摘要: An apparatus and a method for controlling a linear compressor, and a linear compressor operable with high power and low noise are provided. The apparatus may include a reference operating frequency determiner that determines a reference operating frequency at which a linear motor is operated, and an actual operating frequency determiner that determines an actual operating frequency as an arbitrary value included in a predetermined numerical value range in a vertical direction around the reference operating frequency. A correction signal may be determined by the actual operating frequency.

摘要: A linear compressor is provided. The linear compressor may include a shell including a refrigerant inlet, a cylinder provided within the shell, a piston that reciprocates within the cylinder, and a suction muffler provided movable together with the piston. The suction muffler may include a muffler main body that defines a refrigerant passage, a main body insertion portion press-fitted into the muffler main body, and a piston insertion portion press-fitted into the muffler main body to extend into the piston. The piston insertion portion may correspond to the main body insertion portion in configuration.
