摘要： A heat exchanger (10) includes a first flat pipe (1) having a plurality of through-holes through which a high-temperature fluid flows, a second flat pipe (2) having a plurality of through-holes (21) through which a low-temperature fluid flows, a first inlet header (3) having a tubular shape and connected to one end of the first flat pipe (1), a first outlet header (4) having a tubular shape and connected to other end of the first flat pipe (1), a second inlet header (5) having a tubular shape and connected to one end of the second flat pipe (2), and a second outlet header (6) having a tubular shape and connected to other end of the second flat pipe (2). The first flat pipe (1) and the second flat pipe (2) are stacked such that flat surfaces thereof are in contact with each other. The low-temperature fluid flowing into the through-holes (21) in the second flat pipe (2) from the second inlet header (5) is a fluid in a two-phase gas-liquid state. The low-temperature fluid flows into the through-holes (21) in the second flat pipe (2) from the second inlet header (5) in a substantially horizontal direction or in an upward direction relative to the substantially horizontal direction.

摘要： An outdoor unit according to the present invention comprises 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 comprises a gas-liquid-separator bypass pipe that causes refrigerant in gaseous form separated by the gas-liquid separator to bypass the evaporator, a gas-liquid-separator-side flow control valve that controls a flow rate of the refrigerant through the gas-liquid-separator bypass pipe, a header bypass pipe having one end connected to the inlet header at the header termination side located opposite to the refrigerant inlet side of the inlet header, the header bypass pipe sucking the refrigerant entering the inlet header, a header-side flow control valve that controls the flow rate of the refrigerant through the header bypass pipe, and a determination device that determines, from the frequency of the compressor, the opening degrees of the gas-liquid-separator-side flow control valve and the header-side flow control valve.
