Abstract

A driving unit and control method for a reciprocating compressor to control the frequency of input power so that the operating frequency of the compressor follows a resonance frequency that varies according to a change in load applied to the compressor. The reciprocating compressor includes an inverter that adjusts the frequency of the input power supply so that the frequency of the input power supply is set to a value corresponding to the resonance frequency through the inverter. The resonance frequency is set within a range between 60% and 90% of the normal power supply frequency. The compressor also includes a controller that controls the frequency of the input power supply so that the operating frequency of the compressor follows the resonance frequency that varies according to the operation of the compressor.

Description

technical field [0001] The present invention relates to a reciprocating compressor, and more particularly, the present invention relates to a drive unit and a control method for a reciprocating compressor for controlling the frequency of input power so that the operating frequency of the compressor is based on The resonant frequency varies with changes in the load applied to the compressor and is used to increase the efficiency of the reciprocating compressor in low load conditions. Background technique [0002] Generally, compressors are used in air conditioning systems, refrigerators, etc. to compress refrigerant. One type of compressor is a reciprocating compressor, which compresses refrigerant using a volume change in a compression chamber caused by reciprocating motion of a piston. Some reciprocating compressors use rotary motors as the drive unit, while others use traditional linear motors. [0003] A reciprocating compressor using a conventional linear motor is conf...
