Document Type and Number:
Japanese Patent JP2018177083
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular air conditioner capable of improving operation efficiency when cooling a battery by cooling a heating medium of a battery temperature adjustment device by a coolant of a coolant circuit.SOLUTION: A vehicular air conditioner includes: a battery temperature adjustment device 61 for cooling a battery 55 by circulating a heating medium in the battery; a coolant-heating medium heat exchanger 64 for heat-exchanging at least a part of the coolant discharged from an outdoor heat exchanger 7 with the heating medium circulating in the battery temperature adjustment device; and an auxiliary expansion valve 73 for reducing pressure of the coolant flowing in the coolant-heating medium heat exchanger. A control device controls a compressor 2 or the auxiliary expansion valve on the basis of a temperature Tw of the coolant in the coolant-heating medium heat exchanger so as to adjust a battery temperature Tb to a target battery temperature TBO.SELECTED DRAWING: Figure 1
