PROBLEM TO BE SOLVED: To provide an operation control device of a reciprocating compressor and method thereof capable of reducing cooling capacity by preventing loss due to re-expansion. SOLUTION: The operation control device of the reciprocating compressor 50 controls a cooling capacity of the cooling device by varying an inner stroke of the compressor according to a stroke command value set by a user. The device is equipped with a storage unit 70 for storing a current offset value corresponding to a cooling capacity variable amount, an adding unit 80 for adding the current value applied to the compressor in accordance with that the cooling capacity is varied by the offset value and a user, a microcomputer for generating a switch control signal corresponding to the current value added from the adding unit 80 and a power supply unit 10 for controlling the operation of the compressor by applying the added current based on the switching on the control signal.
