  • Publication number: 20240254991
    Abstract: A compressor and a method for controlling the compressor detects the state of the suction refrigerant, thereby preventing the damage of the compressor and enabling stable operation. The compressor includes a compression unit equipped with a compression means for compressing a refrigerant, a motor unit coupled to the compression unit and compresses a suction refrigerant sucked through a suction port, an inverter unit with a detection unit for detecting a state of the suction refrigerant sucked through the suction port, and a control unit which controls the compression unit. The control unit controls by comparing a low flow condition which is set on the basis of a state in which the compression unit operates under an operating condition of a low refrigerant amount of the suction refrigerant and an actual flow condition of the suction refrigerant sucked into the motor unit when the compression unit is actually operated.
