Abstract
An air conditioner and a method for controlling an air conditioner which can operate in at least two operation modes, such as a cooling mode and heating mode. The capacity of the air conditioner is determined based on a difference between a set temperature and the temperature detected by a room temperature sensor every time a set time has elapsed, and the amount of variation of the detected temperature over the set time. The capacity can be controlled using PID control, fuzzy control, genetic algorithm control, or the like. The set time is varied based on the operating mode. Also, the set time can be varied in accordance with the volume of air blown into the room from the air conditioner, the direction of the blown air, the performance rating of the air conditioner and/or the size of the room to be conditioned.
