1. An air conditioner comprising:
a compressor configured to compress a refrigerant;
a fan configured to discharge air cooled by the refrigerant; and
at least one processor configured to
receive a user input for setting an airflow volume of the air to be discharged and a desired temperature,
determine a temperature difference between an indoor temperature and the received desired temperature,
determine whether the temperature difference exceeds a critical temperature difference,
increase a frequency of the compressor to a first critical frequency and maintain the frequency of the compressor as the first critical frequency in response to determining that the temperature difference between the indoor temperature and the desired temperature exceeds the critical temperature difference while controlling the fan to discharge the air with the set airflow volume,
determine whether an unsatisfactory condition has occurred based on at least one cool air-conditioning sensation measurement item while maintaining the frequency of the compressor as the first critical frequency, and
increase the frequency of the compressor to a second critical frequency from the first critical frequency to further decrease a current temperature of the air to be discharged in response to determining that the unsatisfactory condition has occurred.

11. A method of controlling an air conditioner, the method comprising:
receiving a user input for setting an airflow volume and a desired temperature;
determining a temperature difference between an indoor temperature and the received desired temperature;
determining whether the temperature difference exceeds a critical temperature difference;
increasing a frequency of a compressor to a first critical frequency and maintaining the frequency of the compressor as the first critical frequency in response to the determining that the temperature difference between the indoor temperature and the desired temperature exceeds the critical temperature difference while discharging the air with the set airflow volume;
determining whether an unsatisfactory condition has occurred based on at least one cool air-conditioning sensation measurement item while maintaining the frequency of the compressor as the first critical frequency; and
increasing the frequency of the compressor to a second critical frequency from the first critical frequency to further decrease a current temperature of the air to be discharged in response to the determining that the unsatisfactory condition has occurred.
