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

    【課題】補助暖房システムを利用した暖房運転時に、補助暖房システム側の凝縮器の温度が変化したときに、冷却水通路を流れる冷却水の温度の変化を迅速に回復させることができる車両用空調装置を提供する。【解決手段】車両用空調装置は、冷却水通路23Aと補助暖房システム14と制御装置21とを備えている。冷却水通路23Aは、内燃機関と熱交換した冷却水を、室内に吹き出される空気を加熱するヒータコアに流入させる。補助暖房システム14は、コンプレッサ13、凝縮器、暖房用膨張弁26、蒸発器を持つ冷媒回路30を有する。前記制御装置21は、凝縮器を流れる冷媒の圧力情報と、コンプレッサ13の運転状態情報とに基づいてヒータコアを流れる冷却水の温度を推定し、ここで推定した推定水温に基づいて補助暖房システム14を制御する。【選択図】図2
