To provide a vehicular air conditioner which reduces heat loss due to outside air introduction and inside air exhaust and can suppress power consumption during air-conditioning operation while improving blowing efficiency of the air in an air-conditioning case.SOLUTION: In a vehicular air conditioner 1, a first passage P1 guiding outside air from an outside air inlet 22 into an evaporator 32 and a second passage P2 guiding inside air from an inside air inlet 23 into the evaporator 32 are formed in an air-conditioning case 21. A blower fan 31 is provided in the first and second passages P1, P2. A total heat exchanger 34 is disposed between the blower fan 31 and the evaporator 32. In the total heat exchanger 34, the outside air flowing in the first passage P1 is guided, at least a part of the inside air flowing in the second passage P2 is introduced, and heat exchange occurs between the outside air and the inside air. The outside air which has undergone heat exchange is introduced into the evaporator 32 together with the rest of the inside air flowing in the second passage P2, and the inside air which has undergone heat exchange is discharged outside a cabin.SELECTED DRAWING: Figure 1
【課題】空調ケース内の空気の送風効率を向上させつつ、外気導入および内気排出による熱損失を低減して、空調動作時の消費電力を抑制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1は、空調ケース21内に、外気入口22から蒸発器32に外気を導く第1通路P1と、内気入口23から蒸発器32に内気を導く第2通路P2とが形成されている。第1および第2通路P1,P2内にはブロアファン31が設けられ、ブロアファン31と蒸発器32の間には全熱交換器34が配置されている。全熱交換器34には、第1通路P1内を流れる外気が導入されるとともに、第2通路P2内を流れる内気の少なくとも一部が導入され、外気および内気の間で熱交換が行われる。熱交換された外気は、第2通路P2内を流れる残りの内気とともに蒸発器32に導入され、熱交換された内気は車室外へ排出される。【選択図】図1
