Abstract (en)
A refrigeration cycle apparatus includes a heat source unit (301), a plurality of indoor units (303a, 303b), and a branch unit (302) configured to transfer refrigerant. The branch unit (302) includes a plurality of six-way valves (10a, 10b) each being provided for a corresponding one of the plurality of indoor units (303a, 303b). Each of the six-way valves includes a housing (41) having a first port to a sixth port, and a valve body (42) disposed inside the housing and provided with a first flow path and a second flow path. In a second switching state, the first port communicates with the second port through the first flow path, and the fourth port communicates with the fifth port through the second flow path. In a first switching state, the second port communicates with the third port through the first flow path, and the fifth port communicates with the sixth port through the second flow path.
