Control method of air conditioner system for vehicle

A control method of an air conditioner system for a vehicle, wherein the air conditioner system is integrated with a cooling system to cool an engine and an intercooler, and the air conditioner system includes a water-cooled condenser embedded in an intercooler radiator and configured to condense a refrigerant by receiving cooling water cooling the intercooler in the cooling system, and an air-cooled condenser placed in front of the intercooler radiator and configured to condense the refrigerant supplied from the water-cooled condenser through heat-exchange with outdoor air, the method comprising:

• (A) circulating the refrigerant in the air conditioner system through actuation of a compressor by sensing actuation of an air conditioner while driving the vehicle in a state in which the start of the vehicle is on;
• (B) actuating a water pump circulating the cooling water and a cooling fan blowing wind to a cooling module;
• and
• (C) controlling the actuation of the compressor by judging whether the vehicle is in a failure mode in a state in which the air conditioner is actuated or normally driving the compressor and the cooling fan and ending the control,
• wherein the process (C) includes:
• judging whether the vehicle is in the failure mode while the vehicle travels in a state in which the air conditioner is actuated;
• stopping the actuation of the compressor or reducing a driving amount through a variable control, and returning to the process (B) if it is judged that the vehicle is in the failure mode;
• normally driving the compressor if it is judged that the vehicle is not in the failure mode;
• and
• normally actuating the cooling fan and ending the control when the compressor is normally actuated, and
• wherein the failure mode includes a case in which an error or a failure occurs in any one of a plurality of predetermined factors after checking every one of the predetermined factors, the predetermined factors including an air conditioner pressure, an engine cooling water temperature sensor, a vehicle velocity sensor, a normal range of an engine cooling water temperature, and/or a normal range of an intercooler cooling water temperature.
