Calculation of gas and particle concentrations in ventilated rooms with a non-steady rate of air pollution. Berechnung von Gas- und Partikelkonzentrationen in belufteten Raumen bei instationarem Schadstoffanfall.

Explains method for calculating time dependences and average values of gas and particle concentrations in ventilated rooms, which permits determination of air pollution propagation in a room by means of given target functions. Applies method forvarious ventilation rates. Provides calculated example of determination of gas concentration occurring in a room with a leaky gas container. Illustrates representative time functionfor different pollutants.
