Abstract
In this paper, it is proposed to use electric fan to actively control the indoor gas flow field to improve the ability of an air purifier to capture PM2.5 and other fine particles. For this purpose, an indoor physical model formed by a room, an air purifier and an electric fan is established and the simulation software Fluent is used to simulate the gas flow field distribution and PM2.5 particle tracking. The control method of the electric fan based on periodic rectangular wave is adopted to control and maintain the steady and conducive indoor gas flow field distribution for gathering particle pollutants into the air purifier’s inlet. The simulation results show that the active control method of gas flow field can improve the purification speed and effectiveness of air purifier, and the simulation results are verified by actual test of the purification process of PM2.5 particles in an enclosed room. It provides an economical, practical and effective method to improve indoor air quality.
