Abstract

The finite element software FLUENT was used to study and analyze the flow characteristics of indoor particle concentration distribution in upper air supply buildings under different air supply parameters. Physical model and finite element model were established to calculate the concentration distribution of particulate matter, and to find the best air supply parameters and working conditions, so as to improve indoor air quality and comfort. Through the simulation calculation of indoor air flow field distribution and concentration distribution of fine particles under different working conditions, the optimal air supply parameters are obtained, that is, the temperature of the air supply outlet is 20℃, and the air supply velocity of the air supply outlet is 3m/s. The simulation calculation results in this paper provide certain design basis for determining the optimal air supply parameters in the subsequent reengineering.
