Abstract
In a refrigerant cycle device with an ejector, a branch portion is located at an upstream side of a nozzle portion of the ejector so that the refrigerant flowing out of an exterior heat exchanger is branched into first and second streams in a cooling operation mode. A passage switching portion is configured such that the refrigerant of the first stream flows through the nozzle portion of the ejector, and the refrigerant of the second stream flows through the decompression unit, the using-side heat exchanger, and the refrigerant suction port of the ejector, in the cooling operation mode. In contrast, the refrigerant discharged from the compressor flows into the nozzle portion after passing through the using-side heat exchanger, and the refrigerant flowing out of the exterior heat exchanger flows into the refrigerant suction port of the ejector, in the heating operation mode.
