Disclosed is a control method of an air conditioning system for a vehicle, which determines target sub-cool temperature of a refrigerant based on pressure and temperature of the refrigerant discharged from an outlet of a compressor when a compressor is operated, calculates an enthalpy change of the refrigerant during condensation and sub-cool processes of the refrigerant based on the determined target sub-cool temperature, calculates the enthalpy change of air passing an outer surface of a condenser based on the calculated enthalpy change amount of the refrigerant, and calculates required fan duty of a cooling fan based on the calculated enthalpy change amount of the air. The cooling fan can be configured to blow the air toward the condenser.

    개시된 차량용 공조시스템의 제어방법은, 압축기가 작동할 때, 압축기의 출구에서 배출되는 냉매의 압력 및 온도에 기초하여 냉매의 타겟 서브쿨온도를 결정하고, 결정된 타겟 서브쿨온도에 기초하여 냉매의 응축 및 서브쿨 과정에서의 냉매의 엔탈피 변화량을 계산하며, 계산된 냉매의 엔탈피 변화량에 기초하여 응축기의 외부표면을 통과하는 공기의 엔탈피 변화량을 계산하고, 계산된 공기의 엔탈피 변화량에 기초하여 냉각팬의 필요 팬듀티를 계산할 수 있다. 상기 냉각팬은 상기 응축기를 향해 공기를 송풍하도록 구성될 수 있다.
