Studies the impact of low-frequency (0.3, 0.4, 0.5 Hz) air supply with different air distribution forms (up-inlet and down-outlet, down-inlet and up-outlet, up-inlet and up-outlet on the same side, up-inlet and up-outlet on the opposite sides) on human thermal comfort by numerical simulation. The results show that 0.3 Hz frequency air supply in the air distribution forms of up-inlet and down-outlet, up-inlet and up-outlet on the same side, and up-inlet and up-outlet on the opposite sides, and 0.5 Hz in the air distribution form of down-inlet and up-outlet can make the human thermal comfort better. By setting inlets and outlets in the opposite sides and supplying fluctuation airflow to human body location directly, reducing supply air velocity and improving supply air temperature, better human thermal comfort can be obtained.
