Abstract (en)
[origin: EP4261475A1] An injection circuit (60) includes a gas-liquid separator (7) to separate some of refrigerant into gas and liquid, a first pipe (8) through which liquid refrigerant is discharged from the gas-liquid separator (7), a second pipe (9) through which gas refrigerant is discharged from the gas-liquid separator (7), a third pipe (10) in which refrigerant that flows through the first pipe (8) and refrigerant that flows through the second pipe (9) merge with each other to flow to an injection port (1p) of a compressor (1), a flow rate regulation valve (13) provided in the first pipe (8), and a solenoid valve (14) provided in the second pipe (9). A refrigeration cycle apparatus (100) includes a control device (70) to adjust an amount of refrigerant in a main circuit (50) by controlling an opening of the flow rate regulation valve (13) and an open and closed state of the solenoid valve (14).
