| (54) | Apparatus and method for controlling sleep mode of airconditioner |
| (57) An air-conditioner and a method for controlling the same are disclosed. The apparatus
and method for controlling the sleep mode of the air-conditioner provides an optimum
air-conditioning effect suitable for individual sleep stages in consideration of temperature
characteristics of the sleep stages of a sleeping human being, such that it can provide
the sleeping human being with an optimum sleep mode. The apparatus includes a room
temperature sensor for detecting a room temperature; and a controller for controlling
the sleep mode when the sleep mode begins, such that it executes a sleep-entrance
stage for a rapid cooling mode during which the room temperature is quickly reduced
to a first temperature less than a setup temperature, executes a deep-sleep stage
for gradually increasing the room temperature to a second temperature higher than
the setup temperature, and executes a wake-up stage for increasing the room temperature
to a third temperature higher than the second temperature.
