路20の流量調整弁21の開度を制御する。In an automobile air conditioner equipped with a temperature fluctuation device for blown air of this example, when the difference between the indoor temperature detected by the indoor temperature detector 16 and the preset indoor temperature is within a preset range, temperature variation control is performed. The device 23 selects the seat that the orientation detector 36 outputs and the seating detector 37 outputs, and the blown air temperature detected by the blown air temperature detector 35 of the seat changes with time. In order to do so, the heat generation amount regulator 33 of the heating device 34 for the seat and the opening degree of the flow rate adjustment valve 21 of the cold air passage 20 are controlled.
従って、その座席用の上半身用空気吹出口32から吹き
出す空気は、予め設定した通り、温度が変動する。Therefore, the temperature of the air blown from the upper body air outlet 32 for the seat fluctuates as set in advance.
吹出空気の温度が変動する上半身用空気吹出口32が複
数個あるときは、温度変動制御装置23は、冷気を最も必
要とする上半身用空気吹出口32に適するように冷気通路
20の流量調整弁21の開度を制御し、これに応じて各加熱
装置34の発熱量を制御する。When there are a plurality of upper body air outlets 32 in which the temperature of the blown air fluctuates, the temperature fluctuation control device 23 causes the cool air passage to be suitable for the upper body air outlets 32 that require cool air most.
The opening degree of the flow rate adjusting valve 21 of 20 is controlled, and the heat generation amount of each heating device 34 is controlled in accordance with this.
