- 전기자동차용 공조장치의 초기화상태에서 각종 입력수단(90)으로부터 입력되는 신호를 제어유니트(80)가 읽어들여 연산하는 단계와;상기 제어유니트의 출력신호에 따라 인버터(14)에 의해 압축기(10)를 구동하는 구동모터(12)에 구동전압이 인가됨으로써 설정 회전수로 압축기가 구동되어 통상적인 공조제어가 수행되는 단계와;상기 제어유니트에 의해 송풍기(60)의 실제구동전압(Vb)과 송풍기의 소음제한구동전압(Vc)의 크기를 판단하는 단계와;상기 송풍기의 실제구동전압이 송풍기의 소음제한구동전압보다 낮은 경우 제어유니트의 출력신호에 따라 인버터에 의해 압축기를 구동하도록 제어되는 구동모터에 보상구동전압이 인가됨으로써 압축기 회전수가 보상치만큼 낮은 회전수로 보상되는 단계와;상기 송풍기의 실제구동전압이 송풍기의 소음제한구동전압보다 낮은 경우 전기자동차용 공조장치의 실내측 열교환기를 거친 조화공기가 전기자동차 실내로 유동하는 공기유로의 개도를 조절하는 온도조절도어(70)를 제어유니트의 출력신호에 따라 상기 개도가 증가되도록 보상제어하는 단계;를 포함하는 것을 특징으로 하는 전기자동차용 압축기의 소음저감방법.
