<p>The present invention relates to an air conditioner which can inject refrigerant into a compressor during both a room heating operation and a room cooling operation. According to an embodiment of the present invention, the air conditioner includes: a compressor compressing the refrigerant; an outdoor heat exchanger installed outdoors and exchanging heat between outdoor air and the refrigerant; an indoor heat exchanger installed indoors and exchanging heat between indoor air and the refrigerant; a switching part guiding the refrigerant discharged from the compressor to the outdoor heat exchanger during a room cooling operation and to the indoor heat exchanger during a room heating operation; a first injection module injecting a portion of the refrigerant, flowing from the indoor heat exchanger into the outdoor heat exchanger, into the compressor during the room heating operation and supercooling the refrigerant flowing from the outdoor heat exchange into the indoor heat exchange during the room cooling operation; and a second injection module injecting a portion of the refrigerant, flowing from the indoor heat exchanger into the outdoor heat exchanger, into the compressor during the room heating operation and injecting a portion of the refrigerant, flowing from the outdoor heat exchanger into the indoor heat exchanger, into the compressor during the room cooling operation.</p> |
