Research of Indoor Air Quality on an Air-Conditioning Classroom

摘要

Simulation and experimental study the IAQ(indoor air quality) of air-conditioning classroom in summer condition were carried out. With professional software FLUENT, research model of complicated three-dimensional turbulent flow-field that contained many kinds of ventilation equipments was established. The model visually simulated the changes of distributions of indoor air velocity and air age. The results of test verified the feasibility of numerical simulation method. On the present study condition, the change relation between location of air supply inlets and indoor air velocity, relative indoor air distribution in different heights was found. The study discussed the distances of air supply inlet to meet the demand of wind speed in human activity area. research results show that air volume had certain impact on the IAQ and thermal environment and provided guidance for building a comfortable, healthy thermal environment in the air-conditioning classroom.
