摘要

ENERGY EFFICIENCY OPTIMIZATION SYSTEM AND METHOD FOR APPLICATION IN EQUIPMENT AND REFRIGERATION COMPRESSORS. The present invention relates to an energy efficiency optimization system for application in refrigeration equipment compressors. Such a system is provided with at least one main drive of the frequency inverter (10) and an electrically associated power supply (FAC) with each other. The main circuit of the frequency inverter (10) comprises at least one wave rectifier (4). In addition, the main circuit of the frequency inverter (10) comprises at least one bus capacitor (CB), electrically associated in parallel with the wave rectifier (4) and the compressor, electrically charged by a charging current. In addition, the frequency inverter main circuit (10) comprises at least one passive component (P), electrically associated with the wave rectifier (4), capable of reducing the load current of the bus capacitor (CB) and / or attenuating the harmonic content of an input current from the electrical power supply (FAC). Said system comprises at least one means for obtaining power at an input of the frequency inverter main circuit (10). Further, said system comprises at least one control unit (3) operatively associated with the means for obtaining power. Said frequency inverter main circuit (10) is provided with an electrically assignable active switch (K) parallel to the passive component (P), and the control unit (3) is configured to enable the active switch ( K) as a function of the input power of the frequency inverter main circuit (10). The present invention also relates to an energy efficiency optimization method for application in refrigeration equipment compressors.
