Air conditioning system for vehicle

An air conditioning system for a vehicle that air conditions a vehicle cabin before a user gets into a vehicle, the air conditioning system comprising:

• an air conditioner configured to air condition the vehicle cabin;
• an outside air temperature sensor configured to detect outside air temperature of outside air;
• an inside air temperature sensor configured to detect inside air temperature of inside air of the vehicle cabin;
• a solar radiation sensor configured to detect solar radiation;
• an inside/outside switching door configured to switch air to be introduced between the inside air and the outside air;
• and
• a processor configured to actuate the air conditioner to air condition the vehicle cabin by increasing an air conditioning output for an output increase period after the user gets into the vehicle, wherein
• the air conditioning output includes a target blowout port temperature of the air conditioner and a target air volume flow of the air conditioner, and
• the processor is configured to calculate the target blowout port temperature, the target air volume flow, and a target opening amount of the inside/outside switching door based on the outside air temperature, the inside air temperature of the inside air, and the solar radiation, wherein
• the processor is configured to
• acquire the outside air temperature from the outside air temperature sensor, and
• in response to the acquired outside air temperature being equal to or higher than a first predetermined temperature,
• determine, based on the outside air temperature, an amount of the air conditioning output to be increased and the output increase period,
• correct, based on an amount of the solar radiation detected by the solar radiation sensor, the output increase period, and
• air condition the vehicle cabin by actuating the air conditioner with the determined amount of the air conditioning output to be increased and the corrected output increase period.
