Kind Code:
A1
Abstract:
[Problem] To provide a vehicle air conditioning unit capable of improving comfort while being able to quickly reach a target temperature inside a vehicle compartment. [Solution] A vehicle air conditioning unit (20) is such that an auxiliary adjustment unit (65), which is capable of adjusting the flow rate of blown air by modulating the flow channel area of a lower cool air bypass (By2), is formed on a rotational shaft part (61) of a lower mix door (60). When both the blown air that has passed through a lower part of heater (33) and the blown air that has passed through the lower cool air bypass (By2) flow toward a rear opening (44), the auxiliary adjustment unit (65) narrows the flow channel cross-sectional area of the lower cool air bypass (By2) and sets the flow rate of the blown air flowing to the lower cool air bypass (By2) to be at a maximum during a full cooling mode in which the amount of blown air passing through the heater (33) is at a minimum.
