变电站室内散热密度对围护结构节能性的影响

绿色节能是我国变电站建筑的发展目标,而变电站建筑功能多样且以主控室为代表的建筑具有较大的内热源,如何合理确定其围护结构保温隔热性能是实现变电站建筑节能的基础。针对典型变电站主控室建筑,采用DeST对其位于6个高寒地区时的围护结构总耗热量进行了计算分析,得到了不同室内散热密度条件下总耗热量指标随外墙传热系数的变化关系。研究结果将为高海拔寒冷地区变电站以主控室为代表建筑的节能设计提供一定的指导。

Influence of Heat Release Density in Converting Station Monitor Room on Energy Saving Performance of Building Envelope

Green and energy-saving is the developing goal of converting station building, which has functional diversity and room represented by monitor room has great inner heat source, therefore, how to reasonably determine its envelope thermal insulation performance is the basis of achieving energy saving. In this present study, as to typical monitor room, its total heat consumption of envelope was calculated and analyzed for six cities locating in high altitude cold region by using the DeST. Meanwhile, the variation relationship of envelope total heat consumption with its heat transfer coefficient was obtained under different indoor heat release density. The research results may provide certain guidance for monitor room energy saving design of converting station building in high altitude cold region.
