Characteristics of Indoor Particle Pollutant Distribution in Energy Conversation Building
Abstract: The objective of this paper is to investigate the concentration distribution of particle pollutants in air conditioning buildings. A diffusion model for indoor pollutants of all air conditioning was built. The effects of fresh air, outdoor pollutants concentration, filtration efficiency of fresh air, and return-air by-pass coefficient on indoor concentration distribution were discussed. The result shows that primary return air has critical filtration efficiency and the effect of fresh air ratio on indoor air quality is greater than by-pass coefficient in secondary return-air system.
