Driving controlling apparatus for reciprocating compressors, has power supply unit for controlling driving of compressor by applying added current to compressor, based on switching control signal generated by microcomputer

摘要

The apparatus (10) has a storage unit (70) for storing a current offset corresponding to a cooling capacity variable amount and an adding unit (80) for adding the current offset value to a current value applied to a compressor (50). A power supply unit controls the driving of the compressor by applying the added current, based on the control signal generated by a microcomputer (60). An Independent claim is also included for a method of controlling the driving of a reciprocating compressor.
