Abstract: Air conditioner for vehicle, small and having two independent air flow paths, controlling air volume independently for each air flow path, and can remove noise while regulating the air volume corresponding to the desired flow path through means for returning flowing air toward a suction port. The air conditioner for vehicle comprises a blower having a plurality of blower wheels, and one blower motor for driving the plurality of blower wheels with the same force, a plurality of inlet flow paths allowing an air inflow port to communicate with a blower inlet, and a return flow path which has a plurality of outlet flow paths allowing a blower outlet to communicate with an air discharge port, which returns, to the blower inlet, at least a part of the air discharged from the blower outlet so that the air volumes discharged from the plurality of air discharge ports are regulated differently.

Abstract: Disclosed is a heat exchanger capable of exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind from the first coolant flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.
