Résumé

In general, buildings are composed of multiple rooms, and the structure of airflow might be regarded as a network. In this study, the authors develop a model that couples three-dimensional transient pollutant transport in a room into a flow network model, with the aim of calculating the three-dimensional transient concentration transition in a building composed of multiple rooms. In the coupling model, the air transports between each room are calculated using a flow network model. The three-dimensional transient pollutant transports between each element (e.g., contaminant generation point, opening, air outlet, and air inlet) are calculated using a method based on the response factor. The authors present the calculation method as well as examples of the simulation, and report on the results.
