| Abstract: | The indoor diffusion process of radon is related to pollution of particles(aerosol).The airflow of air conditioning makes a great influence on the radon and particles.In this paper,the sources and characteristics of the indoor radon pollution and particles,the spread mechanism and the way to eliminate radon and its daughter are described.The effect of the ventilating air conditioning system to the transmission of indoor radon and radon dOcthter,the dynamics model of radon transfer in the air are analyzed.The numerical simulation method of radon and particle pollution process in ventilation room are compared and analyzed.The key problem of radon and particles pollution and numerical simulation under air conditioning environment are brought forward. |
