Numerical simulation and thermal comfort analysis of indoor air distribution in large space buildings

Numerically simulates the velocity field and the temperature field in large space buildings separately adopting register sidewall air supply and sidewall return, nozzle outlet sidewall air supply and sidewall return, diffuser ceiling air supply and below return, stratificated air conditioning and displacement ventilation, and verifies the results by experiments. Based on the index of ADPI, evaluates these air supply methods in thermal comfort. The results indicate that stratificated air conditioning and displacement ventilation are better modes for air conditioning in a large space buildings．
