动态条件下不同气流组织形式对人体热舒适的影响

Impact of different air distribution forms on human thermal comfort under dynamic conditions

采用数值模拟的方法研究了低频(0.3,0.4,0.5Hz)送风结合不同气流组织形式(上送下回、下送上回、同侧上送上回、异侧上送上回)对人体热舒适的影响,结果表明:0.3Hz低频送风在上送下回、同侧上送上回、异侧上送上回气流组织形式下,0.5Hz低频送风在下送上回气流组织形式下气流波动对人体的热舒适影响较好,且送、回风口设置在异侧并将波动气流直接送至人体所在位置,减小送风速度,提高送风温度,可以更好地满足人们对舒适度的要求。

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.
