To provide a vehicular air conditioner which can inhibit increase of a concentration of carbon dioxide in air inside a passenger compartment.SOLUTION: A vehicular air conditioner suctions inside air which is air inside a passenger compartment, and outside air which is air outside the passenger compartment, and blows cooled air into the passenger compartment. The vehicular air conditioner includes: a casing 10 which includes an inside air introduction port 11 for suctioning the inside air, an outside air introduction port 12 for suctioning the outside air, an inside air passage 151 for guiding the suctioned inside air to the inside of the passenger compartment, and an outside air passage 152 for guiding the suctioned outside air to the outside of the passenger compartment; a blower 35 which generates airflow in the inside air passage and the outside air passage; a refrigeration cycle which has an evaporation part 41 for cooling the inside air by absorbing heat from the inside air flowing in the inside air passage by use of evaporative latent heat of a refrigerant, and a heat radiation part 42 for performing heat exchange between the refrigerant absorbing heat from the inside air in the evaporation part and the outside air flowing in the outside air passage to radiate heat from the refrigerant; and an outside air introduction part 50 which guides a part of the outside air suctioned from the outside air introduction port to the inside air passage.SELECTED DRAWING: Figure 1

    【課題】車室内の空気における二酸化炭素の濃度の上昇を抑制可能な車両用空調装置を提供することを目的とする。【解決手段】車室内の空気である内気および車室外の空気である外気を吸い込んで車室内に冷却した空気を吹き出す車両用空調装置は、内気を吸い込む内気導入口11、外気を吸い込む外気導入口12、吸い込んだ内気を車室内に導く内気通路151、吸い込んだ外気を車室外に導く外気通路152を含むケーシング10と、内気通路および外気通路に気流を発生させる送風機35と、冷媒の蒸発潜熱を利用して内気通路を流れる内気から吸熱することで内気を冷却する蒸発部41および蒸発部において内気から吸熱した冷媒と外気通路を流れる外気とを熱交換させて冷媒を放熱する放熱部42を有する冷凍サイクルと、外気導入口から吸い込んだ外気の一部を内気通路に導く外気導入部50と、を備える。【選択図】図1
