Title:

REFRIGERATING CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/140324

Kind Code:

A1

Abstract:

Provided is a refrigerating cycle device capable of volume flow matching without pre-expansion. The refrigerating cycle device comprises: a refrigerating cycle circuit (30) in which a compression unit (a main compressor (5) and a secondary compressor (23)), a gas cooler (11), an expansion mechanism (2), and an evaporator (12) are connected by piping; and a sub-compression mechanism (3) driven by the power recovered by the expansion mechanism (2). The inlet and outlet sides of the sub-compression mechanism (3) are connected to the compression process in the compression unit and the entrance side of the gas cooler (11), respectively, thereby controlling the flow rate of a refrigerant flowing into the sub-compression mechanism (3).
