Abstract (en)
[origin: EP3575711A1] A refrigeration cycle device (1) has a switching unit (13) disposed on a discharge side of a first compressor (11) to switch a flow of refrigerant discharged from the first compressor to a first passage (21) or a second passage (22). A first connector (25) is provided upstream of a condenser (14), and connects the first passage (21) and the second passage (22) with each other. A second compressor (12) is disposed on a middle of the second passage (22). A third passage (23) is branched at a branch unit (27) downstream of the condenser (14), and a second connector (26) connects a part of the second passage (22) on a suction side of the second compressor (12) and a part of the third passage downstream of an intermediate heat exchanger (16).
