Document Type and Number:
Japanese Patent JP4837150
Kind Code:
B2
Abstract:
A refrigeration cycle apparatus which is capable of performing matching of the volumetric flow rate without performing pre-expansion is disclosed. As described above, a refrigeration circuit (30) including a compression unit (a main compressor (5) and a second compressor (23)), a gas cooler (11), an expansion mechanism (2), and an evaporator (12) interconnected with pipes, and a sub-compression mechanism (3) driven by power recovered by the expansion mechanism (2) are provided, a suction side of the sub-compression mechanism (3) is connected to a compression process of the compression unit, a discharge side of the sub-compression mechanism (3) is connected to an inlet side of the gas cooler (11), and flow rate of refrigerant flowing into the sub-compression mechanism (3) is controlled.
