Abstract: An air conditioner including a compressor, an outdoor heat exchanger, an expansion valve, an indoor heat exchanger, a first fan, a second fan, and a cooling/heating conversion device. The compressor is configured to compress a refrigerant and including a first compressor and a second compressor. The outdoor heat exchanger is configured to exchange heat of the refrigerant with outdoor air, and includes a first and second heat exchanger. The expansion valve is configured to expand a refrigerant. The indoor heat exchanger is configured to exchange heat of the refrigerant with indoor air. The first fan and the second fan correspond to the first heat exchanger and the second heat exchanger, respectively. The cooling/heating conversion device during a during a heating operation is connected in parallel to the first and second heat exchangers, and during a during a cooling operation is connected in series to the first and second heat exchangers.

Abstract: A heat exchanger is provided. The heat exchanger comprises: a first header comprising a first globe and a second globe; a second header disposed in parallel with the first header; a tube assembly comprising multiple first tubes for connecting the first header and the second header and causing a refrigerant introduced from the first globe to flow in a first direction toward the position of the second header, and multiple second tubes disposed continuously with the multiple first tubes so as to cause a refrigerant introduced from the second header to flow in a second direction that is opposite to the first direction; and multiple heat exchange-fins individually having multiple insertion portions, into which the multiple first tubes and the multiple second tubes are inserted, respectively, and heat exchange surfaces disposed between the multiple insertion portions. The first heat-exchange fin, which is adjacent to the first header among the multiple heat exchange fins, has a heat-exchange surface including a first surface having a louver formed thereon, and a second surface formed to be flat and adjacent to insertion portions into which multiple second tubes are inserted. The second heat-exchange fin, which is adjacent to the second header, has a heat-exchange surface including a first surface.
