1. A system for controlling an air conditioning system for a vehicle, comprising:
a plurality of sensors configured to sense: an opening/closing of at least one door, a fastening/unfastening of at least one seat safety belt, and a change in a vehicle height;
a first processor configured to: determine the number of all occupants in the vehicle by the opening/closing of the at least one door, the fastening/unfastening of the at least one seat safety belt, and the change in the vehicle height is sensed by at least one sensor of the plurality of sensors, and determine a preliminary internal circulation ratio of the air conditioning system according to the determined number of all occupants in the vehicle;
a second processor configured to adjust the preliminary internal circulation ratio into an adjusted internal circulation ratio according to at least one of: a sound intensity in the vehicle and/or a sound duration time in the vehicle; and
a controller configured to control the air conditioning system according to the adjusted internal circulation ratio,
wherein the second processor is further configured to determine: whether an occupant is on a call, to acquire a call duration time if it is determined that the occupant is on the call, not to adjust the preliminarily determined internal circulation ratio when the call duration time is equal to or lower than a first predetermined time, and if the call duration time is longer than the first predetermined time, to reduce the preliminarily determined internal circulation ratio by a first predetermined value at every first predetermined time interval until the internal circulation ratio becomes zero.
 
10. A method of controlling an air conditioning system for a vehicle, comprising:
sensing opening/closing of at least one door, fastening or unfastening of at least one seat safety belt, and a change in a vehicle height;
determining the number of all occupants in the vehicle by the sensed opening/closing of the at least one door, the fastening or unfastening of the at least one seat safety belt, and the change in the vehicle height;
preliminarily determining an internal circulation ratio of the air conditioning system according to the determined number of all occupants in the vehicle;
adjusting the preliminarily determined internal circulation ratio into an adjusted internal circulation ratio according to at least one of a sound intensity in the vehicle and/or a sound duration time in the vehicle; and
controlling the air conditioning system according to the adjusted internal circulation ratio, wherein adjusting the internal circulation ratio which is preliminarily determined includes:
determining whether the occupant is on a call;
acquiring a call duration time if it is determined that the occupant is on the call;
not adjusting the preliminarily determined internal circulation ratio if the call duration time is below a first predetermined time; and
reducing the preliminarily determined internal circulation ratio by a first predetermined value at a first predetermined time interval until the internal circulation ratio becomes zero if the call duration time is longer than the first predetermined time.
