본 발명은 차량용 공조장치에 관한 것으로서, 소음저감장치의 마이크 설치위치를 개선함으로써, 공조 소음의 획득효율을 높일 수 있고, 이를 통해, 소음저감장치의 공조 소음 감쇄성능을 개선시킬 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 공조 소음을 저감시킬 수 있는 소음저감장치를 포함하며, 소음저감장치는 공조케이스의 내부유로측 공조 소음을 획득할 수 있는 마이크와, 마이크에서 획득한 공조 소음을 근거로 공조케이스의 내부유로에 소음 감쇄 음파를 출력하여 공조소음을 저감시키는 스피커를 포함하는 차량용 공조장치에 있어서, 마이크는, 공조케이스의 내부유로 중, 블로어의 공기흡입구와, 공기흡입구의 상류측에 설치되는 에어필터 사이부분에 설치되어, 블로어측의 흡기소음을 획득한다.

    The present invention relates to an air conditioning apparatus for a vehicle, which is able to improve a microphone installation position of a noise reduction apparatus to increase the acquisition efficiency of air conditioning noise, and to improve the air conditioning noise reduction performance of the noise reduction apparatus. To this end, according to the present invention, the air conditioning apparatus for a vehicle comprises a noise reduction apparatus which is able to reduce air conditioning noise. The noise reduction apparatus includes: a microphone which is able to acquire air conditioning noise on an internal flow path side of an air conditioning case; and a speaker which outputs a noise reduction sound wave to an internal flow path of the air conditioning case based on the air conditioning noise acquired by the microphone, and reduces the air conditioning noise. The microphone is installed between an air inlet of a blower and an air filter which is installed on an upstream side of the air inlet in the internal flow path of the air conditioning case to acquire an air intake noise on the blower side.
