This airflow generation device comprises: an airflow generation unit (20, 30) that generates an airflow; a duct (91) that guides the airflow generated by the airflow generation unit to an outlet (911, 912) for blowing the airflow toward the occupants in the passenger compartment of a vehicle; and a control unit (80) that controls duty ratio which is the ratio of the frequency of pulse voltage to be applied to the airflow generation unit to the pulse width of a pulse period of the pulse voltage, and intermittently blows out the airflow from the outlet.

    空气流产生装置具备:产生空气流的空气流产生部(20、30);将由所述空气流产生部产生的所述空气流向朝向车辆的车室的乘员吹出该空气流的吹出口(911、912)引导的管道(91);以及控制部(80),该控制部控制施加于所述空气流产生部的脉冲状的电压的频率和所述脉冲状的电压的脉冲宽度相对于脉冲周期的比即占空比,从而从所述吹出口间歇地吹出所述空气流。
