<P>PROBLEM TO BE SOLVED: To provide an air conditioner having a dehumidification valve in the middle of piping of an indoor heat exchanger, reducing refrigerant pressure loss within piping of an outdoor heat exchanger, improving outdoor heat exchange performance during heating operation and having high energy efficiency. Ž<P>SOLUTION: A gas-liquid separator 9 is provided in the middle of the refrigerant piping of the outdoor heat exchanger 6, and a bypass pipe 12 is provided to make separated gas refrigerant merge to outlet piping 10 of the outdoor heat exchanger 6 via a flow rate control valve 11. By performing control to adjust the opening of the flow rate control valve 11 in accordance with the rotational frequency of a compressor 1, pressure loss of a refrigerant made to flow within the outdoor heat exchanger 6 is reduced, so as to improve heating performance.
