Abstract
A reciprocating compressor is provided that reciprocates a piston inside a cylinder as a linear motor is driven, to compress a refrigerant by sucking the refrigerant into a compression space between the cylinder and the piston, and then discharge the same. The piston is operated at a top dead center position and in a resonance state by symmetrically applying a voltage even if a load varies. An elastic coefficient of mechanical spring is set in consideration of a degree of shift of the piston influenced by gas springs varied by the load, and an initial value of the piston to maintain stroke of the piston is set so as to correspond to a required cooling capacity condition.
