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.

摘要： To obtain a stacked heat exchanger in which the need to provide a step of bending heat exchanger pipes is eliminated and a space which cannot be utilized because of the provision of a header pipe is not produced, and also to obtain a heat pump system having the heat exchanger installed therein. A heat exchanger (10) is configured such that a plurality of rectangular first heat exchanger pipes (1) and a plurality of rectangular second heat exchanger pipes (2) are alternately stacked on each other. The first and second heat exchanger pipes (1 and 2) each have a refrigerant flow channel having a rectangular cross section through which a refrigerant flows. The first and second heat exchanger pipes (1 and 2) have substantially the same length in a direction in which refrigerants flow through the refrigerant flow channels and also have substantially the same width in the widthwise direction of the refrigerant flow channels.
