Abstract

The object of the present invention is to increase the comfortableness of personnel in an air-conditioned room by properly controlling both temperature and relative humidity in the room during the cooling operation of the air conditioner, wherein a target value set part (81) and a capacity control part (82) are provided in an air-conditioning device (air conditioner) (10). The target value set part (81) sets a target evaporating temperature value as a target control value during the cooling operation. The target value set part (81) determines the possible upper limit value of the target evaporating temperature value according to a value detected by a relative humidity sensor (78). The capacity control part (82) controls, during the cooling operation, the capacity of a compressor (30) so that a value detected by an indoor heat exchanger temperature sensor (76) becomes the target evaporating temperature value.
