摘要:
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．
Abstract:
The present paper discussed the analysis on sensitivity and matching relations of critical design parameter of night ventilation buildings by means of numerical simulation. Firstly, a building model is set up in energy simulation software Energyplus based on the information of experiment al building. The accuracy of model was validated by the comparison of simulation result s and experiment data. Then, the effects of ventilation opening, ventilation rate and thermal storage capacity on indoor thermal environment were analyzed. the results show that 1) the ventilation rate is nearly linear with ventilation opening for the model in this paper; 2) it is not true that the bigger opening makes the better indoor thermal environment, and there is an optimum opening size in a certain heat storage capacity; 3) there is a nice logarithmic relationship between heat storage capacity and indoor thermal comfort; 4) the match relations between ventilation and heat storage capacity, and optimum ventilation with different heat storage capacity have been derived through a lot of numerical simulation
