Abstract
A control device for an air conditioner including a compressor driven by an inverter is disclosed. The control device comprises a floor temperature sensor as well as a room temperature sensor for detecting representative room temperature. A standard operation frequency of the compressor is determined on the basis of the difference between the target temperature and the representative room temperature detected by the room temperature sensor. Adjustment is made to the standard operation frequency according to the difference between the temperatures detected by the two temperature sensors, thereby obtaining an operation frequency of the compressor.
