Beschreibung
Zusammenfassung:	According to one embodiment of the present invention, an air conditioner comprises: a compressor compressing a refrigerant; an oil separator separating oil from the refrigerant discharged from the compressor; an oil recovery pipe connected between the oil separator and the compressor; and a control unit determining whether to perform oil recovery operation based on a driving frequency of the compressor and a Q-axis current. Therefore, the present invention can effectively recover the oil. 본 발명의 일 실시 예에 따른 공기조화기는, 냉매를 압축하는 압축기, 상기 압축기에서 토출된 냉매에서 오일을 분리하는 오일 분리기, 상기 오일 분리기와 상기 압축기 사이에 연결되는 오일 회수관, 상기 압축기의 운전 주파수 및 상기 압축기의 Q축 전류에 기초하여, 오일 회수 운전 여부를 결정하는 제어부를 포함함으로써. 오일을 효과적으로 회수할 수 있다.
