The present invention relates to an air conditioning system (1a, 1b) for a vehicle having a refrigerant circuit (2a, 2b) and a coolant circuit (30, 30a, 30b). The refrigerant circuit (2a, 2b) includes: a compressor (3); a refrigerant-cooler heat exchanger (4) which may be operated as a condenser/gas cooler to transfer heat between the coolant of the coolant circuit (30, 30a, 30b) and the refrigerant; a first expansion member (5); and a first refrigerant-air heat exchanger (6) for conditioning the introduced air for a guest room. The coolant circuit (30, 30a, 30b) includes: a feeding device (31); a first coolant-air heat exchanger (33) for heating the introduced air for a guest room; and a refrigerant-coolant heat exchanger (4). Further, the refrigerant circuit (2a, 2b) includes: a second refrigerant-air heat exchanger (9) for conditioning the introduced air for a guest room having a second expansion member (8) supported on the front side in a flow direction of the refrigerant. The coolant circuit (30, 30a, 30b) includes: a second refrigerant-air heat exchanger (34) for heating the introduced air for a guest room. Further, the present invention also is related to a method for operating the air conditioning system. Accordingly, a reheating mode can be operated.

    본 발명은 냉매 회로(2a, 2b)와 냉각제 회로(30, 30a, 30b)를 갖는 자동차 공조 시스템(1a, 1b)에 관한 것이다. 상기 냉매 회로(2a, 2b)는 압축기(3), 응축기/가스 냉각기로 작동할 수 있고 그리고 상기 냉각제 회로(30, 30a, 30b)의 냉각제와 냉매 간의 열전달을 위한 냉매-냉각기 열교환기(4), 제1 팽창 부재(5) 및 객실용 유입 공기를 컨디셔닝하기 위한 제1 냉매-공기 열교환기(6)를 구비한다. 상기 냉각제 회로(30, 30a, 30b)는 이송 장치(31), 객실용 유입 공기를 가열하기 위한 제1 냉각제-공기 열교환기(33) 및 냉매-냉각제 열교환기(4)를 구비하여 형성되어 있다. 또한, 상기 냉매 회로(2a, 2b)는 냉매의 유동 방향으로 앞쪽에 지지된 제2 팽창 부재(8)를 갖는 객실용 유입 공기를 컨디셔닝하기 위한 제2 냉매-공기 열교환기(9)를 구비한다. 상기 냉각제 회로(30, 30a, 30b)는 객실용 유입 공기를 가열하기 위한 제2 냉각제-공기 열교환기(34)를 구비하여 형성되어 있다. 또한, 본 발명은 상기 공조 시스템의 작동 방법과도 관련이 있다.
