Abstract:
1. A refrigeration cycle system having a compressor for sucking, compressing and discharging refrigerant, comprising: a flow rate sensor for detecting the flow rate of the refrigerant discharged from the compressor; an oil separator arranged on the upstream side of the flow rate sensor in the refrigerant flow to separate the lubricating oil from the refrigerant discharged from the compressor; and an oil introduction path for introducing the lubricating oil separated by the oil separator to the refrigerant inlet of the compressor, wherein the flow rate sensor includes a throttle portion for reducing the flow rate of the refrigerant discharged from the compressor, and a pressure difference detection mechanism for detecting the refrigerant pressure difference between the upstream side and the downstream side of the throttle portion in the refrigerant flow, wherein the compressor includes a housing having a refrigerant inlet and a refrigerant outlet and a compression unit accommodated in the housing to compress the refrigerant introduced thereinto through the refrigerant inlet and discharge the compressed refrigerant from the refrigerant outlet, and wherein the flow rate sensor is arranged between the compression unit and the refrigerant outlet in the housing.
