  • Compressor and air conditioner
    Patent number: 7739880
    Abstract: There is provided a compressor and an air conditioner capable of preventing a piston from being locked to a cylinder by iced matters. A compressor operation control section 18 of a control unit 20 stops the piston 2 in a high-temperature region HR of comparatively high temperatures where frost or ice of an inner circumferential surface of the cylinder 1 is less easily generated. As a result, generation of iced matters between the high-temperature region HR of the inner circumferential surface of the cylinder 1 and the piston 2 is prevented, so that a lock of the piston 2 due to iced matters can be prevented.
