【 摘 要 】

As the unsatisfied environment of the fossil fired power plant become more controversial and disputable, the current tendency of enclosed coal yard which helps to decrease air pollution gains more application than those open ones. In order to improve the indoor environment and ventilation effect as well as to achieve good energy conservation at the same time, this paper investigates the ventilation effect of the roof vortex flow natural ventilator. By using multivariate nonlinear regression analysis and the theoretical calculation of natural ventilation, this paper proposes an instructive natural ventilation model and calculation method of enclosed coal yard based on the indoor pollutants concentration control, which is highly recommended as a good design application in similar enclosed coal yard buildings.
