METHOD FOR CONTROLLING OPERATION OF RECIPROCATING COMPRESSOR

摘要

PURPOSE: A method for controlling operation of reciprocating compressor is provided to keep the reciprocating compressor at optimum condition. CONSTITUTION: A method comprises a first step detecting peak value of current impressed to a motor to determine optimum condition and safe operating area of switching control signal when re-detection flag is set during operating at optimum condition; a second step determining fluctuation of current according to fluctuation of load; and a third step determining optimum condition or safe operating area of the motor according to duty rate of the switching control signal impressed to the motor.
