FIG. 1 Experimental setup. The upper part shows the measurement room seen from above, and the lower right part shows the sampling system. Generated particles were first neutralized and emitted to the ventilation duct through which they entered the room. Particles were sampled both within the room with well-mixed air and where the aerosol entered the room.
FIG. 2 Measured particle number size distributions during the steady-state (from 5 to 21 h; Figure 3) of the F1 experiment.
FIG. 3 Upper part: measured number concentrations of particles with diameters between 200 and 400 nm during the F1 experiment (a typical experiment). Lower part: ratios of the measured number concentrations for the same size section for all experiments.
