Title:
REFRIGERATING CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2010169337
Kind Code:
A
Abstract:

To enhance the reliability of a refrigerating cycle device by providing a first compressor and a second compressor having different structures.

The refrigerating cycle device 100 includes the first compressor 101, the second compressor 102, a radiator 4, an evaporator 6 and a high pressure refrigerant route 50. The first compressor 101 includes a first compression mechanism 1 and an expansion mechanism 5, and the first compression mechanism 1 and the expansion mechanism 5 are connected by a shaft 23. A second compression mechanism 2 of the second compressor 102 is arranged in a refrigerant circuit in parallel with the first compression mechanism 1. The high pressure refrigerant route 50 includes a common route 52 and a communication route 54. A refrigerant compressed by the second compression mechanism 2 is guided to an inner space of a first closed container 10 via the communication route 54 and merged with a refrigerant compressed by the first compression mechanism 1. The merged refrigerants are made to flow in the common route 52, and guided to the radiator 4.
