摘要: An outdoor unit includes at least a compressor, a gas-liquid separator, and an outdoor heat exchanger of a refrigerant circuit, the refrigerant circuit being formed by connecting, by pipes, the compressor, a condenser, a pressure reducing device, the gas-liquid separator, and the outdoor heat exchanger that acts as an evaporator including at least a plurality of heat transfer tubes and an inlet header that distributes incoming refrigerant to the heat transfer tubes. The outdoor unit further includes a gas-liquid-separator bypass pipe, a gas-liquid-separator-side flow control valve, a header bypass pipe, a header-side flow control valve, and a determination device.

摘要: 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.

摘要: A refrigerant circuit includes: plural gas/liquid separators adapted to separate a two-phase gas-liquid refrigerant into refrigerant vapor and refrigerant liquid; a channel switching valve connected upstream of the gas/liquid separators and adapted to switch channels for the two-phase gas-liquid refrigerant by opening and closing; an evaporating heat exchanger adapted to accept inflow of the refrigerant liquid or the two-phase gas-liquid refrigerant, the refrigerant liquid produced by separation by the gas/liquid separators; a header installed upstream of the evaporating heat exchanger perpendicularly or at angles to the evaporating heat exchanger; a compressor installed downstream of the evaporating heat exchanger; and plural bypass routes connected to the respective gas/liquid separators and adapted to allow passage of the refrigerant vapor. The refrigerant vapor passing through the plural bypass routes and refrigerant vapor passing through the evaporating heat exchanger merge at a first meeting point between the evaporating heat exchanger and the compressor.
