PROBLEM TO BE SOLVED: To provide a refrigeration cycle device that can suppress a decline in heating capacity of heating target fluid in a radiator even if a temperature of heat absorption target fluid is lowered.SOLUTION: A refrigeration cycle device includes an ejector 21 for sucking a refrigerant on the downstream side of an outdoor heat exchanger 15 functioning as an evaporator from a refrigerant suction port 21d through suction of an injected refrigerant that is injected from a nozzle portion 21a for decompressing part of a refrigerant discharged from the compressor 11 and for increasing the pressure of a refrigerant mixture of the injected refrigerant and the sucked refrigerant at a diffuser portion 21f. The refrigerant flowing out from the diffuser portion 21f is sucked to the compressor 11. Due to this configuration, the density of the sucked refrigerant to the compressor 11 is increased, so as to inhibit a decline in a flow rate of the refrigerant flowing in to an indoor condenser 12 that serves as a radiator. Thus, even if a temperature of outside air (heat absorption target fluid) is lowered, a decline in heating capacity of blowing air (heating target fluid) in the indoor condenser 12 can be suppressed. |
