본 발명은 차량용 공조장치에 관한 것으로서, 공조소음을 저감시키는 소음저감장치를 제어하되, 블로어의 공기토출풍량과 공기토출모드 상태를 모두 고려하여 제어함으로써, 블로어의 공기토출풍량과 공기토출모드 상태에 따라 변화되는 공조소음에 효과적으로 대응할 수 있고, 이를 통해, 블로어의 공기토출풍량과 공기토출모드에 관계없이 차실내로 유입되는 공조소음을 효율좋게 저감시킬 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 공조 소음을 저감시킬 수 있는 소음저감장치를 포함하며, 소음저감장치는 공조 소음을 획득할 수 있는 소음 마이크와, 소음 마이크에서 획득한 공조 소음을 근거로 소음저감음파를 출력하여 공조 소음을 저감시키는 스피커를 포함하는 차량용 공조장치에 있어서, 공조케이스의 내부유로를 따라 유동하는 공기유동정보를 감지할 수 있는 공기유동정보 감지부와; 공기유동정보 감지부의 공기유동정보와, 소음 마이크에서 획득한 공조 소음을 감안하여 스피커를 제어하는 제어부를 구비한다.

    The present invention relates to an air conditioning device for a vehicle, wherein a noise reduction device which reduces air conditioning noise is controlled while considering all of the air discharge volume and the air discharge mode state of a blower, thereby effectively dealing with the air conditioning noise which is changed corresponding to the air discharge volume and the air discharge mode state of the blower. Resultantly, the air conditioning noise which is infiltrated into a vehicle compartment can be efficiently reduced regardless of the air discharge volume and the air discharge mode of the blower. To this end, the present invention comprises a noise reduction device which can reduce air conditioning noise. Here, the noise reduction device comprises: a noise microphone which can acquire air conditioning noise; and a speaker which reduces the air conditioning noise by outputting a noise reduction sound wave based on the air conditioning noise acquired by the noise microphone. In addition, the air conditioning device for a vehicle further comprises: an air flow information detection unit which can detect information of an air flow moving along an inner flow path of an air conditioning case; and a control unit which controls the speaker considering the air flow information of the air flow information detection unit and the air conditioning noise acquired by the noise microphone.
