Abstract: An air conditioner and a method of controlling the same are disclosed. The air conditioner includes a controller configured to determine a target evaporation pressure based on information sensed by an outdoor temperature sensor. The controller determines whether the determined target evaporation pressure is changed, based on a difference between a value sensed by an indoor temperature sensor and a set temperature of an indoor space and a value sensed by an indoor humidity sensor.
