An air conditioning device comprising: a compressor (10) that compresses and discharges refrigerant; a heat source-side heat exchanger (12) that exchanges heat with the refrigerant; a supercooling heat exchanger (13) having a first flow path and a second flow path, causing heat to be exchanged with refrigerant that passes through each flow path, and supercooling a refrigerant flowing through the first flow path; a throttle device (16) that decompresses the refrigerant; a usage-side heat exchanger (17) that exchanges heat with the refrigerant; first bypass pipes (4a) connected to the intake side of the compressor (10), configuring a refrigerant circuit connected by pipes to an accumulator (15) that stores residual refrigerant, said refrigerant circuit causing refrigerant to be circulated and said first bypass pipes connecting the second flow path in the supercooling heat exchanger (13) and pipes for the refrigerant inlet side of the accumulator (15); a throttle device (14a) that adjusts the flow rate of refrigerant that flows through the first bypass pipes (4a); second bypass pipes (4b) that connect pipes between the heat source-side heat exchanger (12) and the usage-side heat exchanger (17) to pipes between the refrigerant outflow side of the accumulator (15) and the intake side of the compressor (10); and a throttle device (14b) that adjusts the flow rate of refrigerant that flows through the second bypass pipes (4b).
