| 摘要 |
According to the present invention, a heat pump cycle (10) comprises a compressor (11), a radiator (12), a first pressure reducing mechanism (13), a gas-liquid separator (14), an intermediate pressure refrigerant passage (15), a second pressure reducing mechanism (19), an outdoor heat exchanger (20) and an accumulator (30). The accumulator (30) has an interior heat exchange unit (32) that heat exchanges refrigerant in the interior and liquid-phase refrigerant that flows through a liquid-phase refrigerant passage from a liquid phase refrigerant flow outlet side of the gas-liquid separator (14) to the refrigerant inlet side of the second pressure reducing mechanism (19) and that heats refrigerant in the interior of the accumulator (30). |
