Title:
VEHICLE AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/251110
Kind Code:
A1
Abstract:
A vehicle air conditioning system (1) is provided with: a plurality of air conditioners (10, 20) disposed respectively corresponding to a plurality of air conditioning zones; and a cooling machine (30) that cools a target device mounted to a vehicle. The plurality of air conditioners respectively include vapor compression-type refrigeration cycles (RC1, RC2) in order to cool air blowing out to the plurality of air conditioning zones through heat absorption action performed by evaporation of refrigerant. The cooling machine includes a cooling circuit (31) through which a heat medium for exchanging heat with the target device flows, and adjusts the temperature of the target device by cooling the heat medium using heat absorption action in at least a part of the plurality of air conditioners. Among the plurality of air conditioners, an air conditioner for performing air conditioning of a door-side zone is defined as a door-side air conditioner (10), and an air conditioner for performing air conditioning of a panel-side zone is defined as a panel-side air conditioner (20). Note that the amount of heat absorption from the heat medium during device temperature adjustment when the plurality of air conditioners perform indoor cooling and temperature adjustment of the target device, is less in the door-side air conditioner than that in the panel-side air conditioner.
