REFRIGERATION CYCLE DEVICE

摘要

A refrigeration cycle device (100) is comprised of a first compressor (101), a second compressor (102), a radiator (4), an evaporator (6), and a pipe branching portion (30). The first compressor (101) has a first compression mechanism (1) and an expansion mechanism (5). A second compressor (102) has a second compression mechanism (2). The pipe branching portion (30) constitutes passages through which a refrigerant is introduced from the evaporator (6) to the first compression mechanism (1) and the second compression mechanism (2). The pipe branching portion (30) is comprised of an inlet tube (31) for receiving the refrigerant from the evaporator (6); a first branched outlet tube (32) for introducing the refrigerant received by the inlet tube (3) to the first compression mechanism (1); and a second branched outlet tube (33) for introducing the refrigerant received by the inlet tube (3) to the second compression mechanism (2). The angle between the inlet tube (31) and the first branched outlet tube (32) is an obtuse angle or 180°, and the angle between the inlet tube (31) and the second branched outlet tube (33) is an acute angle.
