Title:
COMPRESSOR AND HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2019167893
Kind Code:
A
Abstract:
To provide a compressor and a heat pump system, which can switch an injection state according to an operating condition with a simple configuration.SOLUTION: A compressor comprises at least a suction part, a compression part, and a discharge part, and comprises an injection port (10i) and an injection switching mechanism part (70). The injection switching mechanism part comprises a path that leads a liquid-phase refrigerant introduced via the injection port to an intermediate pressure part of the compressor, a heating chamber (70h) configured to heat the liquid-phase refrigerant flowing therein, and a refrigerant path switching mechanism (76, 76S). When the refrigerant path switching mechanism is in a first position, the liquid-phase refrigerant is led to the intermediate pressure part 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 is led to the intermediate pressure part of the compressor as a vapor-phase refrigerant.SELECTED DRAWING: Figure 2
