Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/058849
Kind Code:
A1
Abstract:
[Problem] To provide a compressor with which it is possible to increase the capacity to separate oil from ejected refrigerant in the entire operation range of the compressor, to increase the OCR in the compressor, durability and performance of the compressor, and to achieve an increase in the operation efficiency of a system in which the compressor is used.
[Solution] The compressor 1 is provided with: a suction chamber 3 for suctioning a refrigerant which contains oil; a compression chamber 4 for compressing the refrigerant suctioned into the suction chamber 3; a refrigerant flow path 94 formed to externally discharge ejected refrigerant ejected from the compression chamber 4; first and second oil separators 90, 91 which are arranged in series in the refrigerant flow path 94, and which separate the oil contained in the ejected refrigerant using different oil separating capacities; a first oil flow path 92 for distributing the oil separated in the first oil separator 90 to a refrigerant suction side of the compression chamber 4; and a second oil flow path 93 for distributing the oil separated in the second oil separator 91 to the suction chamber 3 side.
