To provide a vehicular air conditioning unit capable of suppressing a change of an air quantity ratio between an outside air passage and an inside air passage caused by penetration of a pipe of a heat exchanger through an air-conditioning case.SOLUTION: A vehicular air conditioning unit 1 includes: an air-conditioning case 12; a cooling heat exchanger 16 for cooling air flowing in the air-conditioning case 12; high-pressure refrigerant piping 54 for supplying a refrigerant to a cooling heat exchanger 16; and low-pressure refrigerant piping 55 for discharging the refrigerant from the cooling heat exchanger 16. A partitioning wall section 13 for defining an upper layer passage 121 for causing outside air to flow in an inside/outside air two-layer mode and a lower layer passage 122 for causing inside air to flow in the inside/outside air two-layer mode is set in the air-conditioning case 12. A through hole 130 through which the high-pressure refrigerant piping 54 and the low-pressure refrigerant piping 55 penetrate is formed on the partitioning wall section 13.SELECTED DRAWING: Figure 2

    【課題】空調ケースに熱交換器の管を貫通させることに起因する外気通路および内気通路の風量割合の変化を抑制可能な車両用空調ユニットを提供する。【解決手段】車両用空調ユニット1は、空調ケース12と、空調ケース12の内部を流れる空気を冷却する冷却用熱交換器16と、冷却用熱交換器16に冷媒を供給する高圧冷媒配管54と、冷却用熱交換器16から冷媒を排出する低圧冷媒配管55と、を備える。空調ケース12の内部には、内外気二層モード時に外気を流すための上層通路121と、内外気二層モード時に内気を流すための下層通路122とを区画形成するための隔壁部13が設定されている。そして、隔壁部13には、高圧冷媒配管54および低圧冷媒配管55を貫通させるための貫通穴130が形成されている。【選択図】図2
