PROBLEM TO BE SOLVED: To provide an air conditioner of high performance by improving heat exchange performance of a heat exchanger.SOLUTION: In a refrigerant flow channel of a heat exchanger 12, a gas refrigerant in acting as a condenser, flows in from two gas-side inflow ports G1, G2 at positions separating from each other of a second row F2, and the refrigerant flow channel is constituted in a direction to close to each other while reciprocating between one end portion S1 and the other end portion S2. The refrigerant flow channels from two gas-side inflow ports G1, G2 are joined at one end portion S1, the refrigerant flow channel is connected to a heat transfer pipe 2 of a first row F1 from the second row F2, and the refrigerant flow channel is constituted within a range from a stage same as one gas-side inflow port G1 of the second row F2 to a stage same as the other gas-side inflow port G2 of the second row F while reciprocating between one end portion S1 and the other end portion S2 of the first row F1, and reaches a liquid-side outflow port L1.SELECTED DRAWING: Figure 3 |
