温度调节单元(100X)包括第1进排气机(10A)、第2进排气机(20A)以及用于收纳被调温体(50)的壳体(30)。第1进排气机(10A)和第2进排气机(20A)分别包括:旋转驱动装置,其包括轴和使轴旋转的旋转驱动源;叶轮,其包括叶轮盘和动翼,所述叶轮盘在中心部与轴卡合,并具有沿与轴交叉的方向延伸的面,所述动翼为多个,自叶轮盘竖立设置;以及风扇罩,其包括进气口、环绕叶轮的周围的侧壁以及与壳体(30)的内部连通的送风口。多个动翼自叶轮盘的中心部朝向外周部以向轴的旋转方向突出的圆弧状延伸。第1进排气机(10A)所产生的声音的能量达到峰值的频率与第2进排气机(20A)所产生的声音的能量达到峰值的频率不同。

    Temperature conditioning unit (100X) includes first intake and exhaust device (10A), second intake and exhaust device (20A), and housing (30) that accommodates element (50) to temperature-condition. First intake and exhaust device (10A) and second intake and exhaust device (20A) each include: a rotary drive device including a shaft and a rotary drive source that rotates the shaft; an impeller including an impeller disk that engages the shaft at its central part and includes a surface extending in a direction intersecting the shaft, and a plurality of rotor vanes erected on the impeller disk; and a fan case including a side wall surrounding the impeller, an intake port, and a vent communicating with an interior of housing (30). The plurality of rotor vanes each extend in a direction from the central part to an outer peripheral part of the impeller disk in the shape of a circular arc bulging in a rotation direction of the shaft. A frequency at which first intake and exhaust device (10A) produces a sound having an energy peak is different from a frequency at which second intake and exhaust device (20A) produces a sound having an energy peak.
