An air conditioner capable of achieving both user comfort and power reduction is provided. The air conditioner includes a mean room temperature sensing mechanism 13 for sensing the mean room temperature of an indoor space, a normal target pressure memory 14 storing a normal target pressure set to a target value during normal control operation of a compressor controller and related with the outdoor temperature and air-conditioning load of the indoor space, a normal temperature difference computation unit 15 for calculating a temperature difference between a normal saturation temperature corresponding to the normal target pressure and the mean room temperature as a normal temperature difference, and a power reduction temperature difference computation unit 16 for calculating a power reduction temperature difference reduced from the normal temperature difference on the basis of a target power consumption decrement with respect to power consumption during normal control of the air conditioner, a compressor controller 18 is configured to control a compressor 5 by changing a power reduction target pressure, which is a saturation pressure corresponding to a power reduction saturation temperature calculated on the basis of the mean room temperature and the power reduction temperature difference, to the target value. |
