largest to smallest.When the five parameters change individually, the increase of window wall area ratio and external window heat transfer coefficient is basically linear with the increase of heating load, while the increase of external wall heat transfer coefficient and ventilation times is basically exponential with the increase of heating load. Besides, increasing the heat transfer coefficient of the external window and reducing the window wall area ratio can achieve the effects of daylighting and energy saving at the same time. Some suggestions and measures for energy saving optimization of substation buildings in Inner Mongolia are also given in this paper.
