Abstract: A refrigeration cycle device includes a compressor, a first branch portion, a radiator, a second branch portion, a first decompressor, a first evaporator, a second decompressor, a second evaporator, and an ejector. The first branch portion divides a flow of a refrigerant discharged from the compressor into one flow and an other flow. The radiator radiates heat of the refrigerant of the one flow. The second branch portion divides a flow of the refrigerant from the radiator into one flow and an other flow. The first decompressor decompresses the refrigerant of the one flow divided in the second branch portion. The second decompressor decompresses the refrigerant of the other flow divided in the second branch portion. A nozzle of the ejector decompresses and injects the refrigerant of the other flow divided in the first branch portion. The refrigerant suction port draws the refrigerant from the second evaporator.

Abstract: In a seat air-conditioning device, a refrigeration cycle, a warm air blower, and a cold air blower are housed in a housing disposed between a seat face of a seat and a vehicle interior floor. A condenser is disposed on an upstream side in an air blowing direction and the warm air blower is disposed on a downstream side in an air blowing direction in a warm air flow path extending in a predetermined direction. An evaporator is disposed on a downstream side of the cold air blower in an air blowing direction in the cold air flow path extending in a predetermined direction.
