Abstract
An air-conditioning apparatus having a refrigerant circuit including a condenser, a pressure reducing device, an evaporator, and a variable displacement compressor. The air-conditioning apparatus has a torque detecting device and an external information detecting device. The torque detecting device directly or indirectly detects the reaction torque acting on the compressor, and the external information detecting device detects various external information other than the torque. The air-conditioning apparatus further has a control device for determining a target torque in accordance with the external information provided by the external information detecting device. The control device executes a feedback control program for controlling the displacement of the compressor such that the torque detected by the torque detecting device approaches the target torque.
