Refrigeration cycle device

A refrigeration cycle device comprising:

• a compressor configured to suck, compress, and discharge a refrigerant;
• a heat radiating unit configured to cause the refrigerant discharged from the compressor to radiate heat to heat air supplied to a space inside a vehicle cabin;
• a decompression unit configured to decompress the refrigerant having radiated heat in the heat radiating unit;
• an outside air heat absorbing unit configured to cause the refrigerant decompressed by the decompression unit to absorb heat from outside air;
• a waste heat absorbing unit configured to cause the refrigerant decompressed by the decompression unit to absorb waste heat of a waste heat device;
• a shutter configured to open and close to regulate an opening of a passage for the outside air introduced into the outside air heat absorbing unit;
• and
• a controller configured to close the shutter when the controller determines that an amount of waste heat of the waste heat device is larger than an amount of heat absorbed by the refrigerant in the outside air heat absorbing unit and the waste heat absorbing unit.
