VEHICULAR AIR CONDITIONING DEVICE

WIPO Patent Application WO/2023/203943

A1

When performing temperature adjustment of blown air at both of a plurality of air conditioning units including an HVAC unit, the present invention makes it possible to improve the air conditioning ability of the HVAC unit and perform air conditioning in a desired temperature zone at each of the plurality of air conditioning units while suppressing device cost.　Provided is a vehicular air conditioning device 1 comprising: a refrigerant circuit R; a heat transfer medium circuit 10 through which a heat transfer medium heated or cooled by the refrigerant circuit circulates; a first air conditioning unit that blows air, which has passed through some or all of a plurality of heat exchangers 81, 82 through which the heat transfer medium in the heat transfer medium circuit flows, into a vehicle interior; and a second air conditioning unit that blows air, which has passed through a heat exchanger 91, 92 through which the heat transfer medium in the heat transfer medium circuit flows, into part of the vehicle interior, wherein the heat transfer medium circuit comprises a confluence path in which one of the plurality of heat exchangers in the first air conditioning unit and the heat exchanger in the second air conditioning unit act as parallel flow paths and in which the heat transfer medium flowing through the heat exchangers of the parallel flow paths converges to flow through the other one of the plurality of heat exchangers of the first air conditioning unit.
