AIR CONDITIONER

摘要

In an air conditioner driven by a torque control inverter for restricting the speed variation of a rotor of a compressor motor, when an operation stop instruction is output, a compressor speed is first changed to a speed where an amount of torque control is equal to or more than a predetermined value, and then the compressor is stopped at a rotor position appropriate to control vibration occurring at the time of the stop. Further, a rotor stop position and a ratio of change in compressor speeds during the stop control above are determined in accordance with a compressor load.
