To improve comfort of an occupant even just after switching an operation mode.SOLUTION: A vehicular air conditioner is provided with: a heat medium circuit through which a heat medium heated or cooled through heat exchange with a heat source circulates; an air-conditioning unit in which a heat exchanger that makes the heat medium circulating through the heat medium circuit exchange heat with air is arranged in an air flow passage and which blows out the air whose temperature has been adjusted by the heat exchanger to the inside of a vehicle interior; and a control part that controls the heat source, the heat medium circuit and the air-conditioning unit, and executes a plurality of operation modes while switching the modes. In switching the operation modes, the control part performs, when a target temperature set in the switched operation mode is higher than a threshold, pre-heating control of preheating the heat medium in the heat medium circuit or not, before switching the operation mode.SELECTED DRAWING: Figure 1
【課題】運転モードの切替直後においても乗員の快適性を向上させる。【解決手段】熱源と熱交換することで加熱又は冷却された熱媒体が循環する熱媒体回路と、前記熱媒体回路を循環する熱媒体と空気とを熱交換させる熱交換器を空気流通路に配置し、前記熱交換器により温調された空気を車室内に吹出す空調ユニットと、前記熱源、前記熱媒体回路、及び、前記空調ユニットを制御して複数の運転モードを切替えて実行する制御部と、を備え、前記制御部は、前記運転モードの切替に際して、切替後の前記運転モードに設定される目標温度が閾値より高い場合に、前記運転モードの切替前に前記熱媒体回路の熱媒体を予熱するか否かの予熱制御を行う、車両用空調装置を提供する。【選択図】図1
