The effect of relative humidity on the number concentration of aerosol particles in a sealed volume

Investigates the effect of the increase in relative humidity on the change in the number concentration of fine particles suspended in the air in a closed sealed volume. This work was carried out within the scope of a series of works of the SIRIUS international project. The project is aimed at studying the dynamics of aerosol accumulation in the air environment of a sealed inhabited object using methods for assessing the level of aerosol contamination used in cleanroom technology. A qualitative result of the relationship between the number concentration of the airborne particles and the relative humidity inside the sealed volume in the absence of other sources of particle generation was obtained. This result correlates with the experimental data obtained during the SIRIUS four-month isolation experiment and lays the foundation for preparing for new isolation experiments of the SIRIUS project.
