PURPOSE:To achieve a comfortable air conditioning preventing vibrations and noises in the system of a compressor by arranging the correction value for the speed of a compressor to be larger when the room temperature deviates from the set temperature than when it approaches the temperature. CONSTITUTION:Outputs from an operation input unit 1 for entering the operation mode, a target temperature setting device 2 and a room temperature sensor 3 are inputted into a logical operation unit 4 comprising a temperature deviation detector 5, an initial speed setting device 6, an operation/stop signal generator 7, a temperature deviation detector 8, a temperature deviation upper limit detector 9 and a tunning speed holding device 10. The rotational speed of a steplessly speed changeable motor 12 for driving a compressor is controlled corresponding to a difference between the room temperature and the set temperature, namely, a temperature deviation through a motor operation controller 11. Here, the speed of a motor is changed at a larger rate when the room temperature deviates from the temperature than when it approaches the temperature. |
