PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of preventing deterioration of cooling capacity.SOLUTION: A refrigeration cycle device includes: a compressor 21 for operating a refrigeration cycle 30; a condenser 22 for condensing a refrigerant compressed in the compressor 21; a branch part 27 for switching a flow passage of the refrigerant after flowing out of the condenser 22; a first expansion device 23 and a second expansion device 33 arranged in parallel via the branch part 27 and for expanding the refrigerant; a first evaporator 24 for evaporating the refrigerant by being connected to the first expansion device 23; a second evaporator 34 for evaporating the refrigerant by being connected to the second expansion device 33; an ejector 26 having an inlet port connected to the first evaporator 24, a suction port which is connected to the second evaporator 34 and in which the refrigerant is sucked by the inflow of the refrigerant from the inlet port, and an outflow port connected to the compressor 21; and a heater 40 for heating a refrigerant pipe for connecting the first evaporator 24 and the inflow port. The heater 40 is driven at the stop time of the compressor 21.SELECTED DRAWING: Figure 2 |
