A refrigeration cycle device (1000) includes a refrigerant circuit in which a refrigerant circulates, the refrigerant circuit being provided with a compressor (1), a flow path switching unit (2), an outdoor heat exchanger (3), decompression devices (4A, 4B), a first indoor heat exchanger (5A), a first connection pipe (10), and a second connection pipe (11). The refrigerant circuit further includes a first three-way valve (8A) disposed downstream of the first indoor heat exchanger in the cooling operation state and upstream of the first indoor heat exchanger in the heating operation state, and a second three-way valve (9A) disposed upstream of the first indoor heat exchanger in the cooling operation state and upstream of the second indoor heat exchanger in the heating operation state. The second indoor heat exchanger is disposed downstream of the first indoor heat exchanger in a heating operation state. A first opening (P1) of each of the first three-way valve and the second three-way valve is connected to one
