The refrigeration cycle device includes: a heat medium circuit through which a heat medium circulates; power train equipment which is electrical equipment for generating a vehicle driving force and is cooled by the heat medium; a radiator which exchanges heat between the heat medium and outside air; a chiller which exchanges heat between a refrigerant of a refrigeration cycle and the heat medium; a circuit switching unit which switches the heat medium circuit between a first circulation state in which the heat medium circulates between the power train equipment and the radiator and a second circulation state in which the heat medium circulates between the power train equipment and the chiller; and a control unit which controls a heat balance of the power train equipment such that in the second circulation state, a temperature related to a temperature of the power train equipment does not exceed an upper limit temperature.
