Abstract: An air conditioner and a method of controlling the same are provided. The air conditioner includes an outdoor unit provided with a compressor, an outdoor temperature sensor, an outdoor humidity recognition part, and a control part. The outdoor temperature sensor is installed on the outdoor unit to sense outdoor temperature. The outdoor humidity recognition part is installed on the outdoor unit to recognize outdoor humidity information. The control part controls an operation of the compressor, based information sensed from the outdoor temperature sensor and the outdoor humidity recognition part. When the outdoor temperature has a preset value, the control part determines target evaporation temperature such that the target evaporation temperature is decreased as outdoor humidity increases, and the control part drives the compressor at an operation frequency corresponding to the determined target evaporation temperature.
