A refrigerant suction guide structure of a reciprocating compressor is provided. The refrigerant suction guide structure includes a cylinder having an accommodating space inside, a piston having suction channels through which refrigerant is inhaled inside and inserted into the cylinder to be in a linear reciprocating motion, a suction valve included in the end of the piston to open and close the suction channels, and a valve fixing member for combining the suction valve with the piston. The suction channels of the piston include inclined surfaces for guiding refrigerant to the outside in which the suction valve is first opened. The suction channels are formed so as to be inclined to reduce flow resistance of inhaled refrigerant such that the amount of the inhaled refrigerant is increased. Therefore, it is possible to improve the efficiency of a compressor.

Provided is an apparatus for controlling an operation of a compressor which can always apply a constant voltage to the compressor without noise and a method therefor. The apparatus for controlling the operation of the compressor includes: a triac electrically connected to the compressor; and a controller for controlling a turn-on duration of the triac on the basis of a voltage value of an alternating current power applied to the compressor and a predetermined reference voltage value.

An apparatus for controlling an operation of a reciprocating compressor includes a inductance increasing device connected to a motor of the reciprocating compressor, so that a surge current generated when power is applied to the reciprocating compressor at an initial stage is reduced and thus an initial stroke of the reciprocating compressor is reduced. Accordingly, operational efficiency of the reciprocating compressor is improved.

A piston displacement device for a reciprocating compressor comprises a piston linearly reciprocated in a cylinder and having a stroke length varied by a reciprocating motor, a plurality of resonance springs for guiding a resonant motion of the piston, and a piston transfer unit for moving the piston forward or backward in a motion direction of the piston according to a capacitance variation of a compressor and thereby maintaining the same top dead center. The piston is moved according to a capacitance variation of the compressor thereby to minimize a dead volume thereof and to increase the efficiency of the compressor.

Disclosed are a reciprocating compressor and a refrigerator having the same. The reciprocating compressor comprises a casing, one reciprocating motor mounted at a frame unit provided in the casing for generating a linear-reciprocation driving force, a first compression unit for compressing a refrigerant directly sucked without passing through the inside of the casing by receiving the driving force of the reciprocating motor, and a second compression unit for mixing a refrigerant introduced into the casing and a refrigerant discharged from the first compression unit and then compressing the mixed refrigerant once more by receiving the driving force of the reciprocating motor. Accordingly, a refrigerant is consecutively compressed two times, components are simplified, and the compressor is easily controlled. Also, the refrigerator having the reciprocating compressor decreases a load of the reciprocating compressor thereby to enhance the efficiency of the refrigerator.
