Title:
VEHICLE AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/251109
Kind Code:
A1
Abstract:
A vehicle air-conditioning system (1) comprises a plurality of air conditioners (10) provided corresponding to respective air-conditioning zones, and a cooler (30) that cools a target device (BT) installed in the vehicle. Each of the plurality of air conditioners includes a vapor-compression refrigeration cycle, and the air blown out to the plurality of air-conditioning zones is cooled by the heat absorption effect resulting from the evaporation of a refrigerant. The air conditioners include a cooling circuit (31) through which flows a heat medium that exchanges heat with the target device, and the temperature of the target device is regulated due to the heat medium being cooled using the heat absorption effect in at least some of the plurality of air conditioners. Among the plurality of air conditioners, that which conditions the air in a door-side zone is a door-side air conditioner (10), and that which conditions the air in a panel-side zone is a panel-side air conditioner (20). At this time, the amount of heat absorbed from the heat medium during device temperature regulation, in which the air in the passenger cabin is cooled and the temperature of the target device is regulated by the plurality of air conditioners, is less in the panel-side air conditioner than in the door-side air conditioner.
