<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device which can incorporate a refrigerant reservoir in a secondary refrigerant circuit while suppressing a pressure loss as much as possible. <P>SOLUTION: A refrigeration circuit 12 on a primary side supplies a first refrigerant compressed to be a high temperature and a high pressure by a compressor 14 to a first heat exchanger 18 or a second heat exchanger 21 between the compressor 14 and an expansion valve 19. A transportation circuit 13 on a secondary side circulates a second refrigerant, which exchanges thermal energy with the first refrigerant by means of the second heat exchanger 21, between the second heat exchanger 21 and a third heat exchanger 27. The pressure in the transportation circuit 13 is adjusted at a refrigerant tank 29. When the pressure of the second refrigerant drops down to a predetermined pressure in the transportation circuit 13 during cooling operation, the refrigerant reservoir 29 is separated from a circulation path 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
