PROBLEM TO BE SOLVED: To provide an air conditioner in which a heat exchanger can maintain optimal heat exchange efficiency in each case of a cooling operation and a heating operation.SOLUTION: An air conditioner includes an outdoor heat exchanger that is divided into a plurality of unit flow paths. At least two of the plurality of unit flow paths are connected in series or parallel to one another according to whether a cooling operation or a heating operation is performed, so that it is possible to vary the number or length of flow paths through which a refrigerant passes. Since the number or length of flow paths is properly selected and used, it is possible to enhance efficiency. |
