The present invention relates to an air conditioning system for a vehicle and a method for controlling the same and, more specifically, to an air conditioning system for a vehicle and a method for controlling the same in which an opening/closing valve and an expansion valve are installed on a branch line connecting a first air conditioning unit and a second air conditioning unit, the opening/closing valve is always open so as to always supply a refrigerant to the second air conditioning unit during a cooling mode, and the opening/closing valve is always closed so as to always block the refrigerant supply to the second air conditioning unit during a heating mode, such that the refrigerant flows into the branch line of the second air conditioning unit even during a single cooling mode, thereby solving the problem wherein the pressure of a compressor increases, oil is forcibly circulated through a notch of the expansion valve, thereby solving the problem wherein the oil circulation rate decreases, and the refrigerant supply to the second air conditioning unit is blocked during a dual heating mode, thereby solving the problem wherein the heating performance of an electric heating type heater decreases when the second air conditioning unit is operated.

    La présente invention concerne un système de climatisation destiné à un véhicule et un procédé de commande dudit système de climatisation, et plus précisément un système de climatisation destiné à un véhicule et un procédé de commande dudit système de climatisation, consistant : à installer une soupape d'ouverture/de fermeture et un détendeur sur une conduite de dérivation raccordant une première unité de climatisation à une seconde unité de climatisation ; à toujours ouvrir la soupape d'ouverture/de fermeture de façon à toujours fournir un réfrigérant à la seconde unité de climatisation pendant un mode de refroidissement ; et à toujours fermer la soupape d'ouverture/de fermeture de façon à toujours bloquer l'alimentation en réfrigérant de la seconde unité de climatisation pendant un mode de chauffage, de sorte que le réfrigérant s'écoule dans une conduite de dérivation de la seconde unité de climatisation même pendant un mode de refroidissement unique de façon à résoudre le problème selon lequel la pression d'un compresseur augmente, que de l'huile soit mise en circulation forcée à travers une encoche du détendeur de façon à résoudre le problème selon lequel la vitesse de circulation d'huile diminue, et que l'alimentation en réfrigérant de la seconde unité de climatisation soit bloquée pendant un mode de chauffage double de façon à résoudre le problème selon lequel l'efficacité de chauffage d'un appareil de chauffage de type à chauffage électrique diminue lorsque la seconde unité de climatisation est actionnée.

    본 발명은 차량용 공조 시스템 및 그 제어방법에 관한 것으로써, 더욱 상세하게는 제1공조유닛과 제2공조유닛을 연결하는 분기라인에 개폐밸브와 팽창밸브를 설치함과 아울러 냉방모드시 상기 제2공조유닛측으로 냉매를 항시 공급하도록 상기 개폐밸브를 항시 개방하고, 난방모드시 상기 제2공조유닛측으로의 냉매 공급을 항시 차단하도록 상기 개폐밸브를 항시 폐쇄함으로써, 싱글 냉방모드시에도 상기 제2공조유닛의 분기라인으로 냉매가 유입되어 압축기의 압력 상승 문제를 해결하고 팽창밸브의 노치를 통해 오일도 강제 순환되어 오일순환비율 감소 문제도 해결할 수 있으며, 듀얼 난방모드시에는 제2공조유닛측으로 냉매 공급을 차단함에 따라 제2공조유닛의 작동시 전기가열식히터의 난방 성능 감소 문제를 해결할 수 있는 차량용 공조 시스템 및 그 제어방법에 관한 것이다.
