Operation control method of reciprocating motion type compressor used in air-conditioner, involves applying direct current voltage and alternating voltage to compressor, when compressor load corresponds to specific load conditions

摘要

A direct current (DC) voltage and an alternating voltage are applied to a compressor (200) so as to increase the stroke volume of piston, when the load of the compressor, corresponds to predetermined load conditions. An alternating voltage is applied to the compressor, so as to control the stroke volume of the piston, when the compressor load does not correspond to predetermined load conditions. An independent claim is also included for driving control apparatus of compressor.
