PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of saving electric power.SOLUTION: A refrigeration cycle device comprises; a first cooling space; a second cooling space lower in temperature than the first cooling temperature; a compressor 21; a condenser 22; a high temperature-side switching part 27 connected to the condenser 22; first and second expansion devices 23, 33 arranged in parallel with the high temperature-side switching part 27 interposed; a first evaporator 24 which cools the first cooling space; a second evaporator 34 which cools the second cooling space; and an ejector 26 which has an inflow port connected to the first evaporator 24, a suction port connected to the second evaporator 34, and an outflow port connected to the compressor 21. The refrigeration cycle device has: a first cooling mode in which a refrigeration is circulated to the first evaporator 24 and stopped from being circulated to the second evaporator 34 through switching of the high temperature-side switching part 27; a second cooling mode in which the refrigerant is circulated to the second evaporator 34 and stopped from being circulated to the first evaporator 24; and a simultaneous cooling mode in which the refrigerator is circulated to the first evaporator 24 and second evaporator 34.SELECTED DRAWING: Figure 2 |
