Equipped with an inside/outside air ratio adjustment door and a mode control door that selects the air outlet to the passenger compartment, the interior temperature detected by the interior temperature detection sensor and the setting device that sets the interior temperature are set. In a vehicle air conditioning system that controls the blower air volume, the opening degree of the internal/external air ratio adjustment door, and the opening degree of the mode control door based on a signal related to the deviation between the internal combustion engine cooling water temperature and the a first determination means for determining the airflow rate of the blower, setting the airflow rate of the blower to a low airflow rate, setting the inside/outside air ratio adjustment door to an opening for introducing 100% outside air, selecting a heat outlet and a defrost outlet, and increasing the airflow rate from the defrost outlet; a first control means for controlling the air flow rate to a value approximately equal to the air volume blown from the heat outlet; a second control means for controlling the opening degree to a predetermined degree to mix the air return flow and controlling the air volume blown from the heat air outlet to be larger than the air volume blown from the defrost air outlet; and an air blower controlled by the second control means. a second determination means for determining that the air flow rate is less than a predetermined value when the air volume is controlled by a signal related to the deviation; and a second determination means for determining that the internal combustion engine cooling water temperature is less than a predetermined value by the first determination means When it is determined that the internal combustion engine cooling water temperature is equal to or higher than a predetermined value and the second determining means is generating a determination output, the first control means is activated.
