In an air-conditioning apparatus in which air sucked into a casing of an outdoor unit by a fan is discharged from an upper portion of the casing, each of liquid header portions is configured to be connected with each of heat transfer tubes of a plurality of divided regions formed by dividing the outdoor heat exchangers in an up and down direction. Further, a shunt is configured to supply two-phase refrigerant, in which quality is adjusted by a gas-liquid separator, to each of the liquid header portions. To each of the liquid header portions, the shunt supplies the two-phase refrigerant of the amount corresponding to the air quantity of the divided region connected to each of the liquid header portions. |

1. An air-conditioning apparatus comprising:
a refrigeration cycle including a compressor, a condenser, an expansion valve, an outdoor heat exchanger serving as an evaporator, and a liquid header connected to a position that is a refrigerant inflow side of the outdoor heat exchanger when the outdoor heat exchanger serves as the evaporator; an outdoor fan configured to supply air to the outdoor heat exchanger, the outdoor heat exchanger being provided to a casing of an outdoor unit such that heat transfer tubes are arranged in parallel in an up and down direction, the air, sucked into the casing of the outdoor unit by the outdoor fan, being discharged from an upper portion of the casing after exchanging heat in the outdoor heat exchanger, the liquid header being divided into a plurality of liquid header portions in the up and down direction, each of the liquid header portions being configured to be connected with each of the heat transfer tubes of divided regions formed by dividing the outdoor heat exchanger in the up and down direction, a first gas-liquid separator configured to separate two-phase refrigerant, flowing out of the expansion valve, into gas refrigerant and liquid refrigerant; a bypass connecting the first gas-liquid separator and a suction side of the compressor, the bypass being configured to adjust an amount of the gas refrigerant, separated by the first gas-liquid separator, to be returned to the suction side of the compressor; and a shunt connecting the first gas-liquid separator and each of the liquid header portions and configured to supply the two-phase refrigerant, in which quality is adjusted by the first gas-liquid separator, to each of the liquid header portions, the shunt being configured to supply, to each of the liquid header portions, the two-phase refrigerant of an amount corresponding to an air quantity of the divided region connected with each of the liquid header portions. |
