Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/091722
Kind Code:
A1
Abstract:
This refrigeration cycle device is provided with a refrigerant circuit through which a refrigerant circulates, the refrigeration cycle device comprising: a compressor that discharges a gas-phase refrigerant, a heat-source-side heat exchanger; a first expansion valve; a use-side heat exchanger; and an injection channel through which a portion of a liquid-phase refrigerant is distributed and injected into the compressor. In the injection channel, an electromagnetic valve, a check valve, and a second expansion valve are disposed, in that order from the upstream side of the flowing direction of the liquid-phase refrigerant in the injection channel. The second expansion valve enters a stopped state without being fully closed and having an aperture larger than the full closure.
