A refrigeration cycle device comprises a compressor (11), a radiator (12, 121), an ejector (13, 20), a gas-liquid separating device (30f, 21), an evaporator (14), and a high-pressure refrigerant hose (15). The compressor compresses and discharges a refrigerant in which a refrigeration oil is mixed. The radiator dissipates heat from the high-pressure refrigerant discharged from the compressor. The ejector has a nozzle (32, 20a) and a body (30, 20b). The high-pressure refrigerant hose couples the discharge opening of the compressor to the refrigerant inlet of the radiator. The high-pressure refrigerant hose is formed as a multiple layered structure. The high-pressure refrigerant hose has a first layer formed from rubber and a second layer formed from a resin that inhibits the permeation of refrigerant. The refrigerant is a hydrofluoroolefin-based refrigerant, and the refrigeration oil has an OH group. By virtue of the refrigeration cycle device, deterioration of the high-pressure refrigerant hose can be suppressed and refrigerant leaks from the high-pressure refrigerant hose can be suppressed. |
