ANALYSIS AND MODELLING OF INDOOR PARTICLE MATTER POLLUTION AND IMPACT OF AN AIR PURIFIER

Abstract

Following the economic, industrial, and social rapid development, the last 50 years has brought significant improvements in the materials and products aimed for indoor use, people remain exposed to various harmful materials and pollutants. Furthermore, technology is steadily moving towards higher efficiency and lower emissions. However, it is important to note that in some developing countries, and metropolitan cities face issues with ambient air pollution which ultimately infiltrates indoors and reduces the indoor air quality. The quality of the indoor air can be further hindered by various indoor pollution sources. In this paper a model of indoor air pollution is developed. The developed model is based upon mass conservation equation and is used to simulate indoor air pollution with particles of diameter lower than 2.5µm (PM2.5). Additionally, the model includes the effects of an air purifier in a given room. An analysis on the impact of the air purifier on some of the coefficients in the model is also presented. A verification experiment for the model is defined, and the model is successfully verified.
