A refrigeration cycle device that is capable of operating with high efficiency in both a heating operation and a cooling operation and that is reliable is provided. In a heating operation, a switching device performs switching of a flow path of a refrigerant in such a manner that a refrigerant that has been compressed by a compressor flows into a refrigerant inlet port of an ejector via a third heat exchanger and is suctioned by a refrigerant suction port of the ejector via a first heat exchanger, a controller, and a second heat exchanger in this order, and in such a manner that a refrigerant that is discharged from a refrigerant outlet port of the ejector is suctioned by the compressor via a fourth heat exchanger. In a cooling operation, the switching device performs switching of a flow path of a refrigerant in such a manner that a refrigerant that has been compressed by the compressor flows into the refrigerant inlet port of the ejector via the fourth heat exchanger and is suctioned by the refrigerant suction port of the ejector via the second heat exchanger, the controller, and the first heat exchanger in this order, and in such a manner that a refrigerant that is discharged from the refrigerant outlet port of the ejector is suctioned by the compressor via the third heat exchanger. |
