Document Type and Number:
Japanese Patent JP7098866
Kind Code:
B2
Abstract:
[Problem] To provide a vehicle air-conditioning apparatus that can easily cool a plurality of devices having different target cooling temperatures to the respective target cooling temperatures thereof. [Solution] The vehicle air-conditioning apparatus according to the present invention is provided with: a first heating medium circuit 30 through which a first heating medium that absorbs heat radiated from a battery B circulates; a second heating medium circuit 40 through which a second heating medium that absorbs heat radiated from an electric motor M circulates; a first heating medium heat exchanger 23a that performs heat exchange between a refrigerant circulating through a refrigerant circuit 20 and the first heating medium circulating through the first heating medium circuit 30 so that heat from the first heating medium is radiated to the refrigerant; a second heating medium heat exchanger 23b that is connected to the first heating medium heat exchanger 23a in series in the refrigerant circuit 20 and performs heat exchange between the refrigerant circulating through the refrigerant circuit 20 and the second heating medium circulating through the second heating medium circuit 40 so that heat from the second heating medium is radiated to the refrigerant; and a fourth expansion valve 24d capable of changing the opening area of a refrigerant circulation path 20g between the first heating medium heat exchanger 23a and the second heating medium heat exchanger 23b.
