摘要:
模拟研究多层建筑太阳能烟囱全年热压通风效果并进行通风潜力评价. 基于设计平台搭载的性能模拟工具Honeybee和RhinoCFD构建耦合模拟工作流,计算太阳能驱动下烟囱逐时通风量; 根据房间最小新风量要求、通风时长等因素计算单位时间有效流量,并定义为烟囱的通风潜力值; 选取南京某办公建筑双入口太阳能烟囱进行了案例研究. 结果表明:该太阳能烟囱全年逐月通风潜力值呈现出“M”形波动,潜力值较大主要集中在4～6月和9～11月,其中10月份达到最大的637.7 m3/h; 烟囱通风存在流量分配失衡现象,一层入口流量满足房间新风量要求的时长远大于二层; 对比发现,独立式烟囱可实现更均衡的流量配置. 单位时间有效流量能够较好反映多层太阳能烟囱的通风潜力; 相关研究方法与结论可为设计阶段的烟囱性能评估与优化提供参考.
Abstract:
The present work aims at studying the annual stack ventilation of solar chimney in multi-storey buildings and evaluating the ventilation potential. A simulation workflow coupling Honeybee and RhinoCFD, performance simulation tools on design platform, is proposed to calculate the hourly ventilation rate of chimney driven by solar energy. Then the effective hourly ventilation rate, which is defined as the ventilation potential value, is determined according to the ventilation duration and the minimum fresh air requirement of each room. A case study of a double-inlet solar chimney in an office building in Nanjing was carried out. The results indicate that the monthly ventilation potential value of the solar chimney shows a "M" shape fluctuation. The value is higher mainly from April to June and September to November, and reaches the maximum, 637.7 m3/h, in October. The phenomenon of flow distribution imbalance exists in the chimney, and the duration of the first-floor inlet flow meeting the requirements of fresh air volume is longer than that of the second floor. The comparison shows that the independent chimney can achieve more balanced flow configuration. The effective hourly ventilation rate turns out to be a useful indicator for multi-story chimney’s ventilation potential. The research method in this paper can provide reference for chimney performance evaluation and optimization in design stage.
