<p>An air conditioner includes an outdoor heat exchanger (10) that is divided into a plurality of unit paths (20,30), at least two of the plurality of unit paths are connected in series or parallel to one another according to cooling/heating operation, so that it is possible to vary the number or length of paths through which a refrigerant passes. Since the number or length of paths is properly selected and used, it is possible to enhance efficiency.</p> |
