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.
