Data for: A general model for predicting the airflow rates of a vertically installed solar chimney with connecting ducts

Contains the excutable file for the calculation of solar chimney airflow rates. It applies to the vertical, square type of solar chimneys. It is an improved and expanded version of version 3. The updated excutable file is able to calculate when the heat input in the chimney chanell q=0. In this inverse condition, it is assumed that the air enters the chimney channel from the room and thus the density of the chimney channel is the same as that in the room. The new exe file also improves in the searching method for solutions or optimal values.本数据集包含用于计算太阳能烟囱（Solar Chimney）气流速率的可执行文件（executable file），该文件适用于立式方形太阳能烟囱。其为第3版的改进扩展版本：更新后的可执行文件可在烟囱通道热输入量q=0的工况下开展计算，在此反向工况中，假设空气从房间流入烟囱通道，因此烟囱通道内的空气密度与房间内空气密度保持一致。此外，新版可执行文件还优化了求解或最优值的搜索算法。
