The purpose of the present invention is to provide a refrigeration cycle device that does not cause capacity imbalance between branching units and does not cause refrigerant circuit control failure. At least one of a plurality of branching units (1a, 1b) is a first branching unit (1a) in which the pressure loss while refrigerant is flowing in high pressure refrigerant piping (2a) between a heating source (100) and the branching units (1a, 1b) is the minimum. At least one other of the plurality of branching units (1a, 1b) is a second branching unit (1b) in which the pressure loss while refrigerant is flowing in the high pressure refrigerant piping (2a) between the heating source (100) and the branching units (1a, 1b) is the maximum. The opening degree of a throttling device (8a) is controlled so that the pressure difference between the refrigerant pressure detected by a high pressure detector (PS1) [1a] in the first branching unit (1a) and the refrigerant pressure detected by an intermediate pressure detector (PS2) [1a] is no less than a default value (ΔPHM). |
