Document Type and Number:
Japanese Patent JP6778871
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular air conditioner capable of promptly recovering a change of a temperature of cooling water flowing in a cooling water passage when a temperature of a condenser on an auxiliary heating system side is changed during a heating operation using the auxiliary heating system.SOLUTION: A vehicular air conditioner includes a cooling water passage 23A, an auxiliary heating system 14 and a control device 21. The cooling water passage 23A causes cooling water that has exchanged heat with an internal combustion engine to flow into a heater core for heating air to be blown out to an indoor side. The auxiliary heating system 14 includes a refrigerant circuit 30 having a compressor 13, a condenser, a heating expansion valve 26 and an evaporator. The control device 21 estimates a temperature of the cooling water flowing in the heater core on the basis of pressure information on a refrigerant flowing in the condenser and operation status information on the compressor 13, and controls the auxiliary heating system 14 on the basis of the estimated estimation water temperature.SELECTED DRAWING: Figure 2
