If the Himalaya key 24 is input once, the Himalaya cool mode may be started, and if the Himalaya key 24 is inputted once more during the Himalaya cool mode, the Himalaya cool mode may be turned off. At the end of the Himalaya cool mode, the air conditioner may be operated in a normal cooling operation (non- Himalaya cool mode). That is, the off of the Himalayan cool mode may be a general cooling operation.

The Himalaya cool mode may be a mode in which the low-temperature air cooled by the indoor heat exchanger 8 is controlled in the set air volume mode and the set wind direction mode to efficiently cool the main residential area of the room at a high speed.

The Himalayan cool mode may be a special cooling operation (non-general cooling operation) that is controlled by the set air volume mode and has a set wind direction mode while using the set temperature as the target temperature.
