A vehicle air-conditioning device comprises: a first circuit (18) through which a refrigerant circulates; a heater (17) that heats the refrigerant circulating through the first circuit; a first pump (20) that is provided in the first circuit (18) for the circulation of the refrigerant; a second circuit (23) for cooling a heat generation unit (12); a second pump (27) that is provided in the second circuit for the circulation of the refrigerant; an adjustment unit (21) that adjusts the amount of the refrigerant circulating through the first circuit and the amount of the refrigerant circulating through the second circuit; and a control unit (16). The vehicle is equipped with a regenerative device (14), and an electricity storage device (13) is charged with electric energy recovered by the regenerative device. In the case where the electric energy is recovered by the regenerative device and it is necessary to consume power of the electricity storage device, the control unit heats the refrigerant by driving the heater and converts the power of the electricity storage device into heat energy. Thus, it is possible to drive the heater in accordance with the temperature of the refrigerant and the amount of heat required for air conditioning, and to use the energy recovered by the regenerative device not only for charging the electricity storage device, but also for vehicle interior air conditioning, thereby reducing the possibility of having to release the regenerative device and enabling efficient use of the energy recovered by the regenerative device. |
