Abstract:
PROBLEM TO BE SOLVED: To provide a reciprocating compressor drive mechanism and its control method for controlling the frequency of an input power source so that the operating frequency of a compressor follows a resonance frequency which is varied with a load fluctuation applied to the compressor. SOLUTION: A reciprocating compressor has an inverter for adjusting the frequency of the input power source. The frequency of the input power source is set to be a value corresponding to the resonance frequency by the inverter. The resonance frequency is set to be a range of 60-90% of the frequency of a service power source. The reciprocating compressor according to this invention also has a control part for controlling the frequency of the input power source so that the operating frequency of the compressor follows the resonance frequency which is varied with the operation of the compressor.
