本文运用数值模拟分析方法对夜间通风建筑的关键设计参数进行了灵敏度和匹配关系分析.首先,以实验建筑为原型,利用能耗模拟软件Energyplus建立了一栋实际建筑的分析模型,通过室内空气环境数值模拟结果与实测结果的比较验证了数值模型的准确性.随后,探讨了通风开口面积、通风量和蓄热量对室内环境的影响,研究结果表明:1)对于本论文的模型,窗口面积和通风量近似呈线性关系;2)在特定的蓄热量下,窗口面积并非越大越好,存在使室内环境最舒适的最佳窗墙面积比;3)蓄热量与室内舒适度之间有良好的相关性,两者成对数关系;4)通过大量的数值模拟,得到了通风量和蓄热量之间的匹配关系图,并由此获得了每种蓄热量情况下的最佳通风量.
In this paper, the numerical analysis method is used to analyze the sensitivity and matching relationship of the key design parameters of nightly ventilated buildings.Firstly, based on the experimental building, Energyplus is used to build an analysis model of the actual building through the indoor air environment The numerical simulation results verify the accuracy of the numerical model.Secondly, the effects of ventilation opening area, ventilation volume and heat storage on the indoor environment are discussed. The results show that: 1) For the model, window area and Air volume is approximately linear relationship; 2) under a specific heat storage, the window area is not as large as possible, there is the most comfortable indoor window wall area ratio; 3) between the heat storage and indoor comfort good The relationship between the two is a logarithmic relationship; 4) Through a large number of numerical simulation, the matching relationship between ventilation and heat storage is obtained, and the best ventilation for each heat storage is obtained.
