Abstract
The refrigeration cycle device includes a compressor, an outside heat exchanger, a cooling pressure reducing unit, an evaporator, a branch portion, a cool down pressure reducing unit, a temperature adjusting unit, a merging portion, a bypass passage, and a first on-off valve. The temperature adjusting unit includes a temperature adjusting heat exchange unit and adjusts a temperature of a temperature adjustment target object. During a cooling and cool down mode, the outside heat exchanger functions as a radiator, and the evaporator and the temperature adjusting heat exchange unit function as heat absorbers. During a target object warm up mode, the refrigerant discharged from the compressor is guided to the temperature adjusting heat exchange unit via the bypass passage, and the heat of the discharged refrigerant is used as a heat source for heating the temperature adjustment target object.
