Numerical simulation and analysis of indoor thermal environment in four kinds of air supply mode

According to several models,which are in the same supply air temperature and speed but different air supply mode,by using CFD technology and Airpak software to do the numerical simulation,the paper studies the influence law of the indoor air quality and human thermal comfort in different kinds of airflow organization form.The results show: the simulation result is consistent WITH the experimental data,which shows the accuracy and reliability of Airpak software for simulating indoor thermal environment;and under the same air supply parameters and different air supply forms,the indoor air quality is very different;the lateral supply and downside return air mode is more comfort than others in the work area.
