Mechanism of Indoor Vertical Temperature Profile in Nature Ventilation Building Numerical Calculation on Vertical Temperature Profile with Block Model

摘要

Using chimneys for natural ventilation is considered as an effective way to save energy in summer and intermediate seasons. However, the effect of the chimney on indoor thermal environment in wintertime still remains unknown well. In this study, an environmental measurement and a simple mathematical model is applied to figure out whether the indoor vertical temperature difference in wintertime is due to the chimney's open state or it's affected by some other factors.
