Kind Code:
A1
Abstract:
A refrigeration cycle device (100) comprises a refrigerant circuit that includes a compressor (1), a four-way valve (2), a second flow-path-switching part (10), a first outdoor heat exchanger (3), a second outdoor heat exchanger (4), a first indoor heat exchanger (6a), and a second flow-path-switching part (10). Refrigerant is circulated through the refrigerant circuit. The second flow-path-switching part (10) has a first port (P1), a second port (P2), a third port (P3), a fourth port (P4), a fifth port (P5), and a sixth port (P6) through which refrigerant flows in and out. The second flow-path-switching part (10) switches between: a third state in which the first port (P1), the second port (P2), the first outdoor heat exchanger (3), the fourth port (P4), the third port (P3), the second outdoor heat exchanger (4), the fifth port (P5), and the sixth port (P6) are connected in series in the stated order; and a fourth state in which the sixth port (P6), the fourth port (P4), the first outdoor heat exchanger (3), the second port (P2), and the first port (P1) are connected in series in the stated order, and in which the sixth port (P6), the fifth port (P5), the second outdoor heat exchanger (4), the third port (P3), and the first port (P1) are connected in series in the stated order.
