Abstract

Disclosed is a method of controlling an air conditioner. A dehumidifying operation of the air conditioner is performed based on a relatively upper reference temperature when an indoor humidity satisfies a reference indoor humidity, and is performed based on a relative lower reference temperature when the indoor humidity does not satisfy the reference indoor humidity. The dehumidifying operation is performed in consideration of both temperature and humidity, and thus the temperature and the humidity of an air-conditioning space are maintained optimally.
