Zusammenfassung:Disclosed is a method to control an air conditioning system for a vehicle capable of minimizing operational power consumption of an air conditioning system and increasing a driving distance through an improvement of a cooling performance and pressure reduction. According to an embodiment of the present invention, the method to control an air conditioning system for a vehicle having a water cooling type condenser to condense a refrigerant using cooling water received from a cooling system to cool an intercooler or electric parts in a vehicle, and an air cooling type condenser arranged on a cooling module of the cooling system to condense the refrigerant received from the water cooling type condenser through heat exchange with outdoor air comprises: (A) a step of compressing the refrigerant by detecting the operation of an air conditioner while the vehicle drives in a state where the vehicle starts; (B) a step of circulating the cooling water cooled by heat-exchanging with the outdoor air in the cooling module to cool the intercooler or the electric parts; and (C) a step of controlling the operation speed of a water pump and a cooling fan by determining whether or not a vehicle speed, an air conditioner pressure, a cooling water temperature, and the temperature of the intercooler or the electric parts are within a predetermined set value, and finishing the control while maintaining the vehicle in an idle or driving state. 차량용 에어컨 시스템 제어방법이 개시된다. 본 발명의 실시예에 따른 차량용 에어컨 시스템 제어방법은 (A) 차량에서 인터쿨러 또는 전장부품을 냉각하는 냉각 시스템으로부터 냉각수를 공급받아 냉매를 응축시키는 수랭식 응축기와 냉각 시스템의 쿨링모듈에 구비되어 외기와 열교환을 통해 상기 수랭식 응축기로부터 공급되는 냉매를 응축시키는 공랭식 응축기를 포함하는 에어컨 시스템에서, 차량의 시동이 ON 된 상태에서 차량의 주행 중, 에어컨의 작동을 감지하여 냉매를 압축하는 과정; (B) 상기 인터쿨러 또는 전장부품을 냉각하도록 상기 쿨링모듈에서 외기와의 열교환으로 냉각된 냉각수를 순환시키는 과정; 및 (C) 차속, 에어컨 압력, 및 냉각수온과, 인터쿨러 또는 전장부품 온도가 기 설정된 설정치 내에 있는지 판단하여 워터펌프와 쿨링팬의 작동속도를 제어하고, 차량을 IDLE 상태 또는 주행 상태로 유지하면서, 제어를 종료하는 과정을 포함한다.
