Title:
COMPRESSOR AND HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/181244
Kind Code:
A1
Abstract:
Provided are a compressor and a heat pump system capable of switching an injection state in response to an operating condition with a simple configuration. The compressor is provided with at least a suction unit, a compression unit, and an ejection unit, and is further provided with an injection port (10i) and an injection switching mechanism unit (70). The injection switching mechanism unit is provided with a path that guides a liquid-phase refrigerant introduced via the injection port to an intermediate compression unit of the compressor, a heating chamber (70h) configured to heat the liquid-phase refrigerant that has flowed in, and a refrigerant path switching mechanism (76, 76S). When the refrigerant path switching mechanism is in a first position, the liquid-phase refrigerant is guided to the intermediate compression unit of the compressor without passing through the heating chamber. When the refrigerant path switching mechanism is in a second position, the liquid-phase refrigerant is vaporized through the heating chamber and guided to the intermediate compression unit of the compressor as a vapor-phase refrigerant.
