Abstract

The CFD software was employed to simulate numerically the indoor airflow distribution in an air-conditioned room with different air supply temperature (20, 22, and 24 °C) and velocity (2, 3, 4, and 5 m/s). The results show that the simulation result is consistent with the experimental data, which shows the accuracy and reliability of CFD software for simulating indoor thermal environment. Specifically, the indicators including temperature, velocity, PMV-PPD, and mean air age are used in the analysis of the differences caused by the varied air supply velocity and temperature on the human thermal comfort. The comparisons show that the optimal air supply condition is the temperature 22 °C and the velocity of 3 m/s.
