Title:
VEHICLE AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/042699
Kind Code:
A1
Abstract:
In the present invention, a vehicle air conditioning device is provided with an air conditioning duct (10) that includes a first air passage (101) and a second air passage (102). A heater core (34) is disposed in the second air passage and heats air which was cooled by an evaporator (6). An auxiliary heat exchanger (4) includes a first heat exchange unit (4a) that performs heat exchange between a refrigerant and air that flows without passing through the heater core. In a case where an air-volume ratio adjusting device (17) operates so that the air-volume ratio of air flowing through the second air passage becomes greater, the air-volume ratio adjusting device enters into a first state in which the heater core is closed and air flows to the first heat exchange unit in the air flow within the air conditioning duct, and then enters into a second state in which air flows to the first heat exchange unit and the heater core. Due to this configuration, when heating the air which was cooled by the evaporator, the auxiliary heat exchanger can sufficiently provide heat exchanging capacity.
