Beschreibung
Zusammenfassung:	A vehicle air-conditioning apparatus according to the present invention includes an air-conditioning refrigerant circuit that circulates a refrigerant to cool an inside of a vehicle, a branching refrigerant circuit that branches from the air-conditioning refrigerant circuit and cools a heat generating device, a branching control valve that is provided in the branching refrigerant circuit and controls a flow of the refrigerant flowing into the branching refrigerant circuit from the air-conditioning refrigerant circuit, and a control unit that controls an operation of the air-conditioning refrigerant circuit and the branching control valve. After transition to an operation of cooling the inside of the vehicle by the air-conditioning refrigerant circuit and cooling the heat generating device by the branching refrigerant circuit in parallel, the control unit opens and closes the branching control valve in accordance with a cooling capacity state of the air-conditioning refrigerant circuit.
