To provide an air conditioner capable of utilizing a heater core, which is not used during cooling operation, to perform cooling.SOLUTION: In a vehicular air conditioner, a heater core 4 which heats air which has passed through an evaporator 3 with supplied hot water is provided at an air conditioning duct 12. An air mix door 14 which adjusts the quantity of air which passes through the heater core 4 is provided between the evaporator 3 and the heater core 4. The vehicular air conditioner is provided with: a cool storage tank 23 in which a coolant to be supplied to the heater core 4 is stored; and a cooling part which blocks the hot water to be supplied to the heater core 4 during cooling operation and supplies the coolant to the heater core 4 from the cool storage tank 23. When supply of the hot water to the heater core 4 is blocked and the coolant in the cool storage tank 23 is supplied to the heater core 4, the heater core 4 is cooled. Then, the air mix door 14 is opened to generate cool air which passes through the heater core 4. During the cooling operation, the air mix door 14 is opened to cause the cool air to flow through the heater core 4 and cool the coolant to enable cool storage of the cool storage tank 23.SELECTED DRAWING: Figure 1

    【課題】冷房運転時に使用しないヒータコアを利用して冷房を行える空調装置を提供する。【解決手段】空調ダクト12に、供給された温水によりエバポレータ3を通過した風を加熱するヒータコア4が設けられ、エバポレータ3とヒータコア4との間に、ヒータコア4を通過する風量を調節するエアミックスドア14が設けられる。ヒータコア4に供給する冷却水を溜める蓄冷タンク23と、冷房運転時にヒータコア4に供給される温水を遮断して、蓄冷タンク23から冷却水をヒータコア4に供給する冷房部とが設けられる。ヒータコア4への温水の供給が遮断され、蓄冷タンク23の冷却水がヒータコア4に供給されると、ヒータコア4が冷やされ、エアミックスドア14が開くと、ヒータコア4を通過する冷風が生じる。冷房運転時に、エアミックスドア14を開くことにより、ヒータコア4に冷風が流れ、冷却水が冷やされ、蓄冷タンク23を蓄冷できる。【選択図】図1
