Title:
AIR CONDITIONER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/064944
Kind Code:
A1
Abstract:
The present invention addresses the problem of eliminating the discomfort of an occupant caused by a decrease in cooling capability when transitioning to a driving mode in which heat exchange routes of a refrigerant increase, in an air conditioner for a vehicle. This air conditioner for a vehicle comprises: an air conditioning refrigerant circuit which circulates a refrigerant to cool the inside of a vehicle compartment; a branch refrigerant circuit which branches from the air conditioning refrigerant circuit and cools a heat generating apparatus; a branch control valve which is provided to the branch refrigerant circuit and controls the flow of the refrigerant entering the branch refrigerant circuit from the air conditioning refrigerant circuit; and a control unit which controls the operation of the air conditioning refrigerant circuit and the branch control valve, wherein the control unit, after transitioning to an operation for causing the cooling of the inside of the vehicle compartment by the air conditioning refrigerant circuit and the cooling of the heat generating apparatus by the branch refrigerant circuit to be performed in parallel, performs opening/closing control of the branch control valve in accordance with the cooling capability status of the air conditioning refrigerant circuit.
