Formula Revision of Natural Ventilation Driven by Hot Pressure in Single Large Window Opening

This paper investigated the natural ventilation driven by hot pressure on a typical office building with single window opening.The actual result indicates that the ventilation rate of natural ventilation driven by hot pressure in the actual single window opening construction is very different from that obtained by the theoretical formula,since the ventilation conditions between actual environment and ventilation driven by hot pressure in the single window opening are different.Therefore,the theoretical formula is amended,and it becomes more consistent with the actual ventilation rate of natural ventilation driven by hot pressure under conditions that the construction is in the form of single window opening.
