The present invention relates to an air conditioning device for a vehicle. The purpose of the present invention is to improve the structure and air flow structure of a heat exchanger for heating and thereby reduce the electrical consumption of the heat exchanger for heating without reducing the comfort of the vehicle interior, and to differentiate the temperature of air discharged to the upper and lower sides of the vehicle interior. In order to achieve the above purpose, the present invention provides an air conditioning device for a vehicle, the air conditioning device comprising: a heat exchanger for cooling and a heat exchanger for heating which are sequentially installed on an internal flow path of an air conditioning case and cool and heat the discharged air of a blower; and a plurality of air discharge ports for discharging, to the vehicle interior, cold and hot air that has passed through the heat exchanger for cooling and the heat exchanger for heating. The air conditioning device is provided with: a first bypass flow path through which the blower-side discharged air that has yet to pass through the heat exchanger for cooling is bypassed to the upstream side of the heat exchanger for heating; and a first opening/closing door for opening and closing the first bypass flow path. La présente invention concerne un dispositif de climatisation destiné à un véhicule. Le but de la présente invention est d'améliorer la structure et la structure de circulation d'air d'un échangeur de chaleur assurant le chauffage et, ainsi, de réduire la consommation électrique de l'échangeur de chaleur assurant le chauffage sans réduire le confort de l'habitacle du véhicule, et de différencier la température de l'air libéré vers les parties supérieure et inférieure de l'habitacle du véhicule. Afin d'atteindre l'objectif ci-dessus, la présente invention concerne un dispositif de climatisation pour un véhicule, le dispositif de climatisation comprenant : un échangeur de chaleur assurant le refroidissement et un échangeur de chaleur assurant le chauffage qui sont installés de manière séquentielle sur un trajet de circulation interne d'un boîtier de climatisation et qui refroidissent et réchauffent l'air libéré par un ventilateur ; et une pluralité d'orifices de libération d'air destinés à libérer, en direction de l'habitacle du véhicule, de l'air froid et chaud qui a traversé l'échangeur de chaleur assurant le refroidissement et l'échangeur de chaleur assurant le chauffage. Le dispositif de climatisation comprend : un premier trajet de circulation de dérivation à travers lequel l'air libéré côté ventilateur qui doit encore passer à travers l'échangeur de chaleur assurant le refroidissement est dévié vers le côté amont de l'échangeur de chaleur assurant le chauffage ; et un premier volet d'ouverture/fermeture destiné à ouvrir et fermer le premier trajet de circulation de dérivation. 본 발명은 차량용 공조장치에 관한 것으로서, 난방용 열교환기의 구조와, 공기의 흐름구조를 개선함으로써, 차실내의 쾌적성을 저하시키지 않고서도 난방용 열교환기의 전기 소모량을 줄일 수 있고, 차실내 상,하측별 토출공기온도를 차등화시킬 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 공조케이스의 내부유로상에 순차적으로 설치되어 블로어의 토출공기를 냉각, 가열하는 냉방용 열교환기와 난방용 열교환기 및, 냉방용 열교환기와 난방용 열교환기를 통과한 냉,온풍을 차실내에 토출하는 복수의 공기토출구들을 포함하는 차량용 공조장치에 있어서, 냉방용 열교환기를 통과하기전의 상기 블로어측 토출공기를 난방용 열교환기의 상류측으로 바이패스시키는 제 1바이패스 유로와, 제 1바이패스 유로를 개폐하는 제 1개폐도어를 구비한다.
