초록 ▼

A system and apparatus for controlling the operation of a vibrating compressor using a predetermined frequency corresponding to the load thereof, comprising a first sensor for detecting a temperature of pressure corresponding to the saturated vapor pressure of a refrigerant sucked by a vibrating compressor, a second sensor for detecting a temperature or pressure corresponding to the saturated vapor pressure of the refrigerant compressed and discharged by the compressor, and a control section for generating a drive power of a predetermined frequency based on the temperatures and pressures detected by the first and second sensors, and characterized in that the compressor is driven by a drive power generated by the control section. In the present invention, the operation of the vibrating compressor can be controlled at the maximum efficiency by relating the frequency of an alternating current power fed to the vibrating compressor with the suction temperature or pressure and the discharge temperature of pressure of the refrigerant.

대표청구항 ▼

A system for controlling the operation of a vibrating compressor comprising: a first sensor for detecting the pressure of the refrigerant sucked by the compressor; a second sensor for detecting the pressure of the refrigerant compressed and discharged by the compressor; control means including means for converting signals detected by said first and second pressure sensors into predetermined electrical signals; computing means for generating an output having a predetermined frequency representing the frequency at which the compressor can operate at the resonant frequency based on the electrical signal from said pressure sensing means; and, a drive circuit for generating a drive signal corresponding to said output fed by said computing section.
