摘要
采用数值模拟的方法,结合不同气流组织形式,模拟送风频率在三种低频正弦(0.3 Hz,0.4 Hz,0.5Hz)时对人体热舒适的影响,结果表明:0.3 Hz低频送风在上送下回、同侧上送上回、异侧上送上回形式下,0.5 Hz低频送风在下送上回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,可以更好的满足人们对舒适度的要求。
Per use numerical simulation to build models to simulate natural wind supply in a low-frequency wind speed （0.3 Hz, 0.4 Hz, 0.5 Hz）, combined with a different form of indoor airflow distribution, to analyze the impact of indoor thermal environmental fluctuations on human thermal comfort. The results show that 0.3Hz air supply in the airflow distribution such as up-inlet and down-outlet, up-inlet and up-outlet on the same side, up-inlet and up-outlet on the opposite side,0.4Hz in the airflow distribution of down-inlet and up-outlet can make the human thermal comfort better. The inlet and outlet set in the opposite sides and fluctuational airflow is sent directly to the human body location, reducing the air velocity and improving the supply air temperature, people can better meet the requirements of comfort.
